  • The sheer volume of information and its continued growth is a root cause. Over the next four years, IDC estimates that the digital universe will expand by 400%, while IT budgets will expand just 20% and IT staffing 10%.Clearly, IT budgets can’t keep up with information growth and IT teams are expected to do more with the same staffing levels.At the same time, failure to properly secure and manage information is landing organizations in the news, because halting information flow means halting business. A Recent example of this in the US include the total loss of T-Mobile / Microsoft customer data after an upgrade went wrong. The information was eventually recovered days later, but during that time customers had no access to their email, contacts and calendar. Information outages and data breaches are headline news.There’s also a revolution going on in the data center around server virtualization, which provides terrific ROI in server consolidation. It also opens up the possibility of public and/or private cloud deployments in the future. Of course, the revolution around virtualization introduces a layer of abstraction and new tools, both of which increase complexity.
  • According to Gartner in its latest report for 2010, Symantec is the worlds largest provider of Backup and Recovery solutions. Symantec backups up more than half of the worlds business information. NetBackup has the largest global data protection footprint with 35,000 enterprise customers and nearly 2 million small to medium customers using Backup Exec. With such a large global footprint and protecting some of the largest enterprise customers on the planet, we understand the data protection needs of these organizations and work closely with them to provide the solutions to meet both current and future challenges.
  • The 5220 is the fourth NetBackup appliance released to the market in the last 12 months. Symantec offers both backup appliances and deduplication appliances which make it easier and more cost effective for customers to scale up performance. 1) The 5220 offers expandable storage (2U for the appliance with 4TB of dedupe disk and a 3U storage tray expansion for either 24 or 36TB of capacity). 2) If a customer needs additional capacity out of the gate, they can add 5000 series appliances in 16/32 TB blocks 3) The 5000 appliance series offer “global dedupe” across each node 4) Multiple connectivity options to receive & send data including FC
  • NetBackup 7 offers the industry’s first, highly scalable “end-to-end” global deduplication that is truly a fully integrated, seamless data protection software and appliance solution. No other vendor has the ability deploy such a flexible and cost effective solution built right into the backup software and support a wide range of compatible, highly scalable NetBackup Family Series of deduplication appliance solutions.A simple “click-of-the-mouse” enables the deduplication built into every NetBackup 7 client. This unparalleled flexibility allows you to optimize your enterprise data center today, and easily change your mind as it evolves, without a cost penalty. By upgrading or deploying NetBackup 7 agents across your virtual and physical environments, you will be able to dedupe at the client or source, at the Media Server, or target the NetBackup 5000 appliances with up to 192TB of Global dedupe pool today and nearly 400TB in the future. While enjoying the benefits and security of an Enterprise-class data protection solution you have grown to trust.The new 5200 series is the latest option to offer the fastest and most flexible method of deploying NetBackup and Dedupe in one shot. Also know as “NetBackup-in-a-Box”, NetBackup and Dedupe can be deployed as a scalable solution in the enterprise or easily in larger remote offices or as a complete backup or turnkey solution.
  • The NetBackup 7 release focuses not only on features, but also on the user experience associated with these features. Symantec recognizes the evolving nature of backup and recovery teams, towards less specialization, and the increased complexity of application backup and recovery. We focused improved usability efforts around deduplication, virtual machines, and replication.Dedupe Everywhere, Closer to the Source: Instead of taking the “brute force” approach of buying more and more storage, Symantec allows organizations to deduplicate information everywhere and closer to the source. Our new client/source-side deduplication allows customers to gain more than storage benefits from deduplication.While many organizations continue to deploy virtual servers with increasingly critical applications, they also continue to search for a better way to not only protect the information, but recovery information more quickly. Again, Symantec focused on how it could make virtual machine protection both simple and comprehensive. NetBackup can not only standardize VM data protection across multiple hypervisors, but offers unique features that improve backup performance, enable fast, single-file recovery, and simplify management and reporting efforts.For large organizations, backup is not local to one data center. They think about it data protection on a global scale. NetBackup 7 can help these organization deliver Better Disaster Recovery with Global Data Protection. Replication and deduplication are driving forces behind evolving DR approaches.Traditional disaster recovery approaches have begun to change as organizations seek to rationalize existing infrastructure already spread across sites and geographies. Again, with NetBackup 7, Symantec focused on how to make the management of global backup operations easier and how to improve their DR readiness with integrated replication features.
  • The traditional model of full and incremental backups impose high costs on most infrastructure components from the I/O system on the client to the storage on the server.<click>Using synthetic backup can reduce the I/O and network traffic during backup but increases the CPU and I/O overhead on the media server.
  • Using deduplicating storage on the backup server reduces the storage costs but does not affect the other overheads significantly.<click>Again using optimized synthetic backup can go some way to reducing the I/O and network traffic during backup but at the cost of increased CPU overhead on the backup server.
  • Client side deduplication reduces the network and storage overheads but increases the peak CPU loading on the client.
  • NetBackup Accelerator uses a combination of file tracking and backup synthesis to reduce I/O at all levels without impacting CPU loading. The accelerator agent ensures that, after the initial full backup, only changed data is ever sent from the client to the backup server. Combining this with client side deduplication can reduce the network traffic even further as only changed segments of changed files need to be transmitted.Unlike existing synthetic backup operations where the synthesis occurs independently from the backup, Accelerator full backups are automatically synthesized on the backup server at the time backup runs. In NetBackup 7.5 Accelerator supports file systems backup on Windows (NTFS) and Posix complaint UNIX/Linux file systems. It can take advantage of the Windows Change Journaling feature in NTFS to further accelerate the discovery process.
  • Replication Director reduces the administrative complexity around managing a combination of snapshots and backup by providing a unified NetBackup interface for configurationConfiguration of primary storage replication and snapshots is achieved using familiar NetBackup terminology and management paradigms and policies.SLPs control the whole process from initial snapshot creation through to long term backup storage including performing backups from snapshots.Snapshot content is catalog in NetBackup and search and restore can be performed across both snapshots and backups.During a typical sequence of operation: NetBackup quiesces entire stack and verifies consistent state of applicationA NetBackup policy initiates snapshot, replication of snapshot, and copy of replica to tape for archivingNetBackup is “aware” of all copies of the data and applies different retention dates to each copyReplication director reduces administrative overhead, reduces or eliminates the need for vendor-specific tools and knowledge and offers significant benefits in performance over conventional NDMP backup models.
  • The following steps illustrate Replication Director manages the creation of snapshots and their replication to a secondary site where the snapshot can be exported to tape or disk storage as a backup image. Note that in NetBackup 7.5 the two sites are part of the same NetBackup domain, in future releases Replication Director will have “auto image replication” capability to allow snapshots to be managed across domains.<click>First, if necessary, NetBackup quiesces the application. (Note, only file system snapshots are supported in NetBackup 7.5, application support will be introduced in future releases.)<click>Then a snapshot is created.<click><click>The snapshot is replicated to secondary storage<click><click>Then the snapshot is replicated again to the secondary site<click><click> This snapshot is mounted on a media server<click><click>And duplicated to create a backup image for long term storage on tape or disk.
  • So let’s drill into each area a bit more. Virtualization slows the backup process. Because backup is the process of copying data and moving it from one location to another, it requires server resources, specifically I/O and CPU power. This is in direct conflict with virtualized server environments which typically maximize all of a server’s resources. The result is that the backup of one virtual machine negatively impacts all the other virtual machines running on a physical server. Not only will those servers run more slowly, but the virtual machine backup itself may also be impacted. And because many virtual machines share network resources, the backup process often creates network bandwidth problems for other machines sharing that local area network.Plain and simple, virtualization increases backup storage consumption. How can virtual machine backups be different from standard physical machine backups? There are two important concepts here. First, many customers choose to backup both the individual files in a virtual machine as well as the entire machine (e.g., the VMware VMDK or Microsoft VHD). There’s a lot of duplicate data, such as OS data, in those virtual machine images that many customers backup every day. Second, even if you don’t do both of these types of backup, most customers will acknowledge virtual machine sprawl. Most or all of these servers in the so called “sprawl” need to be protected resulting in more backup storage consumption.Finally, if you are using virtual machine backups for disaster recovery, then you are probably storing full image backups from a number of days or weeks at both your data center and at your DR site. These images may give you faster recovery, but they consume a lot of storage. Do all of these VM backups need to be on disk? We would be talking about weeks of full server backup data often stored on disk.Virtualization improves the efficiency of the server team, but it can reduce the productivity of the backup team. How can this be you ask? Well, many companies often deploy different backup & recovery tools for virtual servers & applications. The result is that not all team members understand the backup process because of the increase of tools. Worse, you now need to monitor and report on backup activities across multiple applications. Did all your jobs complete with success? How much data are you protecting? Can everybody execute a recovery? You get the picture.What about recovery of specific files or directories?At EMC World 2009, a speaker stated that 80% of VM recoveries were for individual files. If you perform image-based virtual machine backups, you have no detailed file information within your backup catalog. This means that your backup administrator have to spend more time performing a recovery request. In fact, some IT teams simply refuse to perform individual file recoveries! Finally, let’s talk about the toll of administration and monitoring. How much time is your team spending making sure that they’re protecting all of the virtual machines deployed? If some virtual machines are intentionally not protected has that gap been documented with business owners? Separate backup tools for virtual and physical machines only makes this problem worse.
  • Last year Symantec conducted an extensive global survey of thousands of end-users. It is astonishing the nearly two-thirds of virtual machines are not backed up! The amount of risk businesses are taking on as a result of not backing up is amazing. There are some very real historical reasons for these results:1. Virtual machine sprawl – virtual machines spread like rabbits. Often times, IT just doesn’t know about the new machine (or knows about it but doesn’t know the RPT/RTO requirements/no SLA). This is one of the top reasons virtual machines are not backed up.2. Cost of backup agents – in the past, IT would have to buy individual backup agents for each new server. Potentially costing thousands of dollars...destroying much of the cost savings created with virtualization. 3. I/O & bandwidth impact – IT may have been concerned with dragging down the host machine and/or network by moving a lot of data for backup. The whole idea of virtualization is to increase server utilization/CPU utilization/network utilization and if you are successful, there is less “slack in the system” to handle backup loads.
  • Today many IT shops are backing up the same data two times in virtual environments: they backup the first time for full image recovery and then they backup a second time for more granular file, object recovery. The thinking is that when you want to recover a single email or a single calendar item from Exchange if you have only backed up the virtual machine then you will have to first restore the entire server, then recover the granular data you seek.The problem, as shown in the graphic, is you take twice as long, put twice the load on the network and you take up twice the storage capacity for the same data.Today, thanks to new capabilities from virtualization vendors and backup application vendors, there are solutions that allow you to do a single backup and still recover granular object items.
  • According to Enterprise Strategy Group most recent research (see appendix), 62% of companies still backup virtual machines this way. There are a lot of historical reasons for doing this, including a physical machine “mindset” in IT, uncertainty about the ability to recover granularly, and most importantly the limitations imposed by virtualization vendors. Example: VMware Consolidated Backup required a proxy server and had significant limitations for backup at the hypervisor level.The impact of this approach is significant: higher real costs (of agents) and unnecessary management complexity.Today, the virtualization vendors have improved APIs to support centralized backup and many vendors have the ability to backup at the hyper-visor level.
  • In a 2010 survey, customers were asked what approach they use today for physical and virtual machine backup: one single backup infrastructure or TWO separate infrastructures. More than half of IT shops use two vendors. The survey went on to ask what is your *preferred* approach, and IT shops correctly recognized the mistake of running two separate backup infrastructures and almost three quarters (74%) of them said a SINGLE vendor is the preferred. The growth of virtualization has been a lot like the growth of many disruptive technologies. In the early days of Linux, for example, there were specialized people and niche technologies that supported the exciting new technology. Today, Linux is simply part of how IT organizations work. Similarly, some organizations have developed a divergent approach to backup for their virtual servers. This is a mistake.What some people do:Using one tool for physical serversUsing a different tool for virtual serversWhy do some people do this:Limitations in backup support from VMware & Hyper-V Poor support from major vendorsVMware guy different than Backup guyLack of awareness of support from major vendorsWhy is this approach a problem?Inconsistent data management resultsConfusion and conflict between IT organizationsTurf wars, budget battles, etc.
  • How to Avoid?Explore your backup vendor solutions for virtualization. If your current backup solution doesn’t have strong support for both physical and virtual machines, find one that does.Get the virtualization & backup teams together, assign ownership & budget for backup of both physical and virtual machines.
  • NetBackup can help to simplify how organizations protect their virtual server environments by allowing them to centralize protection and recovery operations, to quickly find and recover individual files, and efficiently store and manage backup data. With NetBackup, virtual and physical servers are protected with similar types of policies, but different technologies, which makes administration easier. In addition to standard types of reports and alerts for backup operations, NetBackup offers specialized reports for VMware and Hyper-V environments that can lower the risk of missed backups or unprotected data.Market Pains: In the Symantec 2009 State of the Data Center survey reducing the impact of backup - and making it faster – and granular recovery of data from virtual machines were the top two concerns.Shorten Backup Window: NetBackup 7 can make all types of VM backups faster whether using hypervisor integration, such as our NEW support for the vStorage API, or client-based deduplication. Client-based deduplication can be one way effective way to shorten the backup times and it works across any hypervisor. For VMware and Hyper-V customers, we have hypevisor integration that provides more options for data center and DR recovery. As I mentioned, we now support the VMware vStorage API which allows for fast block-level incremental backup (BLIB). And we’ve gone further with our Windows support and can reduce the impact of backup for these environments.Of course customers using VM backups for disaster recovery as well, but backing up an entire VM each day takes time and storage. NetBackup 7 helps customer make these DR based-backups more quickly using incremental backups. An incremental VM backup can cut backup times by up 50-90%. More importantly, with NetBackup 7 – a customer doesn’t lose the ability to recover files.Speaker note only: Unique Proof Point - TODAY, NetBackup is the only vendor to enable incremental backups of a Hyper-V VMSymantec won recognition for its unique granular file recovery technology beginning with application like Microsoft Exchange. We delivered the same technology for both VMware and Hyper-V environments and allowed organization to perform one backup operation and to access two types of recovery – file or image based. (NetBackup won awards for VMware protection from SearchStorage in 2007 and 2008)Find & Recover Files Instantly: NetBackup 7 builds upon this technology leadership with improved usability, faster backups, and more unique file-level recovery features. NetBackup 7 addresses the first concern by allowing customers to immediately find and recover a file from ANY type of backup – whether it be a block-level incremental in VMware or an image-based backup of Hyper-V.NetBackup 7 also lets customer backup directly to tape and recover individual files or an entire VM directly from tape without the need for staging storage. The ability to recover without an additional operation and storage saves time and money.Speaker Note ONLY Unique Proof Point: TODAY, NetBackup is the only vendor that enables a customer to recover a file from a VMware block-level incremental backup (BLIB).Improving Storage Efficiency is important to any virtual machine backup strategy, especially given the increasing number of customers using VM backup to augment their DR strategy. The first and easiest place to start is with deduplication. NetBackup 7 deduplication can eliminate duplicate data across BOTH physical and virtual machine backups. And it doesn’t matter what type of backup you make. Storing less data not only reduces storage costs in the data center, but makes it easier to move data to a DR site using replication.NetBackup 7 offers even greater storage (and performance) benefits for VMware. We have a unique block-based optimization that allows for the most efficient backup possible. This feature allows NetBackup to skip deleted, unused, or worthless blocks. These can accumulate rapidly over the life of a VM and can easily represent between 10 and 30% of total data within a VM. For an organization with 10TB of VM backups and 20% unused blocks, this represents 24TB of data given over a retention time of 3 months or 12 weeks (10Tb *20% * 12 weeks = 24). That extra 24TB of reduced data movement and storage is significant given that the original VMs were only 10TB.We’ve talked about how NetBackup makes virtual server backup even better than physical server backups and how more organizations are using them for DR. That’s a great way to talk about our last focus area.Speaker Note only Unique Proof Point:TODAY, NetBackup is the only vendor able to offer this block optimizationSpeaker Background Here’s how block optimization works:When a file is moved or deleted, only the references to that file are removed. The data inside each block that used to be associated with the deleted file still exists. NetBackup knows this and can automatically skip these full but unused blocks (Windows). This can reduce the amount of backed up data by 30% or more when compared to standard backup technologies.
  • In addition to the unique ability to recover individual files from an VHD level backup, NetBackup 7 further improves how customers can protect Hyper-V environments. Shorten backups by up to 90%NetBackup offers the unique ability to perform a file-level incremental backup of a Hyper-V virtual machine (VHD). This allows customers to have a DR ready copy of data without needing the time and infrastructure of daily full backups of the entire virtual machine. Since most incremental backups are 10% of a daily full, this incremental backup approach can reduce the amount of data moved by up to 90%. Client-based deduplication also provides customers with another approach to reduce the impact of VM backups by eliminating full backups and only transmitting changed blocks on each backup. The overall backup is shorter and as much as 99% less data is transmitted.Protect critical applications in Hyper-V environments more easily with low, impact off-host backups. Hyper-V does not provide a specific backup API similar to VMware’s VMware Consolidated Backup or the vStorage API but it does provide the ability to integrate virtual machine split mirror and off-host backups with hardware vendors. This is essentially the same implementation as mirror based backups that are commonly performed with database applications but in this case the application is the Hyper-V system itself. NetBackup automatically controls the entire backup process including quiescing each virtual machine before the mirror is detached for backup.
  • The concern over individual file recovery from VM backups grew from 26% to 34% in the latest Symantec “2009 State of the Data Center Report”. NetBackup 7 addresses this need in a unique way for both VMware and Hyper-V.Previous to NetBackup 7, Symantec offered the unique ability to recover individual files or an entire VM from a single image-based backup. We offered this for both VMware and Hyper-V. With VMware this required the use of a the VCB framework and a proxy server. NetBackup 7 implemented the VMware vStorage API which offers block-level incremental backup (or BLIB). VMware BLIB offers a more efficient backup that eliminates the need for a proxy server, but it does not allow for individual file recovery.NetBackup 7 solves this problem and allows a customer to recover an individual file from any type of VMware or Hyper-V backup, including a VMware BLIB. Our unique file mapping technology allows us to keep track of which files changed regardless of the backup method. More importantly, an organization can recover an entire VM or an individual file. NetBackup 7 offers some additional features for VMware. In particular, it can recover the entire VM, in its exact state, in one step, regardless of the last backup type, using a new Guided Recovery Process. What do we mean by recovery of the VM in its exact state?In a traditional incremental based recovery process where each day, only new and changed files are backed up, the recovered virtual machine can have files or directories that were previously deleted. This occurs because the incremental recovery process only applies new files during the rebuilding process. So if a full occurs on Monday, and files are deleted on Tuesday, the incremental backup process on Tuesday does not capture those deleted files. As a result, the recovery of a full on Monday, and then the application of the Tuesday incremental will not reflected deleted files. NetBackup can eliminate this problem for VMware, allowing recovery of an exact state VM. Reporting on VM exposure
  • In NetBackup 7.5 there is a new policy type for VMware and it is no longer necessary to use the policy type of FlashBackup-Windows. However, for existing installations, the old policy type remains valid and there is no automated conversion of existing policies. Customers can manually convert their policies to the new type in their own time.The new policy type includes a tab...<click>...that has VMware specific settings on it
  • The same is true for Hyper-V policies. Again there is a new policy tab...<click>...that has Hyper-V specific settings on it
  • Virtual machines by design are easy to clone and deploy which explains why virtual machine sprawl is a growing management challenge within IT organizations today. Many IT managers would be hard pressed to give an accurate count as to how many virtual machines they’re running or whether or not they’re all being protected. And as the number of servers being virtualized grows, management of backup and recovery becomes more problematic. With Virtual Machine Intelligent Policy – backup admins can automatically discover new, cloned or moved Virtual Machiness and easily protect them without having to edit backup policies. Customers have been asking for this feature! It basically let’s you put virtual machine protection on “auto-pilot”Virtual machine Intelligent Policy automatically adjusts for any other changes that VMware technologies such as VMotion, Storage Vmotion, Distributed Resource Scheduling (DRS) etc. have made to every virtual machine. Virtual Machine Intelligent Policy is currently only available for VMware in the NetBackup 7.1 release….but support Microsoft Hyper-V is planned for future release.Another exciting feature within VM Intelligent policy is how you apply resource limits for load balancing and efficient throttling for better backup performance. Let’s look at that more closely (NEXT SLIDE)
  • The VM Intelligent Policy continues to grow by offering new vSphere 5 and vCenter 5 variables to use in queries. Three noteworthy additions have been made:vSphere 5 introduces a new storage concept called “Datastore Cluster”, which is fully supported. This is simply a collection of Datastores that acts as a single Datastore.We’ve also added several new Datastore attributes.Lastly, we’ve added the ability to include vCenter “custom attributes” into a query.The last capability is very powerful! Users can add any new variable, or custom attribute, to vCenter. NetBackup will show these attributes enclosed in square brackets, in this format: [user_custom_attribute]. For example, users could add a custom attribute called NBU_DISABLE_BACKUP with a true/false value. As shown in the screenshot, that value can be tested in the query. So in this example, VMware administrators can manipulate the NBU_DISABLE_BACKUP attribute on a VM to control whether (or not) it will be included in the next scheduled backup.That is just one example of the possibilities of leveraging vCenter custom attributes in the VM Intelligent Policy.
  • Customers have frequently asked for the ability to exclude VMDKs from VM backups. There are 2 common scenarios:They do not want to backup the OS, aka boot disk. In this case, they plan to use VM templates to recover the OS and file or application-recovery to recover the data.They do not want to backup the data disks. In this case, they data is protected using another policy-type, e.g. Oracle. They only need to recover the VM, and Oracle backups will be used for data recovery.Again, the VM Intelligent Policy come to the rescue by allowing users to optimize backups per their specific needs. By default, all VMDKs or virtual disks are included in a VM backup. But there is now an advanced setting toExclude the boot disk, orExclude the data disks.This feature is available on any VM which supports file-level recovery: Windows, Redhat, and SuSE.(Note: there are some implications when using this advanced setting with Application backups. Please consult the administration guide before using this feature with VM application backup.)
  • Another common request has been to report backup status within the vCenter console, also known as the vSphere client GUI. Now, you can have NetBackup report backup status directly into the vCenter console.There are 3 events that can be reported:Successful BackupFailed BackupCould not delete the VM snapshot after the backupThe last condition is important to the VM administrator, because the accumulation of VM snapshots can result in a VM performance penalty. With this visibility in the vCenter event log, VM admins now can react immediately and delete these snapshots directly. Otherwise, NetBackup will attempt to delete them later when the next backup is performed.To manage volume, users can also choose to only report errors, and do not report successful backups.
  • Here is a screenshot of a “backup failure” event as shown in the vCenter event log. It contains all of the necessary information for a VM administrator to forward to a NetBackup administrator, so they can quickly and easily investigate the failure.
  • Another notable enhancement is the support of vSphere 5 “Datastore Clusters”. Simply put, a datastore cluster is a new vSphere 5 storage container for grouping datastores. Generally speaking, a datastore cluster in simply one, large datastore comprised of smaller individual datastore. Consequently, NetBackup policies can now protect VMs that reside on a datastore cluster. And the VM recovery wizard now accepts a datastore cluster as a recovery destination.Here you can see a NetBackup browser for selecting a recovery destination of either a datastore cluster, or an individual datastore.When restoring into a cluster, vSphere 5 automatically determines which datastore will be the actual destination, based upon vSphere storage policy criteria.
  • Finally, there are some additional optimizations:The Linux EXT4 filesystem is now supported for file-level recoveryWe’ve added optimizations for excluding swap files and paging files, which are typically large and cannot be recovered.And let’s not forget Hyper-V!There is a new Hyper-V policy and all of the file-level recovery for Windows and Linux is also supported on Hyper-V too.
  • Previous versions of NetBackup offered sophisticated VMware virtual machine protection as well as advanced database protection with Symantec’s patent-pending Granular Recovery Technology (GRT). However, they were not integrated… database backups, with or without GRT, did not work with VMware VADP backups and required a separate backup pass, treating the virtual machine as if it were a physical machine. NetBackup 7.5 does away with this limitation, saving time, disk space, and money by integrating these two technologies for VMware virtual machines. Now it’s possible to perform a high-speed VMware VADP backup of a database server while retaining all the features of NetBackup’s advanced database agents, including item-level granular recovery. All of this is done in one fast backup pass – no more redundant copies of the same data. You can recover data at any level – full virtual machines, individual files, entire databases, or specific objects and items within a database. These recovery options work in exactly the same way as they always have in NetBackup, so there’s no need to retrain operators and database administrators. Setting up a VMware backup policy is easy – simple checkboxes allow you to select the types of databases that you’re protecting, optionally truncating database logs during the backup process. Virtual machines are automatically selected for backup using a VMware intelligent policy (VIP).
  • NetBackup’s new VMware application protection features work with Microsoft Exchange, SQL and SharePoint databases. The NetBackup client application must be installed in each virtual machine; the NetBackup client does not perform the backup itself, but it’s needed to assist with application consistency and granular recovery. An entire VMware-based database server can be restored in one operation for one-step disaster recovery, as well as individual files in the VM. Database-level recovery options are similar to those available for physical machines – entire databases can be recovered in a single operation, and single objects and items in Exchange and SharePoint databases can be restored quickly and easily. Note that the database recovery options require the backup image to reside on disk, rather than tape or virtual tape libraries. These features are currently not supported for Hyper-V virtual machines, but we expect to offer this capability in future NetBackup versions.
  • Too many copies. The primary. 5 snapshots. Daily incrementals. Weekly fulls. The archives.
  • Symantec advocates that customers deduplicate data everywhere, as close to the source as possible. Deduplication includes not just the reduction of duplicate backup data, but the reduction of old data off primary servers – archiving. Moving old data into an archive with Enterprise Vault, that also eliminates deduplicate data, benefits the backup and recovery process.With backup deduplication, the traditional approach has been to use appliances, which perform deduplication occurs at the end of the backup data path. This leaves significant savings on the table. By moving deduplication closer to the source, customers can reap more benefits from backup times, to network usage, to backup infrastructure.#1 We believe that most customers could use client side deduplication for as much as 50-70% of their data. The result will be faster backups, up to 99% less network usage, and of course, less storage consumption. NetBackup 7 deduplication is fully integrated and supports all clients, applications, and databases.Client Side Value: Faster Backups, up to 99% less network, fully integrated, and full application & database support#2 Of course, not all data is equal, and sometimes a particular client may not be suited to client-based deduplication. Or maybe a customer is not ready to upgrade their clients as part of a NetBackup 7 upgrade. For these instances, media server integration can be used. Regardless of whether client or media server is used, the data goes to the same disk target. A given media server can manage up to 32TB of deduplication data. A dedupe disk target can be configured with a simple wizard and commodity disk. Because we include replication and license based on a front-end / source data, it’s very easy and cost effective for a customer to begin replicating backup data to another location. We’ll talk about this more in the Better DR section of our presentation. The value of using commodity storage behind NetBackup for deduplication, especially when configured for replication, makes it easier to deploy deduplication everywhere. The savings can be up to 70% when compared to a replication approach with appliances.And going back to the usability theme, we mentioned earlier, we made it easy for organization to see their deduplication rates at a glance in the administration console. Backup Server: No Client Impact, Scales Efficiently, Easy Configuration, Up to 70% Less Than Appliances*#3 Of course, some customers may choose an appliance based approach for deduplication, despite the benefits of source-based deduplication, or may already have a dedupe appliance. NetBackup OpenStorage can turbo-charge these appliances giving customers more control and performance. The leading dedupe appliance vendors today, EMC/Data Domain, Quantum, and FalconStor all participate in OpenStorage and offer plug-ins for NetBackup today. Of course, the beauty about NetBackup 7 and OpenStorage is that a customer does not have to choose one or the other. A customer can have an appliance and still use NetBackup 7 client/source-based deduplication. True, the data will exist in separate “pools”, but the management of each copy of data at each location will be centralized by NetBackup. Organization can not only manage the policies centrally, but monitor and report on data on a global basis. Storage Appliance / OpenStorage: Simplify Management, Improve Infrastructure, Better PerformanceSymantec also kept in mind existing customers using PureDisk. NetBackup 7 is compatible with existing PureDisk storage pools which means that an existing customer can upgrade to NetBackup 7 and use the new client deduplication to backup to their existing PureDisk storage pool. Or they can use media-server deduplication to backup to a PureDisk storage pool.
  • Client deduplicationThis method reduced the amount of data sent over the network and stored. It does increase the CPU load on the client machine but for a relatively short period of time. This is ideal for remote offices, some virtual machines, and some LAN connected machines.
  • But with NetBackup 7 – Auto Image Replication – you can significantly extend the reach of your current Disaster recovery capabilities…while at the same time ….driving down the Total Cost of Ownership of global DRNetBackup 7 Auto Image Replication enables you to have multiple DR site that are located far enough away so as to be untouched by the disaster affecting the primary or secondary data site.
  • NetBackup’s Auto Image Replication allows you to automatically create copies of mission critical backups at a remote location that forms part of a separate NetBackup domain. This domain could be another data center belonging to the same organization, a dedicated disaster recovery site within the organization or even a third party disaster recovery facility. Once backup data is replicated, then you know your mission critical applications and data are ready to be restored at a moments notice. No tapes to search for, load and restore.Also importantly…you can easily set retention expiration policies at the target domains (sites) – so you can quickly make room for new backups to be replicated across and to minimize the storage impact to any site target. This also insures that none of your secondary site resources are unduly overburdened.So you can see why NetBackup Auto Image Replication disk-based duplication offers significant benefits over tape off-siting.Notes: Licensing AIR is part of the Storage Lifecycle Policies feature and requires the enterprise disk license for both the source and target domains. Customers using capacity based licensing do not have to pay a license fee for the target domain as capacity used by Auto Image Replication backups is only counted in the source domain and do not count towards the used capacity in the target domain. In the NetBackup 7.1 release the Auto Image Replication feature is only supported using the Media Server Deduplication Option to duplicate backups between domains. (Support for OpenStorage devices and PureDisk Deduplication Option are expected to follow in the first half of 2011.)
  • AIR “Import” is a) Immediate and b) Optimized (fast) operation:The OST API now provides an event mechanism for the OST plugin. When a new image arrives at the target site, the OST plugin will notify NB, and NB will immediately take action on the image.AIR “Import” is NOT the traditional (slow) import because the metadata is replicated directly to the target site, as a part of the image. (Traditional import has to read the whole image so as to construct the .f file.) The image metadata (the red block) is laid down on the source disk device as another fragment of the image. Therefore the replicating device will send the metadata to the remote site by virtue of replicating the image itself. The AIR “Import” process is a simple matter of moving the metadata into the catalog.Notice that the image metadata (the red block appended to the image) is removed when the image is duplicated to a traditional NB storage unit. There is no need to store the metadata with the image outside of the context of replication and import.
  • The only point here is that AIR supports a many-to-one, spoke-and-hub configuration across multiple NB domains.
  • The only point here is that AIR supports a one-to-many configurations as well. Yes, it supports many-to-many too.
  • For large organizations or enterprises with multiple locations and data centers, managing backup and recovery can be a challenge, especially if the goal is to improve efficiency and use of resources. NetBackup OpsCenter, a new component in NetBackup 7, offers out of the box reporting, alerts, and monitoring screens designed to streamline the operations of data protection.NetBackup OpsCenter replaces NetBackup Operations Manager (NOM) with usability and management improvements and also incorporates a previously stand-alone product, Backup Reporter. The business-level reporting , analytics, and 3rd party backup reporting features of Backup Reporter are now offered in OpsCenter Analytics. These features can be turned on with a simple license key from within OpsCenter, no additional software is required. OpsCenter Analytics provides multi product and platform support, business reporting, and complete customization (including customized and chargeback reportsandfull control on data retention).Because OpsCenter can centralize information from multiple sites, domains and versions of NetBackup, one team can view and assist other data centers or smaller sites through one console. Another new feature, not previously available in NetBackup Operations Manager, is the ability to report on Symantec backup and archiving (NBU, BE, and EV) products for no additional charge within OpsCenter. And if an organization has 3rd party backup products such CommVault, IBM TSM, or EMC Networker, they can standardize reporting from these product as well, through a quick and easy upgrade to OpsCenter analytics.Improved server efficiency is another part of the improvements offered with OpsCenter. Smaller customers, with only one master/media server, benefit from the ability to run OpsCenter on their existing NetBackup 7 servers, something that was not possible previously with NetBackup Operations Manager. For example, one of the more recent and popular reports is the ability to see quickly see both protected and unprotected virtual machines (Hyper-V and VMware only) with the click of mouse.
  • Audit Trails help you determine what changes are being made in the NetBackup environment. This can be very helpful especially when troubleshooting. For example, you can finally answer the question “What changed” when something that used to work, is no longer working. From a compliance or security stantdpoint it is also useful in detecting unauthorized access or changes to your backup environment. Some types of audit reporting OpsCenter can perform -- auditing of changes to storage units, storage servers and volume pools.Storage Lifecycle Policy Reporting – BecauseStorage Lifecycle Policies can be used to automatically create additional copies of data – it can create unanticipated loads on infrastrucuture. SLP Reporting gives greater visibility into your storage environment, it can help you better understand when there is not enough hardware to handle the load Storage Lifecycle Policy places on a backup infrastructure. SLP reporting provides drill-down reports on such things as Auto Image Replication jobs – if/when data was successfully replicated to the DR site; Backlog – showing which and how many backup jobs are unfinished. Workload Analyzer – reports can help a customer understand where there are available resources that can be used for backup and recovery. In many environments it seems that backups run 24/7 however they may not be actually using all of the resources available which reduces ROI. It can also show things such as when jobs are staying too long in the queue which means that too many backups might be starting at one time or that not enough resources are in the infrastructure to handle the jobs. On the flip side, it can also help you uncover additional or under-utilized resources for backup & recovery – and thereby allow you to postpone hardware purchases.Capacity based FETB License Reporting – If you’re currently a NetBackup customer using our Capacity (formerly called Front-End TB) licensing model, then this is a great tool for you. New OpsCenter 7.1 this feature helps you determines how much source data NetBackup is protecting in your environment – rather than the number of components deployed. NetBackup ustomers not using this model have to count the number of NetBackup Clients , Servers, and Options they would like to run NetBackup on or with and purchase the same number of licenses. If you’re considering moving to the Capacity model this OpsCenter tool (which is included as part of NetBackup) is very easy to use and can be a great help in calculating what you need to protect and how much Capacity Licensing is needed if you want to protect very large environments and leverage such advanced features as Enterprise Client, Application and Database Packs, Deduplication Option and RealTime
  • Symantec backup appliances provide many benefits over traditional build-your-own or point solutions. The benefits take the form of faster time to deployment, reducing risk, reducing planned and unplanned downtime, improving staff efficiencies, and enhancing service levels. Symantec offers a choice of form factors; NetBackup software or as an integrated NetBackup or Deduplication appliance. NetBackup Appliances are an all-in-one, integrated and performance optimized appliance based on the industries leading enterprise backup software, NetBackup. It provides a turnkey solution for customers that wish to rapidly modernize their data protection environment. In addition, Symantec provides a choice of appliances: NetBackup 5220 Backup Appliance: an enterprise backup appliance that installs in minutes, with expandable storage starting at 4 TB, and deduplication for physical and virtual systems.NetBackup 5020 Deduplication Appliance: offers scalable deduplication appliance solutions for the enterprise that provides operational simplicity, effective utilization of network bandwidth and storage, and high performance.
  • Symantec’s NetBackup Appliance family consists of two series; Backup Appliances which are the 5200 series and Deduplication Appliances which are the 5000 series. Let’s examine the NetBackup 5220 backup appliance. The 5220 starts as a 2U appliance with 4TB. It can scale with the addition of up to two (2) additional storage shelves. Each storage shelf is 3U and can expand the capacity in 24 or 36TB increments. Maximum usable capacity is 72TB. The 5220 can function as a media or a master server, and both can be easily configured with a simple mouse click through the NetBackup management console. The NetBackup 5020 is a deduplication appliance that supports 32TB of usable capacity. Up to six appliances or nodes may be connected to form a global deduplication pool of 192TB. Both the backup and deduplication appliances provide:source and target duplication, the only products in the market that provide this flexibility through a single, fully integrated appliance. Also, it provides multiple connectivity options for both Ethernet, 1 and/or 10Gig, as well as 8Gb fibre channel connectivity. Symantec has a unique front-end TB licensing model, so customers know exactly how much they are paying for in advance, regardless of their retention policy and/or the number of replicated copies they create. Software licensing is fully transferable, so this makes a great solution for media server replacements, just drop in the NetBackup appliance, transfer the licensing, and resume operations. Lastly, replication is included at no additional charge. With the NetBackup 5220 backup appliance and the NetBackup 5020 deduplication appliance, Symantec provides the choices that customer demand for their backup and recovery needs. *NetBackup 7.5 updates available for appliances late April / early May 2012
  • What is NetBackup appliance? Is it just NetBackup pre-installed on hardware? The answer is both yes and no! You may ask why?Yes, NetBackup appliance is simply backup in a box if you are looking for a solution for your data protection and disaster recovery readiness. That is the business problem you are solving with this turnkey appliance that installs in minutes and reduce your operational costs. No, NetBackup appliance is more than a backup in box if you are comparing it with rolling your own hardware for NetBackup or if you are comparing it with third party deduplication appliances. Here is why I say this…NetBackup appliance comes with redundant storage in RAID6 for storing your backupsSymantec worked with Intel to design the hardware for running NetBackup optimally for predictable and consistent performance. Eliminates the guesswork while designing the solution. Many vendors will talk about various processes running on their devices to perform integrity checks, some solutions even need blackout windows to do those operations. NetBackup appliances include Storage Foundation at no additional cost. The storage is managed by Veritas Volume Manager (VxVM) and presented to operating system through Veritas File System. Why is this important? SF is industry-leading storage management infrastructure that powers the most mission-critical applications in the enterprise space. It is built for high-performance and resiliency. NetBackup appliance provides 24/7 protection with data integrity on storage provided by the industry leading technology. The Linux based operating system, optimized for NetBackup, harden by Symantec eliminates the cost of deploying and maintaining general purpose operating system and associated IT applications. NetBackup appliances include built-on WAN Optimization driver. Replicate to appliances on remote sites or to the cloud up to 10 times faster on across high latency links. Your backups need to be protected. Symantec Critical System Protection provides non-signature based Host Intrusion Prevention protection. It protects  against zero-day attacks using granular OS hardening policies along with application, user and device controls, all pre-defined for you in NetBackup appliance so that you don’t need to worry about configuring it. Best of all, reduce your operational expenditure and eliminate complexity! One patch updates everything in this stack! The most holistic data protection solution with the least number of knobs to operate.
  • Symantec has listened to its customers and developed the NetBackup appliances to assist in lowering their operating expenditures. The need for fully integrated appliances is also supported by industry analysts, such as Robert Amatruda at IDC.
  • At Symantec we are focused on reducing the overall C.O.S.T of Enterprise Data Protection by 80% over the next 5 years. How we do this is to provide our customers with a single data protection platform that enables the reduction of all elements of how customers measure the expense and success of any data protection solution. These are: C – Capital Expense (CapEx) - ensuring our data protection provides the lowest storage cost for backup data. As well as optimizing the backup process to reduce the amount of data which is transported to perform the backup and recovery. O – Operational Expense (OpEx) - driving out operating cost by removing the need to manage multiple solutions or point products, to provide complete data protection while providing simple and turn key solutions.  S – Service Level Attainment (SLA) - providing optimized solutions for the different workloads that are being protected to ensure SLAs are never missed. T – Transformation - providing within the platform the ability for organizations to continue to protect their environment as new technologies and initiatives transform their environment such as virtualization and cloud. Let’s look at each of these four measures and how Symantec delivers NetBackup Appliances which helps our customers continue to reduce the C.O.S.T of data protection.
  • An important differentiator with Symantec is our software licensing. Software licensing is based on a front-end capacity license – allows customers to scale their capacity as needed. What is different are the 3Rs; replication, retention and refresh. Replication is included in our licensing. Compare this to our competitors who charge for every replication copy: Retention; competitors will charge for retention volume. Also, their software is tied to the hardware platform. This means their software license must be repurchased whenever the hardware is refreshed. Symantec reduces the CapEx of software licensing. Our hardware and software licenses are independent, giving customers the freedom to refresh their hardware without penalty.
  • The NetBackup 5220 appliance starts at a form factor of 2U with 4TB useable capacity. It can be easily expanded using either 24 or 36TB capacity storage expansion shelves with a maximum of 2 storage shelves. This provides a total maximum capacity of 72TB usable storage and 64TB of deduplicated storage.
  • Symantec appliances provides both scale-up and scale-out functionality. Scale-out occurs in three areas: Clients – the more clients running backups and dedupilcation, the greater processing power and that lowers the network bandwidth usage.Media servers – more media servers provide incremental process power and higher data ingest rates.Additional target deduplication appliances, depicted in the graphic, expands the global deduplication pool and provides higher processing power, while increasing the system capacity up to 192TB of global deduplication.
  • By offering an appliance, Symantec simplifies our customers lives through OpEx savings. This is evident in five key areas: Acquisition, Installation & Integration, Administration, Patching and Upgrades, and Support. Compare this to the complexity of building and supporting your own media server. There are numerous components which must be ordered, interoperability of the components must be verified, install and integration takes hours sometimes days, configuration is tested and performance tweaked. For administering the media server, the customer is faced with multiple components to manage, multiple patches, firmware updates that are separate and need to be tested. And lastly, support often turns into the finger pointing game with 3, 4 or even 5 vendors. With a build your own media server; there are five areas and four major components, a total of 20 cost factors. Compared to the fully intergrated NetBackup appliance, it is easy to see how OpEx savings are derived. As a fully integrated, tested, performance optimized solution, Symantec appliances provide significant benefits by reducing cost, complexity, and risk.
  • Symantec NetBackup provides many current and new features in NetBackup 7.5 which allow companies to improve their service levels and ensure all data is protected. Let’s look at a few features that address recovery point objectives (RPO) and recovery time objectives (RTO): NetBackup Auto Image Replication or AIR –initially released in NetBackup 7.1, AIR allows NetBackup users to improve Recovery SLAs and reduce both CapEx and OpEx costs. Automating the backup and recovery process and leveraging deduplication to efficiently duplicate data to a remote site; data replication is seamless, transparent and cost effective; failover is fast, and leverage existing secondary site resources to eliminate the need for costly, dedicated disaster recovery sites.NetBackup Accelerator – New in NetBackup 7.5, NetBackup Accelerator with its uniquely integrated change tracking and source deduplication not only provides better ways to manage and reduce CapEx costs, it can offer huge improvements in Backup and Recovery SLA performance. With NetBackup Accelerator full backups can happen in virtually the time it takes to do an incremental backup and restore the data at the speed and cost of a full backup. In some cases you will see backups happen up to 100x faster, and our remote offices tests have indicated up to 600X faster performance. Fast, cost effective, consolidated global data protection becomes a reality.Bare Metal Restore is integrated into NetBackup and is included at no extra charge. Bare Metal Restore provides all the files and services necessary to perform system recovery, including the ability to perform diskless network booting, temporary OS installation, and disk configuration. This allows a complete system recovery time of approximately 15 minutes on any platform, even disparate hardware platforms. NetBackup appliances have WAN optimization layer drivers built-in. This means reliable backups even in high latency environments. These industry leading features allow customers to implement the solutions and policies to attain their service level commitments.
  • Transformation is key to organizations success as they must protect their data today, while positioning and implementing solutions that will support dynamic growth and new technologies as they emerge. Four key areas are: Remote offices, providing streamlined solutions which eliminates the complexity of multiple point solutions and provides centralized management and data protection. With NetBackup appliances, remote offices can backup, dedupe, and then replicate the copies to the corporate office under the direction and control of headquarters staff. While backup takes many forms, recovery shouldn’t. Symantec backup and recovery solutions with V-Ray provide the single solution when recovery is needed, whether from tape, disk, snapshot, cloud – physical or virtual. As a single solution, NetBackup appliances backup and recover both physical and virtual servers.Tiered storage – NetBackup provides the backup and recovery solutions whether from tape, disk, snapshot; physical or virtual, and even cloud. Cloud storage is an emerging tool for data protection. It has the potential to significantly reduce OpEx and CapEx costs. In NetBackup 7.5, Symantec has expanded the number of cloud storage vendors to provide more choice and options.Every choice Symantec makes in designing and implementing NetBackup is made to eliminate complexity from our customer’s jobs as IT professionals. With features like bare-metal disaster recovery, AIR, WAN Optimization, Replication Director, and Accelerator, Symantec is delivering the best solutions for disaster recovery today, and in the future.
