VMware Recovery: 77x Faster! NEW ESG Lab Review, with Veeam Backup & Replication

  1. 1. ESG Lab Review Veeam Backup & Replication Date: June 2011 Author: Vinny Choinski, Lab Engineer, and Lauren Whitehouse, Senior Analyst Abstract: This ESG Lab report documents hands-on testing of Veeam Backup & Replication. Topics explored include getting started with Veeam, Instant VM Recovery, Recovery Verification, and Universal Application-Item Recovery.The ChallengesOrganizations have enthusiastically adopted server virtualization and continue to expand their implementations beyondtest and development into production and mission-critical applications. But consolidating multiple workloads ontoindividual physical servers does add some risk; a single server failure now impacts more than a single application.Virtualizing tier-1 applications magnifies the importance of enabling quick recovery of virtual machines (VMs). In fact,when ESG recently asked IT professionals to identify where they expect to make the most significant data protectioninvestments, 30% indicated backup of their virtual environment, followed closely by improved application backup. 1Business managers have little tolerance for application downtime or lack of data availability, and IT managers needassurance that backed-up systems are recoverable.Virtualization helps to increase operational agility, facilitates higher availability, and reduces equipment and operationalcosts through consolidation. However, many existing backup solutions have not kept pace with these new environmentsand often negate the resource reduction benefits realized through virtualization. Traditional backup methods withagents in each VM can often increase the load on hosts and the time required to complete backups. A backup solutionthat can leverage the core attributes of virtualization—including cost, agility, and availability benefits—will acceleratethe virtualization of tier-1 mission-critical application workloads, which must be assured of high availability and fullprotection. This report examines an innovative VM backup and replication solution that speeds recovery time,streamlines the recovery process, and alleviates the fear of non-viable backups.The Solution: Veeam Backup & ReplicationVeeam Backup & Replication was built specifically for virtual environments to provide fast disk-based backup andrecovery of VMs. It offers a 2-in-1 solution of image-based backup and replication, enabling organizations to meetdifferent recovery time and recovery point objectives (RTOs and RPOs) for different VMs. Organizations can addressspecific budgetary and VM availability requirements by replicating on-site for high availability, replicating off-site fordisaster recovery, or backing up using cost-effective storage and techniques. Other features include instant file-levelrecovery and the ability to quickly provision a backup as an on-demand sandbox. It uses minimal resources and can scaleto any size environment through the use of multiple Veeam Backup Servers, which can be centrally managed via VeeamBackup Enterprise Manager.1 Source: ESG Research Report, 2010 Data Protection Trends, April 2010.

  2. 2. ESG Lab Report: Veeam Backup & Replication 2 Figure 1. Veeam Backup & ReplicationThe latest version of Veeam Backup & Replication includes a Windows service that enables the Veeam Backup Server toact as an NFS server and provide ESX(i) hosts with transparent access to backed-up VM images. This vPower technologyredirects changes that take place when a VM is running to a separate location, so backups remain unchanged. Inessence, vPower enables a VM to run directly from a compressed and deduplicated backup from any restore point(incremental or full).The VM does not need to be extracted, updated, and copied to production storage; instead, it is started directly fromthe backup in the backup repository, either in the production environment or in an isolated Virtual Lab that vPowercreates and manages. This enables Veeam Backup & Replication to offer several new capabilities (with multiple patentspending): • Instant VM Recovery – An entire VM can be restored from backup in minutes. Through Veeam vPower NFS, a vSphere host can connect to the native virtual machine files in the backup; by starting the VM from the backup, a failed VM can be quickly restarted on any host. Complete recovery is done by migrating the VM to production storage non-disruptively using Storage vMotion or by replicating or copying it to the production datastore. • SureBackup Recovery Verification – Automatic verification of the recoverability of every backup for every VM. Many organizations don’t test backups because it requires additional dedicated resources and time; instead, those responsible for disaster recovery simply hope that if needed, their backups will be recoverable. SureBackup automates verification using available resources in the production or test environment. Using Veeam vPower NFS and the Virtual Lab concept, the VM is run in an isolated environment directly from the disk-based backup; Veeam Backup & Replication starts the VM, boots the OS, and confirms that the VM is functioning properly. • Universal Application-Item Recovery (U-AIR) – Recovery of individual objects from any virtualized application. U-AIR is object-level recovery that needs no special agents, backups, or tools; it provides an elegant and inexpensive solution to problems such as accidental data deletion or corruption. With Veeam U-AIR, an application can be started on a recovery VM in a Virtual Lab from the desired restore point by leveraging Veeam vPower NFS. Once powered up, application objects can be copied to the production instance using a Veeam-provided proxy appliance. © 2011 Enterprise Strategy Group, Inc. All Rights Reserved.
  3. 3. ESG Lab Report: Veeam Backup & Replication 3Getting Started with Veeam Backup & ReplicationESG Lab found that getting started with Veeam Backup & Replication is an easy process. The application was available onthe Veeam Web site for download, and a 30-day evaluation key was provided. Once the application was downloaded, ittook about 15 minutes to install (including installing Microsoft SQL Server Express) and get to the login screen of theVeeam Backup Console (see Figure 2). Figure 2. Veeam Backup ConsoleThe Veeam Backup Console is used to configure and manage backup and replication attributes such as schedules,retention, targets, deduplication, and compression. Many restore options are also managed with this console.As shown in Figure 3, Veeam Backup Enterprise Manager is a Web-based management and reporting application thatcomes with Veeam Backup & Replication. It allows management of multiple instances of Veeam Backup & Replicationfrom a single console. Figure 3. Veeam Backup Enterprise ManagerVeeam Backup & Replication offers three distinct data transfer modes to provide flexible support for different VMwareenvironments. All modes leverage the vStorage APIs for Data Protection (VADP). Direct SAN access mode retrieves datadirectly from the SAN and can be used when the Veeam Backup Server has direct SAN access to VMware storage. © 2011 Enterprise Strategy Group, Inc. All Rights Reserved.
  4. 4. ESG Lab Report: Veeam Backup & Replication 4The Virtual Appliance mode requires that the Veeam Backup Server be installed in a VM running on an ESX(i) host withaccess to the datastores of the VM(s) to be backed up. With this mode, data is accessed via the ESX(i) I/O stack. Figure 4. Veeam Data Transfer OptionsLastly, Network mode can be used for VMware environments that use locally attached storage. With Network mode, VMdata is accessed over the LAN through the ESX(i) host using VADP and Network Block Device (NBD) protocol. In Networkmode, disk data can be transferred over an encrypted SSL connection.ESG Lab confirmed that Veeam Backup & Replication is a flexible solution that provides tightly integrated dataprotection for any type of VMware configuration. Its intuitive user interface is designed to walk you effortlessly throughthe configuration process; wizards help streamline the recovery process and the multiple deployment options enablegreater use of existing resources requiring less dedicated backup components than the traditional backup solutions. © 2011 Enterprise Strategy Group, Inc.

  5. 5. ESG Lab Report: Veeam Backup & Replication 5Instant VM RecoveryInstant VM Recovery enables recovery of a VM by presenting it to an ESX(i) host directly from a deduplicated andcompressed backup. Instant VM Recovery is made possible by exposing the virtual machine files in the backuprepository through an NFS mount, as shown in Figure 5. Veeam vPower NFS enables the Windows-based Veeam BackupServer to function as an NFS server. Instant VM Recovery reads data directly from the backup through the NFS mountpoint. The full recovery runs in the background while the VM is accessible to end users. The NFS mount point alsoprovides temporary write space to hold changes that would otherwise be made to the VMDK while the backgroundrecovery is in progress. Figure 5. Instant VM Recovery with Veeam vPower NFSFigure 6 shows the actual backups stored on the Veeam backup disk target. This is the data that is read during theInstant VM Recovery process. Figure 6.

  6. 6. ESG Lab Report: Veeam Backup & Replication 6The Instant VM Recovery process is managed through the Veeam Restore Wizard, which intuitively walks the userthrough the restore process. As shown in Figure 7, the wizard is used for Instant VM Recovery as well as many otherrestore options. Figure 7. Veeam Restore WizardESG Lab tested Instant VM Recovery of a 200 GB virtual machine compared to a standard full-image recovery using acompeting product, as shown in Figure 8. ESG Lab confirmed Veeam Instant VM Recovery was 77 times faster than thestandard full-image recovery tested. Figure 8. Veeam Instant VM Recovery vs. Standard Full-Image Recovery with Competing ToolThe testing compared Veeam Instant VM Recovery against a standard recovery from an image-based backup using acompeting backup application. In the standard recovery, the VM was restored from a deduplicated backup stored on adisk-based backup target. The detailed results for the 200 GB VM recoveries shown in Figure 8—as well as the results ofa 16 GB VM recovery—are documented in Table 1 and the accompanying bullet points. © 2011 Enterprise Strategy Group, Inc.

  7. 7. ESG Lab Report: Veeam Backup & Replication 7 Table 1. Detailed Results for Figure 8 Standard Veeam Improvement Full-Image Recovery Instant VM Recovery with VeeamRecovery Time for 695 113 6x faster16 GB VM (sec)Recovery Time for 8688 113 77x faster200 GB VM (sec)What the Numbers Mean • Veeam Instant VM Recovery was 77 times faster than a standard full-image recovery for a 200 GB VM. • Veeam Instant VM Recovery took less than two minutes no matter how large the VM. • The time savings become even greater as the VM to be recovered gets larger. • Recovery from a traditional file-based backup of a VM would show an even greater performance disparity.Why This MattersServer virtualization has accelerated the pace of business by enabling such feats as nearly instant infrastructureprovisioning with greater flexibility and availability. Realizing the benefits, organizations are working to virtualizemore production and mission-critical applications. At the same time, organizations have little tolerance for businessinterruption and downtime. In recent ESG research, 53% of respondents say they can tolerate less than one hour ofdowntime for tier-1 data without significant business impact.ESG Lab has validated that with Veeam Backup & Replication Instant VM Recovery, IT administrators can boot VMsdirectly from compressed, deduplicated backup files—enabling restart of a VM in less than two minutes. Thisfeature minimizes downtime and disruption to not only business users, but also IT. Users don’t have to wait toresume working until the entire VMDK file is recovered and presented back to production storage; in addition,recovery time is decreased and the recovery process more streamlined. © 2011 Enterprise Strategy Group, Inc.

  8. 8. ESG Lab Report: Veeam Backup & Replication 8SureBackup Recovery VerificationSureBackup Recovery Verification is the ability to verify a backup by using that backup to power up and test the VM thebackup was intended to protect. As with Instant VM Recovery, SureBackup Recovery Verification leverages VeeamvPower NFS to run a VM from a backup, but instead of running it in the production environment, it runs it in a VirtualLab, as shown in Figure 9. With SureBackup Recovery Verification, the VM is powered up and tested in a Virtual Labisolated from the production environment. Figure 9. Veeam SureBackup and U-AIRVeeam provides a proxy appliance with Veeam Backup & Replication to enable access to the Virtual Lab. This proxyappliance acts as a gateway between the production environment and the Virtual Lab. Figure 10 show the actual proxyappliance created as part of the ESG testing process. Figure 10.

  9. 9. ESG Lab Report: Veeam Backup & Replication 9ESG Lab validated SureBackup Recovery Verification by recovering an Oracle VM and a Microsoft Active Directory VM ina Virtual Lab environment. Virtual Lab options that enable granular resource configuration and allow applicationdependencies to be maintained during verification were explored.Figure 11 shows the memory allocation setup option. This option allows memory to be throttled back for SureBackupRecovery Verification VMs so as not to impact the production environment during verification testing (in the event thatproduction resources are used for Recovery Verification). The memory allocation option is set within the ApplicationGroup configuration. With Application Groups, VMs with application dependencies (e.g., Microsoft Exchange and ActiveDirectory) can be grouped and tested together to ensure complete application functionality. Figure 11. Virtual Lab Network SetupESG Lab confirmed that SureBackup Recovery Verification provides a flexible and comprehensive recovery test solutionthat can be run independently from scheduled backup operations.Why This MattersThe importance of having a viable backup cannot be overstated. Backups are needed to recover from disastersoccasionally, but they are frequently needed to recover from accidental deletions, failed updates, maintenanceproblems, and data corruption. However, the complexity as well as the time and infrastructure resources requiredto actually verify backups make it difficult for many IT organizations to test and, as a result, IT managers live in fearthat when a restore is needed the backup will be corrupted or unrecoverable. When asked about challenges theyexperience with current data protection processes and technologies, 42% of ESG respondents mentioned difficultyin validating backup/recovery success.ESG Lab tested the SureBackup Recovery Verification feature of Veeam Backup & Replication and found iteliminated the risk of unrecoverable backups by enabling IT to test every backup of any VM easily, quickly, andnon-disruptively. Using available test or production resources, Veeam Backup & Replication creates a VM in anisolated environment and runs it directly from the backup—starting the VM, booting the OS, and confirmingnormal functionality. The verification process is efficient, so not only is backup viability assured, it is accomplishedwithout distracting IT from other tasks. No additional backup infrastructure resources are needed. © 2011 Enterprise Strategy Group, Inc. All Rights Reserved.
  10. 10. ESG Lab Report: Veeam Backup & Replication 10Universal Application-Item RecoveryUniversal Application-Item Recovery (U-AIR) enables recovery of individual objects (e-mail messages, database records,directory objects, etc.) from applications running on VMs. U-AIR uses the same process detailed in the SureBackupRecovery Verification section of this document (see Figure 9). Once the VM is powered up, an application administratorcan recover objects from the VM running in the Virtual Lab and copy them to the production VM through the Veeam-provided proxy appliance, which has visibility into both the production and Virtual Lab environments.Like Instant VM Recovery, the U-AIR process is also wizard-driven. Figure 12 shows the Microsoft Active Directoryrecovery wizard; a Universal recovery wizard, Microsoft SQL Server recovery wizard, and Microsoft Exchange recoverywizard are also available. Figure 12. Veeam U-AIR Wizard for Microsoft Active Directory © 2011 Enterprise Strategy Group, Inc. All Rights Reserved.
  11. 11. ESG Lab Report: Veeam Backup & Replication 11ESG Lab leveraged the Universal recovery wizard to facilitate the recovery of an Oracle table space for an Oracle instancerunning on a VM. The JOB_HISTORY table was deleted from the production version of the Oracle database. A recoveryversion of the Oracle VM was then powered up in a Virtual Lab. Oracle SQL Developer was launched to view the point-in-time backup of the database that contained the JOB_HISTORY table space, as shown in Figure 13. Figure 13. Oracle Recovery View of JOB_HISTORY TableThe red box in Figure 13 highlights the JOB_HISTORY table space from the point-in-time view of the Oracle Recoveryinstance. Note that the JOB_HISTORY table space is missing from the Production Oracle instance (shown at the bottomof the directory tree in the left pane). © 2011 Enterprise Strategy Group, Inc. All Rights Reserved.
  12. 12. ESG Lab Report: Veeam Backup & Replication 12Oracle SQL Developer was then used to copy the missing JOB_HISTORY table space from the recovery instance of Oracleback to the production instance of Oracle. As shown in Figure 14, the CREATE TABLE command was successfully used todo a hot insert of the missing table space into the running Oracle production instance. Figure 14. Oracle Table Space RestoreWhy This MattersProtection of business applications is a high priority for organizations. When asked to cite their most significantdata protection priorities, more than a quarter of participants in recent ESG research mentioned improvingapplication backup. Common IT problems come from users accidentally deleting e-mails, records beinginadvertently overwritten, etc.; performing a full application recovery in order to restore these individual objectswastes productive time and resources. This type of task is the antithesis of what server virtualization isimplemented for: high availability, streamlined processes, and improved service levels.ESG Lab confirmed that the U-AIR feature of Veeam Backup & Replication allows recovery of individual applicationobjects for any virtualized application without additional backup agents or special backups. Veeam accomplishesthis by running the application in an isolated environment directly from the backup. As a result, it is less expensiveand more reliable than standard object-level recovery methods and works with the native utilities and permissionsof the virtualized application. © 2011 Enterprise Strategy Group, Inc.

  13. 13. ESG Lab Report: Veeam Backup & Replication 13The Bigger TruthServer virtualization has been widely implemented by organizations of all sizes as they recognize not only the economicbenefits of consolidating workloads, but also greater flexibility, ability to quickly provision new applications, andopportunity to increase data and application availability. In recent ESG research, 93% of respondents reported that theyare either currently using server virtualization or are in the evaluation and planning phases. In addition, these surveyrespondents plan to expand their virtualization implementations over the next 24 months, with 58% planning to havevirtualized more than 40% of their servers by that time. They also plan to increase the percentage of virtualizedproduction applications from 39% to 58%. 2This demonstrates the continued infiltration of virtualization into tier-1 data and explains why backup of VMs is such acritical topic. Like other IT processes, backup methods were built for the one-application-per-server paradigm. Backupsolutions presumed that only a single workload at a time would be interrupted by backing up a server; that is no longertrue with server virtualization and as a result, backing up multiple VMs can clog networks and interrupt operations.Trying to make physically-based backup work in the virtual domain has proven difficult and has left IT spendingsignificant effort without much confidence that backups have been done properly and will be recoverable. When youadd these challenges to a generally low tolerance for downtime, particularly of tier-1 data, it is clear that a fast, reliable,non-disruptive backup solution purpose-built for VMs is urgently needed.ESG Lab has verified that Veeam Backup & Replication offers an innovative “virtualization-powered” solution to VMbackup that matches virtualization’s key benefits: reducing costs and improving service levels. By creating a way for aVeeam Backup Server to act as an NFS server, the Veeam solution can run a VM directly from a backup on disk, enablinginstant recovery of VMs, the ability to automatically and non-disruptively verify backup recoverability, and object-levelrecovery from any virtualized application. ESG Lab found Veeam Backup & Replication easy and fast to install, with anoption for each backup job to be processed via the SAN directly, via the ESX(i) I/O stack, or via the network. ESG Labtested Instant VM Recovery of VMs in various sizes; no matter what size VM was tested, the Veeam method took justunder two minutes. In contrast, standard recovery time grew from approximately 11 minutes to nearly 2.5 hours as theVM size grew from 16 GB to 200 GB. ESG Lab also verified a backup, including starting the VM and booting the OS.Finally, the U-AIR feature was tested and functioned as advertised; a deleted a Microsoft Active Directory user accountwas recovered and a deleted table space from an Oracle database was quickly restored.The features we tested demonstrate clearly that Veeam Backup & Replication addresses the key challenges of ITmanagers and the needs of users. Instant VM Recovery returns users to productivity by enabling VMs to be restarted onany host in minutes, while relieving IT of emergency full restores. The SureBackup Recovery Verification feature relievesIT of worrying that backups are not viable by providing a fast and non-disruptive method of testing every VM backup,and the U-AIR feature provides object-level recovery quickly and inexpensively.
