Are you still using traditional backup methods in your virtual environment? If so, you know these methods can create resource contention and capacity issues that eat up the cost-savings you were hoping to realize from your virtual infrastructure. Traditional backup is not efficient or effective in a virtual environment. You need an evolutionary shift in your backup strategy. You need EMC’s next generation backup technologies for your VMware environment.

    • Journey towards Virtualized Data Centre
    • VMware Environment:Business Problem and the Required Solution
      Business Problem
      Backup challenges limiting VMware ROI
      Not meeting VMware consolidation goals or backup and recovery SLAs
      Higher costs & increased Ops/Mgmt
      Technical Description
      Traditional backup processes cause backup bottlenecks
      Extended backup & restore times; limited server consolidation - increased hw spend
      Solution Required – Efficient VMware Backup, Maximizing ROI
      Minimal impact on virtual environment
      Achieve or exceed consolidation and migration goals – 2X consolidation ratio!!
      One step recovery; Flexible backup options for greater efficiency
      Results if achieved
      Increased server consolidation, lower HVAC/Floor space
      Lower operational costs, fewer host servers required
      Operational Mgmt Efficiency – greater TB’s per FTE, one-step recovery (file or image)

      Virtualization Backup and Recovery Challenges
      Virtualization changes the IT paradigm…
      Backup must evolve to deliver even greater consolidation and value
      NEW PARADIGM
      Virtual Environment: High overall server utilization and littlebandwidth for backup
      OLD PARADIGM
      Physical Environment: Low overall server utilization and plenty of bandwidth for backup

      The Way We HAVE to do it!
    • Using VCB
    • VCB concerns
      • Large investment in hardware
      • Proxy servers (1 per 3 ESX hosts)
      • 50% more disk required
      • San infrastructure for tape environment
      • Tape infrastructure
      • Implementation
      • Custom scripting required
      • No GUI interface
      • Encryption for tape infrastructure
      • Licensing
      • Additional backup server licences
      • Workflow
      • 2 Backups required to allow VMDK and file level restores
      • Restores are difficult and may need level 2 support
      • Vmotion, DRS, SRM are difficult to use with VCB
      • How do you replicate offsite?
    • Using VCB to Protect 20Tb of Cloud!
      • VCB and Tape Management System Acquisition
      • Hardware Purchase- IBM TS3500 with 10 TS1120 tape drives
      • $200,000
      • 7 Net Backup VCB SAN Media servers
      • 70,000
      • Software Purchase, Net Backup- 7 San Media server licenses
      • $35,000
      • San Infrastructure to support 7 Hosts and 10 tape drives
      • $34,000
      • Custom scripting and implementation for 7 VCB servers
      • 100,000
      • TS1120 tapes- 25 incrementals and 17 fulls plus offsite clones
      • 442 tapes to support 1 year retention
      • $22,100
      • Vaulting
      • $75,000 for three years
      • Storage
      • 50% More storage required for VCB
      • 10 TB’s at $8 per GB= $80,000
      Soft costs
      • 1 FTE to manage environment =120k x 3 years = 360K

    • Why use Guest level backup ?
      • Guest level backup are efficient; sourced based de-dupe allows for
      • Very efficient use of NIC, on average only .03% of data gets moved daily
      • Low disk/CPU utilization
      • Full backups take a fraction of the time versus traditional backups
      • Consolidate more guests per ESX server
      • Storage and protocol agnostic
      • Implementation
      • No Custom scripting required
      • Easy GUI interface
      • Built in encryption
      • Licensing
      • No client licenses
      • Workflow
      • Operations can easy manage a large Vmware environment
      • File level restores take seconds
      • No issues with Vmotion, DRS or SRM
      • Replication is very efficient. No need for backup tapes
    • The Alternative : Avamar/ Guest Level

      • Avamar agent resides inside each virtual machine
      • De-duplicates data within the virtual machine, as if they were physical servers
      • Moves minimal backup data
      • Reduces resource contention and accelerates backups
      • Provides file-level restore for Windows, Linux, and Solaris
      Cost to the Business: $554,000
      Saving for the Business: $572,100
    • Further Real World Proof ....
      • 59 ESX Servers Saved
      • $6.8M Saved over 3 Years
    • EMC Avamar #1 Source De-Dupe Technology
      Integrated backup solution with source-based deduplication
      • Next generation backup solution
      Integrated software & hardware solution with global source-based deduplication
      Deduplicates across sites and servers globally
      Effective full backup every time
      Single step recovery
      Backup process reduces data sent over the network and stored
      Variable-length subfile segments for optimal deduplication
      • Integrated high availability and reliability
      RAIN for high availability and fault tolerance
      Avamar server and data recoverability verified daily
      Replication between servers

      Scalable, turnkey solution small offices to datacenters
    • Source and Target Deduplication
      Network
      Network
      There are strong use cases for both technologies… but only source deduplication reduces network bandwidth requirements and decreases resource utilization during backups.
      DEDUPLICATION AT SOURCE
      DEDUPLICATION AT TARGET
      • Moves ~ 200 percent of primary data weekly
      • Up to 50 times reduction backup storage
      • Backups are typically restored from full and incremental images
      • Data viewed as file systems and/or virtual tape library target for traditional backup environments
      • Moves ~ 2 percent of primary data weekly
      • Up to 50 times reduction in backup storage
      • Up to 500 times reduction in network impact
      • Up to 10 times faster daily full backups
      • All backups are full; immediate, single-step recovery
      • Next-generation backup and recovery
    • Resource Usage Comparison
      CPU Usage
      Network Usage
      Disk Usage
      Significantly less CPU impact
      Give CPU cycles back to the applications
      Significantly less Network utilization
      Don’t be a backup scheduling master
      Significantly less Disk I/O
      Give back to the application
      At the end of the day your production applications should control the size of your VM infrastructure
      Backup is not ‘strategic’, it is a necessity – don’t let it control your VM infrastructure
