Backup is a Key Virtualization ConsiderationOrganizations top server virtualization initiatives for 2010
Consolidate more physical servers onto virtualization platforms
Improve backup and recovery of virtual machines
Expand number of applications running on virtual machines
Make use of virtual machine replication for disaster recovery
Increase security of virtual server environment

The “Must Have” ListBackup for VMware solutions
• Must address issues, smooth phase transitions
– Resolve resource contention– Support both guest and image level backup– Provide both file and full virtual machine
recovery
• Must provide business value– Offer value for both physical and virtual
worlds – Reduce downtime, cost and risk
• Must integrate with VMware infrastructure
– VMware vStorage API; VMware vCenter Server
– VMware Site Recovery Manager (for DR automation)

Deduplication is the Key • Relieve resource contention
• Support rapid virtual machine cloning
• Contain backup storage growth
• Enable more effective disaster recovery

Move Less DataData deduplication is the enabler
1. Divides data into sub-file segments2. Determines if segments are unique or
duplicate3. Backs up only data that is unique4. Sends data compressed and encrypted

Avamar for VMwareOptimized for VMware backup
• Guest backup– Low impact agents, relief from resource
contention issues
• Image backup– Integrated with VMware vStorage API
• Easy file-level recovery from image backup
• Tight VMware vCenter integration
• Deployable as a virtual appliance—Avamar Virtual Edition
