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


Why Avamar?Deduplication backup system

• End-to-end, software/hardware solution

• Improves backup window, less network load

• Integrated high availability and reliability

• Flexible deployment options– Avamar Data Store– Avamar Virtual Edition

Full backups, every time—one-step recovery

Higher backup success rate and reliability

Increased ROI, lower TCO, less risk

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
