Virtual Machine Basics Virtual Machines s ESX Server Physical Server s s Storage VM3.vmdk VM2.vmdk VM1.vmdk A virtual machine (VM) is the encapsulation of the guest, application & data Multiple VMs run in an isolated environment independently Each VM s image or hard drive is stored as a.vmdk file on local disk or networked storage Slide 5 Copyright 2008, The Enterprise Strategy Group, Inc.
Backup Challenges with VMware Increased amount of data that would normally be kept on a single physical server Backup processes can be resource intensive, potentially affecting operations on other VMs VM image files must be quiesced before backup VM image files increase the amount of data backed up and transferred over the network Slide 6 Copyright 2008, The Enterprise Strategy Group, Inc.
Backing Up Virtual Server Environments Which of the following technologies does your organization utilize to back up its virtual server environment? (Percent of respondents, N = 365, multiple responses accepted) Backup agent installed on host 46% Backup agent installed in guest 40% Server virtualization vendor's tools Customized scripts Backup of live snapshots Backup software integrated with virtualization vendor's tools Storage system's data protection features 29% 28% 25% 25% 23% Agent-less backup software 14% Don't know 4% Other 1% 0% 5% 10% 15% 20% 25% 30% 35% 40% 45% 50% Source: ESG Research: The Impact of Server Virtualization on Storage, December 2007.

Guest Level Backup Backup agent installed in VM Virtual Machines Advantages Enables file-based full, incremental, differential and application-specific backup for granular recovery s s s Trade-offs Resource intensive ESX Server Requires setup for each agent Doesn t provide bare metal recovery of VM Physical Server Storage VM3.vmdk VM2.vmdk VM1.vmdk Slide 8 Copyright 2008, The Enterprise Strategy Group, Inc.
Service Console-based Backup s Backup agent installed in Service Console Virtual Machines s s Advantages Virtual disk images easily backed up Bare metal recovery enabled Doesn t require networked storage ESX Server Trade-offs File-level restore not possible VM3.vmdk Single bottleneck & point of failure Physical Server Storage VM2.vmdk VM1.vmdk Virtual disk image breaks incremental backup strategy Slide 9 Copyright 2008, The Enterprise Strategy Group, Inc.
VCB-based Backup Backup agent installed on backup proxy Advantages Eliminates backup window for VM Full image or file-level recovery Virtual Machines s ESX Server Physical Server s s Backup Proxy Server & Storage Storage Snapshot Mount Eliminates agent in VM Allows for full, incremental, differential strategies Trade-offs File-level backup & incremental strategy for non-windows VM not supported No application granularity for recovery Requires integration scripts or VCB-enabled clients Requires physical proxy server or one running in VM Requires networked storage Slide 10 Copyright 2008, The Enterprise Strategy Group, Inc.
