InternetVirtualization Needs a New Backup Strategy

Symantec says the advent of virtualization in enterprises means existing strategies for backup and recovery are inadequate, and require an overhaul.

MOUNTAIN VIEW, Calif. -- As enterprises move more heavily into virtualization, they will have to overhaul their data backup and disaster recovery strategies because these won't apply so well to the new virtualized world. That's the case Deepak Mohan, senior vice president of Symantec's (NASDAQ: SYMC) data protection group, made in a press briefing here at the company's offices where he discussed its strategies for disaster recovery, high availability and data protection. There are two major reasons why virtualization requires a new approach to data backup and disaster recovery, Mohan said. One is virtual sprawl, which is the unchecked proliferation of virtual machines (VMs) (define). "Virtual machines are easy to deploy and propagate like rabbits, and that causes complexity of management from the data perspective," Mohan explained. The other reason is the difficulty of protecting and recovering applications in virtual environments. Distributing applications across VMs or across both VMs and physical servers further strains the backup and recovery systems. Finally, VMs can be easily moved from one physical server to another, using applications like VMware's VMotion, which makes them more difficult to track and back up.
