In a recent survey, we asked the question, "Are you using the same backup tools for your virtual environment as you are for your nonvirtualized environment?" Seventy-five percent are using the same tools and of the 25% implementing new tools, we're seeing that people want management tools similar to storage system management tools integrated in the server virtualization management platform.
Take something like VMware Consolidated Backup (VCB). VCB is a kind of framework for the backup process that snapshots the network storage environment and allows the backup to take place without affecting the production environment. Using VCB you can actually take
virtual machine-level backups of those machines, but you can also provide file-level recovery. So, something that had been a two-step process can be performed in one step. You're also removing the backup traffic from the production LAN. And, you don't need the backup agent installed in the virtual machine.
