How VM disk tagging works in conjunction with Commvault backups

There are three tags applied to all attached disks on a VM: NoDisks, OSDisk, and AllDisks. These tags, when used in conjunction with Commvault, indicate what level of protection a VM receives. The explanation for these tags and the level of protection follows.

NoDisks

A VM that has the NoDisks tag applied to all attached disks will not receive any form of backup protection from Commvault.

OSDisk

When the OSDisk tag is applied to hard disk 1, it will receive a weekly DR backup of the OS disk. Any additional data disks will be filtered from backup processing by having the NoDisks tag applied to them.

DR backups for the OS disk volume (scsi:0:0) run once weekly at each Data Center, on Mondays in Bloomington and on Tuesdays in Indianapolis, both at 6pm. These are full backups, kept for two weeks. To request an OS disk restore of your VM, email Storage and Virtualization.

AllDisks

A VM that has the AllDisks tag applied will receive daily backups of both the OS disk and all attached data disks. Backups for VMs that fall within this category will have a total of 14 versions, two full backups, and 12 incremental backups available for recovery. Recovery can be performed by the client at the file level, enabling granular recovery of a VM.
