Commvault backups and VM disk tagging

The following explains how VM disk tagging and backups work in Commvault.

On this page:


VM disk tags and levels of protection

In Commvault, tagging indicates the level of backup protection applied to a virtual machine (VM). Three tags may be applied to all attached disks on a VM: NoDisks, OSDisk, and AllDisks.

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 when they have the NoDisks tag.

  • Provides disaster recovery protection for your OS disk volume (scsi:0:0)
  • All other attached disks will be skipped and unavailable for recovery
  • Full backups of the OS Disk run once weekly per Data Center, on Mondays in Bloomington and on Tuesdays in Indianapolis, both at 6pm
  • Backups are kept for two weeks
  • OS Disk recovery is not available for self-service and requires assistance from the Storage and Virtualization team

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 in this category have a total of 14 versions, two full backups, and 12 incremental backups available for recovery. The client can perform recovery at the file level, enabling granular recovery of a VM.

  • Provides full VM protection
  • Processes one full and six incremental backups each week
  • Lets clients self-service file level recoveries from any of the 14 days of available backups
  • Provides a full VM disaster recovery process that can be performed on either the entire VM, the OS disk volume (scsi:0:0), or any of the attached disks; this type of recovery is not available for self-service and requires assistance from the Storage and Virtualization team

Backups

Backup frequency and retention

VM disk tags determine Commvault backup frequency and data retention. For more, see Tags and levels of protection above.

Backups are configured to provide Intelligent Infrastructure clients with data protection and restoration as it pertains to business continuity. As such, the Commvault environment cannot be used for longterm data archiving or as a deep store for data.

Changing the backup schedule

Commvault does not have the means for clients to run off-schedule backups for a particular VM or groups of VMs. If you wish to protect your VM prior to a change, use the snapshot capabilities available through VMware.

Because of the way Commvault backups work, UITS cannot change the backup schedule for an individual VM. It is important to note that because Commvault does not use client resources to perform backups, it does not impact VMs the way most traditional backups can.

Backups for physical servers

At this time, only VMs that live within the Intelligent Infrastructure are eligible for Commvault backups.

Getting help

Identifying your VM tags

For help finding which tag was applied to your VM, see Determine the type of data protection used for your Intelligent Infrastructure virtual machines .

Changing your VM tags

To change VM tags, log into the II Self-Service portal; see Log into vRealize Automation (vRA) in Intelligent Infrastructure. Under Items > Machines, select the desired VM. Then under "Actions", select Change VM Backup Type.
