Backup Operations for vCloud

Commvault backs up all of the virtual machines identified on the Content tab for a subclient, including virtual machines deployed in Azure Stack.

When a virtual machine is discovered during backup, a client for the VM is created in the CommCell Console if one does not already exist. If a virtual machine with spaces or special characters in its name is discovered during backup, the spaces or special characters are replaced with underscores ('_') when creating the VM client name that is displayed in the CommCell Console. The VM name with spaces or special characters is still displayed on the Virtual Machine Status tab for the backup job, in the backup job summary, and in reports that include the VM name. The following special characters are replaced:

[ \ \ | ` ~ ! @ # $ % ^ & * + = < > ? , { } ( ) : ; ' \ " \ \ s / ]

What Gets Backed Up

The following items are included in backups:

  • Virtual machines (Windows and Linux, powered on or powered off)

  • VMDK files

  • Virtual RDMs

  • GPT or dynamic disk volumes

  • vSphere tags on virtual machines (only with streaming backups)

  • Fault tolerant virtual machines that meet the following requirements:

    • Configured as fault tolerant in the vSphere Web client

    • Hosted on ESX 6.x or later

    • VM hardware version 11 or later

What Does Not Get Backed Up

The following items are not included in backups:

  • Virtual machines containing SCSI adapters that are configured for bus sharing (physical or virtual)

  • Virtual machines configured with fault tolerance (prior to ESX 6.x or hardware version 11)

  • Virtual machines with no disks attached

  • Physical RDMs

  • Independent disks

Backup Failures

  • Backup or restore can fail if the name of the datastore, cluster, or virtual machine contains any of the following characters: 

    + & @ % = # % * $ # ! \ / : * ? " < > | ; '

    For more information, see Error downloading or uploading virtual machine configuration file.

  • If some parts of a virtual machine backup job are not completed successfully, the job status is "Completed w/ one or more errors." You can view the Job Details dialog box and select the Virtual Machine Status tab to check the status of specific VMs.

    If the status for a specific virtual machine is "Partial Success," some information for the VM was successfully backed up, but other information was not. Failed items for a VM contribute to the Failed Objects count in the Backup Job Summary Report.

    A VM is only included in a backup of failed VMs if the VM is marked as Failed in the Virtual Machine Status tab. VMs that complete with partial success are not included as failed VMs.
