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 / ]

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.
