By default, quiescing is enabled for VMware backups. Quiescing pauses or alters the state of running processes on a computer, especially those that might modify information stored on disk during a backup. Quiescing the operating system and applications helps to guarantee a consistent and usable backup that includes pending transactions.
Procedure
To disable quiescing before performing backups:
-
From the CommCell Console, navigate to Client Computers > virtualization_client > Virtual Server > VMware > backup_set.
-
Right-click a subclient and click Properties.
-
Click the Backup Options tab.
-
Under Virtual Machine Backup Type, select Crash Consistent.
-
Click OK.
When you perform the backup of the subclient, quiescing will not be performed on the virtual machines in the subclient.
