During the backup of any virtual machine, a snapshot of the virtual machine gets created on its datastore. If the datastore of any virtual machine does not have sufficient space for snapshots, the backup job completes with one or more errors. Before performing the backup, you can set a threshold of required free space. If a datastore does not have the required free space, the software does not back up the virtual machines residing in that datastore.
Follow the steps given below to set the threshold for free space on a datastore:
-
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.
-
Select Perform Datastore freespace check.
-
In the Datastore freespace required box, enter the threshold value. By default, the threshold is set to 10%.
-
Click OK.
When you perform the backup of a subclient, a virtual machine will be skipped from the backup if its datastore doesn't have the required free space. If a virtual machine has disks on multiple datastores, and if any one datastore doesn't have the required free space, the virtual machine will be skipped from the backup.
This threshold applies to datastores of all the virtual machines in a subclient.
