For an existing VM group, you can modify options that affect backups.
From the navigation pane, go to Protect > Virtualization.
The Virtual machines page appears.
On the Hypervisors tab, click the hypervisor.
The hypervisor page appears. The VM groups area displays summary information for any existing VM groups.
Click a VM group.
The VM group details page appears.
On the Configuration tab, the Settings area shows settings that are used to back up the virtual machines in the VM group.
In the Settings area, do the following:
To use changed block tracking (CBT) for backups, move the Use changed block tracking toggle to the right.
With CBT, backups only write blocks that have changed since the previous backup. You can use CBT with managed disks only. For virtual machines where there is a known issue with CBT, you can turn off CBT to run backups using the cyclic redundancy check (CRC) method instead.
To perform IntelliSnap backups, move the IntelliSnap toggle key to the right.
To discover VM owners during backups, move the Auto detect VM owner toggle switch to the right.
To edit other settings, in the Settings area, click Edit.
The Edit settings dialog box appears.
Provide the following information:
No. of readers: Set the number of readers to control how many parallel read operations can be launched during backups.
Virtual machine backup type: Select one of the following options:
File system and application consistent: An application consistent backup quiesces the file system and applications while performing the backup.
Crash consistent: A crash consistent backup takes a point-in-time snapshot of virtual machine data without quiescing.
To modify the plan or policy associated with the VM group, click Edit in the Plan area or the Policies area.
The name of the area depends on whether the VM group was defined to use a backup plan that was created in the Command Center or a storage policy that was created in the CommCell Console. You cannot change that selection for an existing VM group, but you can select a different plan or policy, as follows:
When editing the Plan setting, you can select a plan that was previously defined in the Command Center.
When editing the Policies setting, you can make the following changes:
From the Storage policy list, you can select a storage policy that was previously defined in the CommCell Console or a plan that was defined in the Command Center.
Optional: You can select a schedule policy that was previously defined in the CommCell Console.
