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 page appears.
Click 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 key to the right.
With CBT, backups only write blocks that have changed since the previous backup. 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 collect file and folder information during streaming backups, move the Collect file details toggle key to the right.
To enable file indexing, move the File Indexing toggle key to the right.
When you enable file indexing, if the MediaAgent associated with the backup plan or storage policy that is assigned to back up the VM group does not have the software packages that are required for file indexing, Commvault automatically installs those packages.
When you enable file indexing, if the access node (VSA proxy) that is assigned to back up the VM group does not have the software packages that are required for file indexing, Commvault automatically installs those packages.
Collect File and File Indexing options are mutually exclusive, but file indexing always takes precedence.
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 the type of backup to perform:
Application Aware: Uses in-guest application plug-ins to assist the Virtual Server Agent in quiescing the file system and applications and supporting granular application data recovery.
To specify credentials for guest VMs in the VM group, click the key button (), and then provide the guest credentials.
File system and application consistent: Quiesces the file system and applications while performing the backup.
Crash-consistent: Takes a point-in-time snapshot of virtual machine data without quiescing.
