# Editing VM Group Settings for Oracle VM

For an existing VM group, you can modify options that affect backups.

## Procedure

1. From the Command Center navigation pane, go to Protect > Virtual machines.

   The Overview page appears.

2. Click the VM groups tab.

   The VM group page appears. The VM groups area displays summary information for any existing VM groups.

3. Click a VM group.

   The VM group details page appears.

4. On the Configuration tab, the Options area shows settings that are used to back up the instances in the VM group.

5. In the Options area, click Edit.

6. In the Edit options dialog box, 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.

     - Application Based: Performs application discovery for those VMs selected within the VM group and configures backups by installing an in-guest application agent.

     - To specify credentials for guest VMs in the VM group, click the key button (), and then provide the guest credentials

   - Datastore freespace required: Type the percentage of free space that should be available on the datastore before performing the backup.

7. To modify the backup 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 created in Command Center or a storage policy created in CommCell Console. You cannot change that selection for an existing VM group, but you can select a different backup plan or policy:

   - When editing the Plan setting, you can select a backup plan that was previously defined in Command Center.

   - When editing the Policies setting:

     - From the Storage policy list, you can select a storage policy that was previously defined in CommCell Console or a plbackup planan that was defined in Command Center.

     - Optional: You can select a schedule policy that was previously defined using CommCell Console.
