Editing VM Group Options for Oracle VM

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


  1. From the navigation pane, click Solutions > Virtualization > Hypervisors.

    The Hypervisors page appears.

  2. Click the name of the hypervisor that hosts the instances.

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

  3. Click the name of a VM group.

    The VM group details page appears.

    The Settings area shows settings that are used to back up the instances in the VM group.

  4. In the Settings area, click Edit.
  5. In the Edit options dialog box, provide the following information:
    • Use changed block tracking: Select this option to use changed block tracking (CBT) for backups.

      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.

    • No. of readers: Set the number of readers to control how many parallel read operations can be launched during backups.
    • Datastore freespace required: Type the percentage of free space that should be available on the datastore before performing the backup.
  6. Click Save.
