Editing VM Group Options for Hyper-V

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

Procedure

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

    The Hypervisors page appears.

  2. Click the name of the hypervisor that hosts the virtual machines.

    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 virtual machines 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.

      For Hyper-V, CBT is only available for Hyper-V Server 2012 R2 and later.

    • 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.
    • Collect file details: Select this option to collect file and folder information during streaming backups or when creating a backup copy from IntelliSnap backups. Use this option when creating a copy for tape storage, because file and folder information is required when recovering files from tape.
    • Collect file details for snapshot copy: Select this option to collect file and folder information when creating a snapshot copy from IntelliSnap backups. Use this option when creating a copy for tape storage, because file and folder information is required when recovering files from tape.

      Note: Collecting file details increases the time required to perform backups, and is not required to enable recovery of guest files and folders.

  6. Click Save.
