Create Backup Set

Backup Requirements

Please ensure that the following requirements are met by the Hyper-V server:

  1. Hyper-V server is installed on the this computer.
  2. The Hyper-V management tools are installed on the Hyper-V server.
  3. Consider increasing the JVM (Java Virtual Machine) memory allocation to improve performance of the backup operation.
  4. It is recommended that the temporary directory have disk space of at least 50% of the largest sized virtual machine to be backed up.
  5. For backup of virtual machine with snapshot, backup of the whole VM instead of individual disk is highly recommended.
  6. The current virtual hard disk specification limits the size of a virtual hard disk to be 2040 GB (2 TB), which can fit a volume of size 2040 GB minus 2 MB.

Limitations

The following are limitations of the MS Hyper-V backup module:

  1. Backup of virtual machine with pass through disk (directly attached physical disk) is not supported.
  2. For virtual machine with snapshot, the restoration process for individual virtual disk requires manual editing of VM configuration files.
    In-depth knowledge on Hyper-V is required.
  3. The virtual machine cannot start up if the guest operating system virtual disk is not restored.
  4. Restore of individual virtual disk to a different virtual machine is only supported for virtual disk with no snapshot.
  5. For backup of individual virtual disk, the restored virtual machine does not support the reversion of previous snapshots, if the snapshot contains disks which are not previously backed up by CloudBacko™.


Set the name of the backup set

Name This is the name of the backup set. You can create a meaningful name for it.
Backup Type Enter the correct backup type from the drop down box.
Version Version of the Hyper-V server.

To create a backup set name:

  1. Type in a meaningful backup set name.
  2. Enter correct backup type, eg: MS Hyper-V backup.
  3. Enter correct version of the Hyper-V Server.
