14 Backup / Restore Microsoft Virtual Machines

This section describes in detail how to backup and restore virtual machine running on Microsoft Hyper-V Server with OBM.

The following steps are performed during a backup job:

Connection from the backup client to the backup server is established.
Download the server file list from the backup server.
Commands are issued to the hypervisor to create snapshot (memory dump) of the virtual machine with Volume Shadow Copy.

Important:
The corresponding virtual machine will be paused during the snapshot process, and resume when the snapshot is completed.

Do not attempt to start the virtual machine while it is in the saving state. The snapshot created may be invalid.

Furthermore, the corresponding virtual machine uptime will also be reset to 00:00:00 in the Hyper-V Manager.

After generating all files, the files are copied to the temporary spool path and upload to OBS.
Commands are issued to the hypervisor to remove the Volume Shadow Copy snapshot created.
Backup completed successfully.
