Introduction
Microsoft provides a VSS Writer for Hyper-V Server to enable an online backup of virtual machines. If a backup is started with SEP sesam, snapshots of the virtual machines are created and then the .vhd files as well as the already created snapshots are backed up.
System requirements
- Microsoft Hyper-V Server with active Hyper-V VSS Writer
- SEP sesam Client since Version 3.6.4.24
Backup procedure
Create a new backup task for the Hyper-V client which contains the virtual machines.
After starting the backup, Hyper-V automatically creates snapshots for every active virtual machine.
Then the backup task starts for the defined machines.
Restore procedure
In case of a restore the corresponding virtual machine must be turned off. Afterwards single volumes (.vhd files), snapshots or the whole virtual machine can be restored.
- Example Restore of a single volume:
