Performing VM backup in Microsoft’s Hyper-V virtual environment may not seem to be an easy task at first. If the backup process is not configured correctly, things could go wrong.
Regularly do nakivo hyper-v backup for your VMs according to the Recovery Point Objective and Recovery Time Objective values established within the framework of your business continuity plan. Backups should be performed on a regular, scheduled basis, rather than sporadically.
Maybe XenServer with Vinchin backup is more cost-effective. XenServer is also open-sourced.
