Introduction
The Proxmox VE comes equipped with a robust backup and restore system to ensure data safety of virtual machines in a cluster. A good backup and restore system is mandatory for any sound disaster planning strategy. It is not matter of if, but when a disaster strikes, we must have the ability to restore virtual machines from as much of a latest backup as possible. A disaster can include a wide variety of situations, such as hardware failure, environmental damage, accidental deletions, misconfigurations, or anything else of this nature.
In a virtual environment, the importance of a sound backup/restore strategy is even higher. Since VMs are created and discarded frequently, without a proper strategy, a backup can quickly go out of control. A restore plan is also equally important since a backup is useless if we cannot restore in a timely and proper manner after a disaster.
