In this chapter, we looked at the backup and restore features in Proxmox, how to configure them, and how to use them to create a good data disaster recovery plan. We also looked at the new VM replication feature to replicate a VM across nodes for safekeeping when using local storage.

There are no substitutes for backing up data in order to mitigate any disasters where data may be at risk. As much as backing up is important, the ability to restore is also equally important, since backup files will not mean anything if a restore is not possible in times of need. Although Proxmox does not provide everything you need for backing up, such as a granular file backup, the ability to back up a virtual machine is very helpful. The backup features in the Proxmox platform have proven to be reliable in production environments and during actual disaster scenarios.

In the next chapter, we are going to take a look at the necessity for an up-to-date Proxmox cluster and how to apply new releases or patches regularly.
