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 plan. There are no substitutes for data backup to face any disasters where data may be at risk. As much as backup is important, the ability to restore is also equally important, since backup files will not mean anything if restore is not possible in the time of need. Although Proxmox does not provide everything you need for backup such as a granular file backup, backing up a virtual machine is very helpful. 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 of an up-to-date Proxmox cluster and how to apply new releases or patches regularly.
