Backup is, and always has been, a central aspect of IT administration.
The need to recover from data loss is fundamental and only increases with
virtualization.

For this reason, we've been shipping a backup tool with Proxmox VE, from the
beginning. This tool is called ``vzdump`` and is able to make
consistent snapshots of running LXC containers and KVM virtual
machines.
But ``vzdump`` only allowed for full backups. While this is perfect

In July 2020 we released the first beta version of Proxmox Backup
Server, followed by a first stable version in November 2020. With the
support of incremental, fully deduplicated backups, Proxmox Backup
significantly reduces the network load and saves valuable storage
space.
