+Backup Protection
+-----------------
+
+You can mark a backup as `protected` to prevent its removal. Attempting to
+remove a protected backup via {pve}'s UI or API will fail. However, manual
+removal of a backup file via CLI is still possible. Protected backups are
+ignored by pruning and do not count towards the retention settings.
+
+For filesystem-based storages, the protection is implemented via a sentinel file
+`<backup-name>.protected`. For Proxmox Backup Server, it is handled on the
+server side.
