-----------------
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.

is enforced by {pve} and not the file-system, that means that a manual removal
of a backup file itself is still possible for anyone with write access to the
underlying backup storage.
NOTE: 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.
