:title: Storage: Proxmox Backup Server
endif::wiki[]

Storage pool type: `pbs`

This backend allows direct integration of a Proxmox Backup Server into {pve}
like any other storage.
A Proxmox Backup storage can be added directly through the {pve} API, CLI or
the webinterface.

Configuration
~~~~~~~~~~~~~

The backend supports all common storage properties, except the shared flag,
which is always set. Additionally, the following special properties to Proxmox
Backup Server are available:

server::

Server IP or DNS name. Required.

username::

The username for the Proxmox Backup Server storage. Required.

TIP: Do not forget to add the realm to the username. For example, `root@pam` or
`archiver@pbs`.

password::

The user password. The value will be saved in a file under
`/etc/pve/priv/storage/<STORAGE-ID>.pw` with access restricted to the root
user. Required.

datastore::

The ID of the Proxmox Backup Server datastore to use. Required.

fingerprint::

The fingerprint of the Proxmox Backup Server API TLS certificate. You can get
it in the Servers Dashboard or using the `proxmox-backup-manager cert info`
command. Required for self-signed certificates or any other one where the host
does not trusts the servers CA.

encryption-key::

A key to encrypt the backup data from the client side. Currently only
non-password protected (no key derive function (kdf)) are supported. Will be
saved in a file under `/etc/pve/priv/storage/<STORAGE-ID>.enc` with access
restricted to the root user.  Use the magic value `autogen` to automatically
generate a new one using `proxmox-backup-client key create --kdf none <path>`.
Optional.

.Configuration Example (`/etc/pve/storage.cfg`)

Storage Features
~~~~~~~~~~~~~~~~

Proxmox Backup Server only supports backups, they can be block-level or
file-level based. {pve} uses block-level for virtual machines and file-level for
container.

Examples
~~~~~~~~

// TODO: FIXME: add once available
//You can get a list of exported CIFS shares with:
//
//----
//# pvesm scan pbs <server> [--username <username>] [--password]
//----

Then you could add this share as a storage to the whole {pve} cluster
with:

----
# pvesm add pbs <id> --server <server> --datastore <datastore> --username <username> --fingerprint 00:B4:... --password
