Managing Remotes
================

.. _backup_remote:

:term:`Remote`
--------------

A remote refers to a separate Proxmox Backup Server installation and a user on that
installation, from which you can `sync` datastores to a local datastore with a
`Sync Job`. You can configure remotes in the web interface, under **Configuration
-> Remotes**. Alternatively, you can use the ``remote`` subcommand. The
configuration information for remotes is stored in the file
``/etc/proxmox-backup/remote.cfg``.

  :alt: Add a remote

To add a remote, you need its hostname or IP, a userid and password on the
remote, and its certificate fingerprint. To get the fingerprint, use the
``proxmox-backup-manager cert info`` command on the remote, or navigate to
**Dashboard** in the remote's web interface and select **Show Fingerprint**.

.. code-block:: console

  # proxmox-backup-manager cert info |grep Fingerprint
  Fingerprint (sha256): 64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe

Using the information specified above, you can add a remote from the **Remotes**
configuration panel, or by using the command:

.. code-block:: console

  # proxmox-backup-manager remote create pbs2 --host pbs2.mydomain.example --userid sync@pam --password 'SECRET' --fingerprint 64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe

Use the ``list``, ``show``, ``update``, ``remove`` subcommands of
``proxmox-backup-manager remote`` to manage your remotes:

.. code-block:: console

  # proxmox-backup-manager remote update pbs2 --host pbs2.example
  # proxmox-backup-manager remote list
  ┌──────┬──────────────┬──────────┬───────────────────────────────────────────┬─────────┐

  # proxmox-backup-manager remote remove pbs2


.. _syncjobs:

Sync Jobs
---------

.. image:: images/screenshots/pbs-gui-syncjob-add.png
  :align: right
  :alt: Add a Sync Job

Sync jobs are configured to pull the contents of a datastore on a **Remote** to
a local datastore. You can manage sync jobs in the web interface, from the
**Sync Jobs** tab of the datastore which you'd like to set one up for, or using
the ``proxmox-backup-manager sync-job`` command.  The configuration information
for sync jobs is stored at ``/etc/proxmox-backup/sync.cfg``. To create a new
sync job, click the add button in the GUI, or use the ``create`` subcommand.
After creating a sync job, you can either start it manually from the GUI or
provide it with a schedule (see :ref:`calendar-event-scheduling`) to run regularly.

.. code-block:: console

  # proxmox-backup-manager sync-job create pbs2-local --remote pbs2 --remote-store local --store local --schedule 'Wed 02:30'
  # proxmox-backup-manager sync-job update pbs2-local --comment 'offsite'
  # proxmox-backup-manager sync-job list
  ┌────────────┬───────┬────────┬──────────────┬───────────┬─────────┐
  │ id         │ store │ remote │ remote-store │ schedule  │ comment │
  ╞════════════╪═══════╪════════╪══════════════╪═══════════╪═════════╡

  └────────────┴───────┴────────┴──────────────┴───────────┴─────────┘
  # proxmox-backup-manager sync-job remove pbs2-local

For setting up sync jobs, the configuring user needs the following permissions:

#. ``Remote.Read`` on the ``/remote/{remote}/{remote-store}`` path
#. at least ``Datastore.Backup`` on the local target datastore (``/datastore/{store}``)

If the ``remove-vanished`` option is set, ``Datastore.Prune`` is required on
the local datastore as well. If the ``owner`` option is not set (defaulting to
``root@pam``) or set to something other than the configuring user,
``Datastore.Modify`` is required as well.

.. note:: A sync job can only sync backup groups that the configured remote's
  user/API token can read. If a remote is configured with a user/API token that
  only has ``Datastore.Backup`` privileges, only the limited set of accessible
  snapshots owned by that user/API token can be synced.
