.. code-block:: console
$ restic -r /srv/restic-repo dump latest production.sql | mysql
If you have saved multiple different things into the same repo, the ``latest``
snapshot may not be the right one. For example, consider the following
snapshots in a repo:
.. code-block:: console
$ restic -r /srv/restic-repo snapshots

Here, restic would resolve ``latest`` to the snapshot ``1541acae``, which does
not contain the file we'd like to print at all (``production.sql``). In this
case, you can pass restic the snapshot ID of the snapshot you like to restore:
.. code-block:: console
$ restic -r /srv/restic-repo dump 098db9d5 production.sql | mysql
Or you can pass restic a path that should be used for selecting the latest
snapshot. The path must match the patch printed in the "Directory" column,
e.g.:
.. code-block:: console
$ restic -r /srv/restic-repo dump --path /production.sql latest production.sql | mysql
