@ -213,13 +213,29 @@ On most Unixy shells, you can either quote or use backslashes. For example:
|
||||
|
||||
By specifying the option ``--one-file-system`` you can instruct restic
|
||||
to only backup files from the file systems the initially specified files
|
||||
or directories reside on. For example, calling restic like this won't
|
||||
backup ``/sys`` or ``/dev`` on a Linux system:
|
||||
or directories reside on. In other words, it will prevent restic from crossing
|
||||
filesystem boundaries when performing a backup.
|
||||
|
||||
For example, if you backup ``/`` with this option and you have external
|
||||
media mounted under ``/media/usb`` then restic will not back up ``/media/usb``
|
||||
at all because this is a different filesystem than ``/``. Virtual filesystems
|
||||
such as ``/proc`` are also considered different and thereby excluded when
|
||||
using ``--one-file-system``:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ restic -r /srv/restic-repo backup --one-file-system /
|
||||
|
||||
Please note that this does not prevent you from specifying multiple filesystems
|
||||
on the command line, e.g:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ restic -r /srv/restic-repo backup --one-file-system / /media/usb
|
||||
|
||||
will back up both the ``/`` and ``/media/usb`` filesystems, but will not
|
||||
include other filesystems like ``/sys`` and ``/proc``.
|
||||
|
||||
.. note:: ``--one-file-system`` is currently unsupported on Windows, and will
|
||||
cause the backup to immediately fail with an error.
