File State Backups
|
|
==================
|
|
|
|
In 0.10.2 a new feature was added for backing up files that are replaced by
|
|
the file.managed and file.recurse states. The new feature is called the backup
|
|
mode. Setting the backup mode is easy, but it can be set in a number of
|
|
places.
|
|
|
|
The backup_mode can be set in the minion config file:
|
|
|
|
.. code-block:: yaml
|
|
|
|
backup_mode: minion
|
|
|
|
Or it can be set for each file:
|
|
|
|
.. code-block:: yaml
|
|
|
|
/etc/ssh/sshd_config:
|
|
file.managed:
|
|
- source: salt://ssh/sshd_config
|
|
- backup: minion
|
|
|
|
Backed-up Files
|
|
===============
|
|
|
|
The files will be saved in the minion cachedir under the directory named
|
|
``file_backup``. The files will be in the location relative to where they
|
|
were under the root filesystem and be appended with a timestamp. This should
|
|
make them easy to browse.
|
|
|
|
Interacting with Backups
|
|
========================
|
|
|
|
Starting with version 0.17.0, it will be possible to list, restore, and delete
|
|
previously-created backups.
|
|
|
|
Listing
|
|
-------
|
|
|
|
The backups for a given file can be listed using :mod:`file.list_backups
|
|
<salt.modules.file.list_backups>`:
|
|
|
|
.. code-block:: bash
|
|
|
|
# salt foo.bar.com file.list_backups /tmp/foo.txt
|
|
foo.bar.com:
|

Restoring
|
|
---------
|
|
|
|
Restoring is easy using :mod:`file.restore_backup
|
|
<salt.modules.file.restore_backup>`, just pass the path and the numeric id
|
|
found with :mod:`file.list_backups <salt.modules.file.list_backups>`:
|
|
|
|
.. code-block:: bash
|
|
|
|
# salt foo.bar.com file.restore_backup /tmp/foo.txt 1
|
|
foo.bar.com:
|
|
----------
|
|
comment:

Successfully restored /var/cache/salt/minion/file_backup/tmp/foo.txt_Sat_Jul_27_17:48:28_369804_2013 to /tmp/foo.txt
|
|
result:
|
|
True
|
|
|
|
The existing file will be backed up, just in case, as can be seen if
|
|
:mod:`file.list_backups <salt.modules.file.list_backups>` is run again:
|
|
|
|
.. code-block:: bash
|
|
|
|
# salt foo.bar.com file.list_backups /tmp/foo.txt
|
|
foo.bar.com:
|
|

.. note::
|
|
Since no state is being run, restoring a file will not trigger any watches
|
|
for the file. So, if you are restoring a config file for a service, it will
|
|
likely still be necessary to run a ``service.restart``.
|
|
|
|
Deleting
|
|
--------
|
|
|
|
Deleting backups can be done using :mod:`file.delete_backup
|
|
<salt.modules.file.delete_backup>`:
|
|
|
|
.. code-block:: bash
|
|
|
|
# salt foo.bar.com file.delete_backup /tmp/foo.txt 0
|
|
foo.bar.com:
