A Complete Backup Guide
|
|||
|
|
=======================
|
|||
|
|
|
|||
|
|
This is really easy. First off you should have a backup of your
|
|||
|
|
``configuration.nix`` file where you have the server config (but that is
|
|||
|
|
already in a git repository right?)
|
|||
|
|
|
|||
|
|
Next you need to backup ``/var/vmail`` or whatever you have specified
|
|||
|
|
for the option ``mailDirectory``. This is where all the mails reside.
|
|||
|
|
Good options are a cron job with ``rsync`` or ``scp``. But really
|
|||
|
|
anything works, as it is simply a folder with plenty of files in it. If
|
|||
|
|
your backup solution does not preserve the owner of the files don’t
|
|||
|
|
forget to ``chown`` them to ``virtualMail:virtualMail`` if you copy them
|
|||
|
|
back (or whatever you specified as ``vmailUserName``, and
|
|||
|
|
``vmailGoupName``).
|
|||
|
|
|
|||
|
|
Finally you can (optionally) make a backup of ``/var/dkim`` (or whatever
|
|||
|
|
you specified as ``dkimKeyDirectory``). If you should lose those don’t
|
|||
|
|
worry, new ones will be created on the fly. But you will need to repeat
|
|||
|
|
step ``B)5`` and correct all the ``dkim`` keys.
