Backup Guide
|
||
============
|
||
|
||
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 :option:`mailserver.storage.path`. 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 :option:`mailserver.storage.owner`, and :option:`mailserver.storage.group`).
|
||
|
||
To backup spam and ham training data, backup ``/var/lib/redis-rspamd``.
|
||
|
||
Finally you can (optionally) make a backup of ``/var/dkim`` (or whatever you
|
||
specified as :option:`mailserver.dkim.keyDirectory`). If you should lose those
|
||
don’t worry, new ones will be created on the fly. But you will need to update
|
||
the DKIM TXT records to reflect the new key material.
