h1. Borg backups
This is documentation and scripts for using Borg backups with backupninja. This relies heavily on the work of "Jon Goldberg":https://github.com/PalanteJon, "Benzhaomin":https://0xacab.org/Benzhaomin, and "Guillaume Subiron":https://github.com/maethor.
h2. Usage
Main borg docs: https://borgbackup.readthedocs.io/en/stable/
List backups
<pre>
borg list /path/to/repo
</pre>
Mount a single backup
<pre>
borg mount /path/to/repo::individual_backup /tmp/mymountpoint
</pre>
Check viability of the repo
<pre>
borg check -v /path/to/repo
</pre>
If the backup has a passphrase, you'll need to enter it to do any of those commands. The passphrase should be in the client credentials, and will be in the /etc/backup.d/ jobs
h2. Setup
Install necessary packages, currently the best way to do that is by using jessie-backports.
<pre>
aptitude -t jessie-backports install python3-msgpack borgbackup
</pre>
The files borg, borglocal, borg.helper, and borglocal.helper should be placed in /usr/share/backupninja, permissions 644, owned by root:root.
<pre>
cd /usr/share/backupninja
wget https://hq.palantetech.coop/attachments/download/7133/borg && wget https://hq.palantetech.coop/attachments/download/7135/borg.helper && wget https://hq.palantetech.coop/attachments/download/7136/borglocal && wget https://hq.palantetech.coop/attachments/download/7134/borglocal.helper
chown root:root borg* && chmod 644 borg*
</pre>
The files 70-76 are example backupninja jobs, which would go in /etc/backup.d, permissions 600, owned by root:root.
<pre>
cd /etc/backup.d
wget https://hq.palantetech.coop/attachments/download/7130/70-local.borglocal
wget https://hq.palantetech.coop/attachments/download/7132/71-mfpl.borg
wget https://hq.palantetech.coop/attachments/download/7138/75-borglocalbackupcheck.sh
wget https://hq.palantetech.coop/attachments/download/7137/76-borgbackupcheck.sh
chown root:root 7* && chmod 600 7*
</pre>
Job 70 is for backing up to a usb drive, which will be mounted at the beginning of every job and unmounted at the end.
Necessary variables to change: device uuid, filesystem type, included and excluded files, directory to mount the usb drive to, passphrase
Job 71 is for backing up to either a local folder or a folder accessible by ssh on a remote host.
Necessary variables to change: included and excluded files, directory to put the backups in, host, ssh user, passphrase
Jobs 75 and 76 are for checking the viability of the job 70 and 71 backups respectively, and require coping over the variables from those jobs.
Please change the passphrase variable in these jobs to something other than "PASSPHRASE", or leave it empty, which will turn off encryption.
