Question about backup (derpzilla.net)

Hey guys,

I would like to setup some backups.

I have a raspberry at home and 2 VPS’s. I’m trying to setup borgmatic on my raspberry to back it up and the 2 VPS’s but I’m not sure this can be done.

Right now I’m looking to back up the raspberry and use rclone to mount one of the VPS and back it up. The issue is with the second VPS, it has MariaDB running and I can’t see how to back it up remotely (the port is not exposed publicly). I don’t find anything about tunneling in borgmatic. Am I forced to install borgmatic on the VPS to back it up? If I do this, how can I merge the back up with the other ones?

Actually should I do this or have 3 separate borg repositories?

Lastly, my raspberry uses rclone to push to S3 and I don’t want the keys to be accessible on the VPS’s, that’s why I’m trying to have borgmatic only on my raspberry.

Thanks for your help!

Before using borg I would recommend you to take a look at restic. In my opinion it is better in everything than borg.

As for how to backup the database, my advice is to export the database to a SQL file and backup that file. That will always be easier than having to deal with agents that connect to the database.

As for the number of repositories, if you use restic, a single repository is enough. Besides, as restic does deduplication, if you have the same files between your machines, they will only occupy the space of one. ;-)

I hope I have helped you with some of my ideas.

Best regards.

Thanks, indeed, restic looks interesting!

For now I don’t have much use for the deduplication as every servers are hosting different data.

One drawback I can see is the memory usage. My raspberry only has 2GB I’m not sure if this is going to be an issue. Currently the data I need to back up are around 100GB.
