NOTE (2025-02-08)

I've since moved the tutorial over to my website. Clarified some of the wording, added exercises at the end, added links to useful resources.

For historical reasons, I'm keeping the original text here. But if you've just stumbled upon this tutorial for the first time, you may want to check out the revised version!

restic systemd configuration

1. sudo install -Dm644 restic@.service /etc/systemd/system/.
2. For each target:
   • Place the options (exclude, etc) and paths in the variable BACKUP_OPTIONS="..." in /etc/restic/TARGET/config. Newlines can be escaped with backslashes.
   • Place the repository path in /etc/restic/TARGET/repository.
   • Place the repository password in /etc/restic/TARGET/password.
3. To run the backups on a schedule, create a .timer file in /etc/systemd/system/ based on restic.timer.example, set the schedule and target unit, then systemctl enable --now whatever.timer.
4. To run the backups manually, just systemctl start it.
