Minimalist restic backup with systemd.
This repository aims to provide simple and working example of how to run restic with systemd. There is no fancy notification, no complex installation scripts, just a few files easy to maintain and edit as required.
It is assumed that you know your way around both restic and systemd.
Install the systemd files with:
sudo make installInstall the configuration example with:
sudo make install-confWarning: this will overwrite any previous configuration!
The Makefile honors the DESTDIR environment variable so if you want to
install it somewhere else to test things out, just run:
DESTDIR=/tmp/test make installThe configuration is done by passing variables in /etc/restic/restic.conf to
restic as environment variables with systemd. Edit this file as needed.
Edit the timers in /etc/systemd/system/restic-*.timer to adjust the backup
frequency.
Edit the services in /etc/systemd/system/restic-*.service to change restic
arguments or clean up policy.
If your system is secure, you should also protect your backups. The sensitive
files installed by make install-conf are owned by root with mode 600.
Enable and start the timers
sudo systemctl enable --now restic-backup.timer
sudo systemctl enable --now restic-forget.timerVerify the status, e.g.
sudo systemctl list-timers
sudo systemctl status restic-backup.serviceFor ease of use I created a wrapper
script that will load the configuration before calling restic.
Then I just call sudo restic-wrapper.sh check.
I used inspiration from all over internet, so thank you internet! 🤝
