Nightly Backups are facilitated by nixos restic module & a helper module ive written.

These run to my NAS 'local' and cloudflare R2 'remote'

They are a systemd timer/service so you can query or trigger a manual run with

truxnell@daedalus ~> systemctl status restic-backups-lidarr-local.timer
● restic-backups-lidarr-local.timer
     Loaded: loaded (/etc/systemd/system/restic-backups-lidarr-local.timer; enabled; preset: enabled)

Testing a restore (would do --target / for a real restore) Would just have to pause service, run restore, then re-start service.

truxnell@daedalus ~ [1]> sudo restic-lidarr-local restore --target /tmp/lidarr/ latest
