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

```bash
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)

    Trigger: Mon 2024-04-15 03:03:22 AEST; 18h left

Checking snapshots

```bash
truxnell@daedalus ~ [3]> sudo restic-lidarr-local snapshots
repository a2847581 opened (version 2, compression level auto)

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

```bash
truxnell@daedalus ~ [1]> sudo restic-lidarr-local restore --target /tmp/lidarr/ latest
repository a2847581 opened (version 2, compression level auto)
[0:00] 100.00%  2 / 2 index files loaded
