Backups via restic

The below commands will setup a local backup of your photo frame using restic.

Important Considerations

• restic can use a bit of memory, you'll want at least 2Gb of ram on your Raspberry Pi to use this setup
• This setup does NOT include photos as part of the backup to keep backup sizes down
• This seutp assumes you have cron setup and runs the backup at 0700 every day
