# 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

## Setup

``` sh
