+### Creating backups
 
-Run daily
+There is a `backup` command in `glamr-dev`. The backup is named after the current day of the week, so in effect there will be a maximum of 7 rotating backups. The backup command relies on two environment variables: `DOCKER_PATH` and `BACKUPS_DIR` - you need to set these in your `.env` if you plan to run backups manually, but if you are running it with a cron job (recommended) you need to set environment variables within the crontab itself. See more details below.
+
+### Restoring backups
+
+1. back up your VPS if possible (e.g. taking a snapshot)
+2. Locate the latest backup, or run the backup program: `./glamr-dev backup`
+3. copy database dump into the container: `docker cp ~/ausglamr.dump ausglamr-db-1:/tmp/`
+4. restore the dump: `docker exec -d ausglamr-db-1 pg_restore -c -e -U ausglamr -d ausglamr /tmp/ausglamr.dump`
+
+## Cron jobs
+
+The obvious way to run the management and backup commands is via cron jobs. It's important to note that environment variables generally need to be set within the crontab - you can't rely on passing them in from Ausglamr nor from a user context. If you forget to to this they will be blank and one of the bad things that will happen is cron will try and fail to run the Unix program `exec` instead of `docker exec` when trying to run backups.

+Below are suggested crontab settings and jobs for Ausglamr.
