+### Automatic Periodic Backups
+
+You can additionally set the `SCHEDULE` environment variable like `-e SCHEDULE="@daily"` to run the backup automatically.
+
+More information about the scheduling can be found [here](http://godoc.org/github.com/robfig/cron#hdr-Predefined_schedules).
+
+Folders daily, weekly and monthly are created and populated using hard links to save disk space.
