Just to show you what rsync snapshots should look like here is a
really quick and dirty script that will make a complete backup then a
snapshot using most of the information from your scripts:

Note that it just makes 2 backups.  If you run it again it will make
another full and another snapshot with a 5 minute pause in between and
there is no error handling so please only consider this a very basic
