Years ago, I set up a backup tool that wrapped rsync. It has faithfully and 
reliably backed up a dozen hosts and too many TB of data to mention, offsite, 
automatically saving as many backup points as disk space allows. 
You're certainly welcome to try it!

It works on an "ascending powers" basis, EG: 

1 day ago, 
2 days ago, 
4 days ago, 
8 days ago, 
16 days ago... 
.... 
until out of disk space.
