   I use rsync. I set up an automatic system for one client which did backups   
   twice daily going back 14 days. With careful filtering of less important   
   files, it didn’t take up much more space than the original volume it was   
   backing up.   
      
   rsync has this need feature where you can do an incremental backup that   
   looks just like a full backup for restoration purposes. That is, it   
   dedupes files which haven’t changed since the previous backup.
