I can get you all of the scripts I use if you like.

I actually just name them with a time/date as part of the directory
name.   Then I am able to just pick one to delete based on the oldest,
or not delete if i choose.   I can easily turn off deletions to allow
the backlog to grow, or leave it on to keep the same number of backups.

Additionally, I make a copy using hard links (recursive) to make it so
that only modified files are overwritten.   I end up with backups that
look like the whole file system as on any backup, but only take the
space of an incremental.
