Thanks, but wow, that seems unnecessarily complicated and
time-consuming.
I think I'll stop naming my back-ups with a time stamp and just use a
date stamp, and then in my back-up script (which I run once daily) I'll
use "date" to calculate a date x days in the past and delete that single
archive. Since this machine isn't on 24/7 I'll have to manually remove
archives once in a while, but that's preferable to the current
situation.
In the meantime I'll write a short, one-time script to loop through a
manually compiled list of old archives I want to delete to get to where
I want to be with my archives.
Thanks for your suggestion.
