I've started using rsnapshot. It does something similar with the local
retention, but each file which is identical (between retained backups)
is hard-linked rather than taking multiple disk blocks.

I set up the config file once (which took 2 attempts and maybe 2.5
hours in total), set up cron and it just runs.


The problem I find with hand-rolled backup scripts (which I've used in
the past) is that you're the one maintaining them...
