I'd like to get some suggestions on a backup system for my home PC.
Currently I have two identical drives set up in RAID 1 mirroring, but I'm
looking to change this since it doesn't protect against my accidentally
deleting or screwing up a file.
I was thinking of just setting up a cron job to mirror one drive onto the
other every night, but I'd like to avoid copying all the unchanged files
every time, and it would be nice if I could store multiple revisions, as
space permits.
there was a talk about this at DC LUG some time ago. THey use hard links,
very smart idea. You'd have the whole tree cloned, say every hour (or whatever
you like), and use hard links. That way you can safely remove aged trees
and still have all the files you wanted.
Of course you'll need to prepare this backup disk in a special way, since
the inode density needs to be higher than the normal default (especially
if your backup frequency is high and/or you like to keep a lot of versions).
From the dclug website i recalled this:

Does anyone know of some good software to do this? It almost seems like it
could be done with something like subversion, though I don't think you can
delete old revisions from an svn repository very easily.
right! that would be against the law!
