How much data do you have? How much if it is original source, and how
much is mechanically derived from it, or redownloadable (like all the
Debian packages)? For original source, consider a distributed
versin-control system, like monotone, and make sure a friend maintains a
copy of the repository. monotone synchronises repositories over the
network, which make sure if either of you have a copy of something, both
of you do. And ever if you discard the working copy of a file, it still
keeps it but marks it discarded, so you can undiscard it if you wish.
monotone is paranoid about data loss or corruption.
But if your data consists of things like entire three-hour
high-definition movies, it may not be as effective as I'd like.
Certainly you could use this in addition to another system. The more
completely different kinds of backup you have, the safer you'll be.
