Tape > is known to have 20+year longevity. I'd say that in my situation, if the data is not needed after 4-5 years we probably won't need it at all. It's just that we don't want to just wipe off a desktop machine clean without doing some amount of archiving. So I'm not worry about longevity. > > One thing to consider with regards to using compressed > images... they are intolerant of defects in the storage medium. Good point.

Thanks, although in my situation this does not really apply. The data is not that important, this is just a case where we wouldn't want to just wipe it off. > OTOH, if you have network capabilities to other computers located > at a distance, then archival over the network, using e.g. rsync, > is a very viable solution.

It'd be nice to be able to take every one or two month snapshot and put it in a more permanent medium. But I am not sure if I can do that easily and economically with about ~200GB data. RDB
