If argue that if you care enough about the content that you'll do more than say "oh well" to yourself if it becomes inaccessible, then researching this sort of thing or (probably easier but maybe more costly in terms of bandwidth use) rigging it up to your existing backup infrastructure is the minimum effort you did make. If you don't you have no high ground from which to complain or blame others from if it going away inconveniences yourself.

If you don't care about it that much, why do you keep it anyway?
