> people who back up to cd/dvd can answer that :) My venti, which backs a fossil used by 70 student accounts, of which five are currently "active", fills arenas *very* slowly. I burn the newest arena to one of two CD-RW's every week or so, and when an arena fills I burn it and all the previous ones to CD-R (nobody knows how long CD-R's last, because by the time you can do a longevity study the dyes have all changed). At the end of most semesters I burn just the most recent arena to CD-R even though it's not full. Off-site I have a small stack of CD-R's, total cost maybe $5. The two CD-RW's set me back around $3 each, a couple years ago when they were more expensive. This wouldn't be fun for somebody generating lots of of new data, but then again I'm not hosting a Debian mirror, and this way I'd still have *something* even after a machine room flood or EMP event.
