Just how often have -you- needed tape backups? The first time I've
-needed- tape backups besides today (from which I recovered due to fast
fingers and a thorough knowledge of what files I needed to reconstruct--in
less than an hour. The -last- time I needed a tape drive for real was in
about 1998. Once every six years. Ain't worth it to me.
Like I said, everything I do that's -truly- important is multi-homed
anyway. I may have it on Cobalt, but it's also on IgLou's shell server,
and they have Network Appliance RAID, complete with hourly snapshots 9
times a day. And they make tape backups daily.

Quicken fits quite nicely on a CD, much less a DVD. We use CDRW's.

Crashes are never good. :)

All of my essential data is so small that a simple rsync propogation or
burn to a single CDRW will do it.
As it is, since I got turned on to rsync, I've thought it's the next best
thing since sliced bread. I love it. Except when I accidentally put a /
on the end of something that I -didn't- want the / on. That's actually
dangerous. I'm thinking they should have made the behaviour a switch, not
relied upon syntactical typing of your data source path. Of anything in
rsync, that's -the- most likely thing to bite someone, IMHO.
