Hear Hear,

Actually I did it once on a "soon-to-be-reinstalled" machine to see what would
happen. Machine and all daemons stayed running.. then I got bored, rebooted
and re-installed.

Hmmm,
For some reason (there must be a reason), I've adopted the following procedure.

Monthly -> Keep for 12 Months Pile
Then two Weekly tapes which get rotated each week, every once in a while I make
the weekly into a monthly and bring in a new weekly.

Weekly backup on Monday morning, grabs everything changed since last monthly,
tape gets spit out. New tape then for the rest of the week.

Ecrix VXA-1, Tape drive, and an embarrassingly primitive shell script.

It has to be said, I've been able to go back to a 12 month old tape and do a
restore (assuming of course I had actually backed up the data in the first
place.. but that's another story), it's never failed.
