Yeah, thats pretty much the way I do that.

Its a bear though, when the machine in question needs a 
complete restore from tape... Between tcp wrappers, rsh being turned off
(by default) *and* living in /usr, etc, etc, it was an all day 
(ok, night) affair the last time I lost a drive (5 1/4", 9G Seagate, 
did NOT like the amt. of ventilation in that cabinet.)

Just out of curiosity, have you tried not using the rmt protocol, but
using rsh (or ssh) to copy the data over? Some work done at stanford
in the early nineties showed that rmt was *very* slow, and simply
doing "rsh <hostname> dump | dd <reblock it out to tape>" was
faster. I confirmed that result going to a disk buffer.
