- I did not try multiple Sybase dumps to tape, but I backup a set of
- workstations automatically: just use /dev/nrst0 instead of /dev/rst0
- (on a SUN) as the tape device name. the nrst0 does no rewind after
- the operation, so you should be able to put dumpfile after dump file.
- use the "mt -f /dev/nrst0 sta" to check. Or write your databases to
- files and put them those on tape
