first off, use tcopy command to see how many files are already on the
tape, don't assume you know

tcopy /dev/rmt0

then use the FSF X parameter of tctl or tapeutil to position the tape
past the last file already on the tape (X=number of files already on
the tape)

don't forget when using the FSF command (or other similar commands)
to use /dev/rmt1.1 so your tape won't automatically rewind before
your new backup starts
