You can't append new data onto a cpio file on tape. Presuming that
the full backup if the first file on the tape, you want something
mt -f /dev/nrst0 fsf 1
cpio -o -v -F /dev/rst0 < incremental_file.list >& log.out
But you'll probably find it easier to use one tape per backup.

cpio, tar, pax - "De gustibus non est disputandum"
