Try a new full backup with
dump -0aLuf /mnt/da0/backup-compaq.1.dump /
then for the incremental use
dump -1aLuf /mnt/da0/backup-compaq.1.dump /
The option you're missing is "u", but "L" is worth using as well when
you're backing up a mounted filesystem.
You could hack the contents of /etc/dumpdates to avoid having to repeat
the level zero dump if you know the date and time when the original one
was started.
