I understand that a restartable multi-tape version of dump has been
written at UC Berkeley.  It works as follows:
 
When dump reaches the end of a tape, it forks.  The parent waits,
and the child tries writing the new tape.  If the child fails for
some reason, the parent just reforks and tries again.  If the child
succeeds in writing the tape, it kills the parent and becomes the
new dump.  It seems as though this should be fairly easy to implement.
