Actually, the tape was correctly written. The man pages on dump state that dumps
made with the dump supplied by Next are not compatible with restore programs from
other vendors. Supposedly the rdump.old in /usr/etc should work with restore programs
from other vendors but has not worked in my experience (which is limited). To restore
files from the dump tape on the sun use /etc/rrestore on the NeXT. To do this you have
to be root on the NeXT and have the NeXT included in the .rhosts file on the sun. 

By the way, how come the man pages state that rdump only works with other NeXT machines?
