- 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?
