Works fine, EXCEPT on multi-tape dumps, where there are two problems: 1) rdump doesn't wait for the 2nd tape to be loaded. Hence, the end of the first tape contains the start of tape2 which runs into physical EOT without a double EOF written on the tape. This is sure to lock up your tape drive if you ever read this tape into the EOT. 2) After the write error when hitting EOT, loading a new tape on on the remote tape server works as expected UNTIL you try to restore from this tape and get the message: "Not a dump tape". Don't panic. For some reason rdump started the 2nd (and any subsequent tapes) with an EOF! So, tapes 2,3,... start out with an empty file before the dump file. Do an `mt fsf 1' before restoring from them. This is the command I use to back up to a Sun-3's 9-track mag tape: rdump 0udsf 6250 2300 backup@sunset:/dev/nrmt8 The account backup must exist and have a .rhosts' entry for root@yourNeXT.
