I posted the request for help on 8mm multiple filesystem backups a while back. Here are some helpful responses I received. I implemented a different method, which is probably not as efficient as the multiple filesystem method. I use the command: find /local /u/ugrad /u/faculty /u/grad /u/staff /usr /etc -print | backup -i -q -f/dev/rmt1 This works ok and puts everything on one tape so the backup could be automated. I hope to change this to the multiple filesystem method when I get a free second.

The restore command defaults to the SECOND backup on the tape (don't ask me WHY!). That made us think that the first one was being overwritten by the second. Try something like: restore -s 1 ... to read the first backup on the tape. This was explained to us by an IBM person in Austin.

I believe the message from backup about rewinding the tape is in error. I get it too, but I have been able to skip out and read all of the backups. Try reading the tape with "restore -i -s1 -f/dev/rmt1.1". You should see the files from the first backup. "quit" and repeat the command and you should see the files from the second backup. You'll probably find the dumps are there. - Jeff Stewart Purdue University Computing Center
