Inspect the tapelist at your /build/path/etc/amanda/DailySet1/, usually /usr/local/etc/amanda/, something went agaga. It sounds as if there are only 2 entries, where there should be 5. Amlabel originates that file, and amdump shuffles the list as they are used. >I suspect that part of my problem (probably a large part) is conceptual. >We have plenty of tape and processing time and I was looking for a full >backup on each amdump execution.

Back to my original question: How do >define the sequence tapes are to be used? If the system is not 'adjusted' by human hands :), the normal tape usage will be in the order they were labeled. I use a script that increments the tape number as they are being labeled when I need to restart the whole thing as I did about 60 days back due to a drive failure of the drive the vtapes I use were on. Any other problems should be found by an su amanda -c "amcheck DailySet1" where 'amanda' is the user who will run the backups. That user can be anyone, but should be a member of the group disk or backup, even bin for some distributions. Probably compiled in & fixed by RH if its rpm's. And my advise isn't going to be 100% spot on as I don't use the rpms. >Any suggestions would be greatly appreciated. > >TIA > >Regards, Hugh > >-- >Hugh E Cruickshank, Forward Software, www.forward-software.com -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
