At my work, we backup on a daily basis. We use Backup Exec 10d for Windows Servers and a Dell Tapeunit (13 months old).
The last 5 weeks we have a problem with the tapes we use on Tuesday.
5 weeks ago I checked (on Wednesday) if the backup of the day before was finished, but the tape was out of the unit and the unit asked for a cleaning tape. So I ran the cleaningtape and the next backup finished properly.
The next Tuesday, the same problem occured. So I replaced the Tuesday-tape with a new one.
The next week, the same problem happened.
I have already tried 3 brand-new tapes for the Tuesday backup, but none worked.
Even in the Job Log there is nog message of a failure.
We use MS windows server 2003 and in that Eventlog, there is no message of a missing tape....
I don't think the problem lies in the unit itself, because the other backups are good with no errors.
Normally when a tape ejects it is because there is either:
1. No space available if you append to your tapes;
2. Tape is not in the scratch set and cannot be overwritten.
I'd go into your Overwrite Protection on your media sets and make sure they are all OK and correct, and then check to see whether or not your jobs are trying to append to the media or need to overwrite.
Craigs second question refered tp whether you moved the new tapes into the production medai set, or whether you just left them in the Scratch media set
if you moved them to the production media set, then they will be write protected until the OPP has expired. when you enter new tapes into your rotation, you need to label them and leave them in scratch. When backupExec uses them, it will move them into the media set they belong in
I think the media set is the place to took for overwrite protection and append period. Since you are using one tape all week, the append period on the media set the job is set up to use should be at least 4 days.
