Hi all
Sometimes I really don't understand the behaviour of backupexec (8.6). Following configuration:
Application Defaults:
- Media overwrite protection level: None
- Media overwrite options: Overwrite recyclable media contained in the targeted media set before overwriting scratch media
Job Definitions:
- Full Backup: Overwrite Media / Media Set: Full
- Diff-Monday to Diff-Thursday: Append to media, overwrite if no appendable media is available / Media Set: 4 Media Sets, from monday to thursday with only one tape.
My device is an hp storageworks 1/8 autoloader. Last week, I inserted a new tape, inventorized the library, saw the new tape and named it "w4m4". Because it is a tape which belongs to the full media set, after labeling, I moved it from Scratch Media to the corresponding backup-set "Full". Today is monday, so I've taken a look if the full job has been running, and it did run, but backupexec has chosen a wrong tape. There was an alert "Overwriting allocated media Diff-Mo", which doesn't belong to the Full Media-Set, it belongs to the Diff-Mo media set.
I really don't know why backupexec doesn't use the media contained in the media set Full! This isn't the first time something like this happens, and the choosing process doesn't follow a specific pattern, it chooses tapes from various media sets for writing the full backup.
Has anybody got an idea?
Thank you in advance: Marco
