This has been plaguing me for days, and I can't figure it out. I'm hoping someone here can help. First, the vitals:
BE: 10d (10.1 Rev 5629) Service Pack 3
Windows: Server 2003 Standard SP2
Library: Quantum PX502
For the last several days, our daily backups have been getting delayed, if they start at all. Turns out it's because Backup Exec was waiting for overwritable media. No problem, I said. Reduced the retention times, added some tapes, and moved a couple into the Scratch Media pool.
But it's still happening. Came in this morning, and last night's backup was still waiting for overwritable media. However:
*) There are 2 overwritable tapes in the scratch media pool
*) There are 4 overwritable tapes in the media set associated with the job
*) There are 2 more overwritable tapes in other media sets
I've read the "How BE Selects Media" and "Understanding Media Sets" FAQs, and from what I can tell, by all rights BE *should* be seeing available media.
*) Media Overwrite Protection Level is set to Partial
*) Media Overwrite Options is set to "Overwrite recyclable media contained in the targeted media set before overwriting scratch media"
*) The targeted media set contains four available, overwritable tapes. All were allocated over 4 months ago. The media set has an overwrite protection period of 132 hours (5.5 days).
*) As mentioned, the scratch set contains two available, overwritable tapes
We have a different job that runs daily, a differential that appends to a tape, which has been running without a hitch. So I know the hardware's fine.
What the heck is going on?
