We've got an Exchange differential back-up set up to run (almost) every night (done with policies) and duplicate it to tape after it's done. The back-up itself runs fine, but since the start of the week the duplicates are failing with the following messages:
V-79-57344-33029 - Error - Mount failed.
Invalid Physical Volume Library Media Identifier.
V-79-57344-33029 - Unable to acquire device for the specified pool and media
Invalid Physical Volume Library Media Identifier.Before this week it succeeded every night. Nothing has changed in our configuration, not in Backup Exec or the hardware.
We've been able to duplicate it manually.. some of the times.
The back-up of the day before yesterday was impossible to get on tape, but when I manually ran another differential and manually duplicated that it worked. And today I could manually duplicate the policy created differential whilst the generated duplicate failed.
We really hope you can solve this.
Also, we can't duplicate incremental GRT Exchange back-ups to tape. But that seems to be a known issue.
