Backing up a windows server using agent to disk (B2D) works flawlessly for weeks, now starts throwing error:

 

Failed Final error: 0xe00084cf - Unknown error. Final error category: Job Errors 

 

Verify
Media mount failed.
User canceled a Physical Volume Library operation.

WHY? I've checked media, removed media, used new media, and still the same issue.

 

PLEASE HELP! -THX Bart

How about some very specific details about your setup? BE version, server version, 32 or 64-bit, what hardware are you backing up to, how is it connected? remote agent or local? what other agents are you using? Any errors in your Application/System log?

 

Off the top of my head, I am thinking you have bad hardware somewhere. I would run all available hardware diagnostic programs for your server, B2D drive, and SCSI card (if applicable).

Disk is full perhaps?  Check the properties on the B2D under Devices - verify everything is as it should be :)

Sure, no problem thanks for taking an interest guys-

 

Details about the setup:

  • BE Version 12.0 Rev 1364
  • Server is 32bit
  • I’m backing up to a B2D folder on a remote hard drive hosted on an Idealstor removeable hard-drive server running 32bit windows 2003 std.  Sounds fancy, but it’s all over standard windows filesharing (i.e. \\server\h$\BackupExec...)
  • Using Remote agent with file open option
  • I’m not seeing any errors in the app or sys logs except for the usual log by backup exec that the job failed - “unknown error”
  • Disk has 139 of 931GB available.  Each backup is about 70GB

 

What really gets me is this was working flawlessly for some time, now it’s bust.  I switched the backups to point to our NAS (instead of the Idealstor) and that was working for a couple weeks, now that’s broken.  What is this thing tripping up on?  Is there a way to get a more granular error to troubleshoot?  I can't tell if the problem lies at the backup server, source server, media or somewhere inbetween.

Please read this post that I solved over the weekend.

The problem is not the same, but the set up is similar and may point you in the right direction regarding removable drives. I am not sure if you set up the B2D as a removable one, but you might want to change it to nonremovable and keep in mind the one drive, one letter, one B2D folder concept.

 

I may have other ideas, but please try this first.
