Issue



GRT Backup of Exchange 2010 or 2007 may stop processing in random instances of the job and at different stage and halt with a Loading Media prompt. This can happen if it is just this job running or several other jobs running at the same time.

Backup has to be cancelled eventually and fails with out of space errors.


Error



The backup-to-disk folder that was specified for this job ran out of disk space. The backup set has been deleted, and the backup-to-disk folder has been paused.

Either free some disk space, or specify a different backup-to-disk folder for the job. Before other jobs can use this folder, you must clear the Pause state. On the Devices view, right-click the folder and click Pause to remove the check mark.

 


Environment



Backup Exec versions 2010 and 2012

Exchange versions 2007 and 2010


Cause



From SGMon on the media server during backup time, the following can be observed when the windows WriteFile function attempts to access the storage media during the GRT reclamation:

BENGINE:  [01/22/14 13:52:31] [18512]     2014-01-22T13:52:31.541 [server]             - Updating session {f0cbd72c-9599-4694-bff5-d95951ce85ff} with drive Iomega NAS {0cf7b1d8-aa7c-4ab5-951a-08b79d5b3aa0}.1

Alternately, WriteFile can return other error codes such as:

[5684] 01/31/14 09:39:14 [ndmp\loops]         - HandlePDIOutofSpace: Last error was 0x00000299.


Solution



 Workaround :

  • Disable GRT and run the Backup

Note:- Before applying the workaround make sure that the Backup to Disk folder is not complaining about low disk space. This Issue is specific to when there is a lot of disk space available, but still randomly a Backup job can get stuck at loading media and has to be eventually cancelled.
