Problems with deduplication with 2010 R3

[Nazkali]

Hi, 

I have been struggling with few problems concerning to Backup Exec 2010 R3 and deduplication. Jobs that I have uses client-side deduplication, and they now stuck on queued-state as soon as they get ~50GB. When I cancel them, job logs says:

Media mount failed.

User canceled a Physical Volume Library operation.

There is also lots of scratch media in the dedup folder. Also I can't restore now cause some restore jobs stays on queued-state from the start.

Any help? 

My target device is NetApp FAS2240-2

...how does this TN even address the OP's issue?

[Nazkali]

Still jobs stay on queue, they won't even backup that ~50GB...

How is the NetApp connected to the media server?  Uing iSCSI?

[Nazkali]

No, Fibre Channel.

...what size are the B2D files and what are your OPP/Append settings? Has this ever worked or is it a new issue?

[Nazkali]

Default size for deduplication, 50GB I think. Media management is on Overwrite. Has worked before. First time I got these errors was when I installed latest hot fixes.

I can't even restore data, because jobs stay in queued. Just found out that restarting services helped for a while with restore.

...uninstall the fixes you installed and see if this helps. If it does, then start installing them one-by-one to check which 1 caused the issue.

Thanks!

Craig,

as you're referring to my problem:

I've got the same impression, that one of the last patches/fiexes caused the actual problems.

Before that the backups were running fine with full speed for several weeks/months.

I tried to uninstall, but there is few updates that can't be uninstalled... I think one of them is causing problems? 

Should I try repairing installation? 

Few weeks back I even formatted dedup folder and did it from scratch, but the problem started after few Full backups.

[CraigV]

...give it a bash. Also consider repairing the BEDB using BEutility.exe.

Thanks!

Correct, based on AIT-2 tapes IIRC.  Wierd if you ask me.

Changed jobs to media server dedup, it helped.
