strange error on deduplicated storage folder

[reza_akhlaghy]

Hi

in a trial installation, we created a deduplicated storage (BackupExec 2010 R2) to backup an exchange server. First job will run successfully but eventually it will fail with this error:

V-79-57344-4608 - The backup-to-disk folder that was specified for this job must be on an NTFS volume. Create a new backup-to-disk folder on an NTFS volume or modify the current folder, and then submit the job again.

This error is quite misleading, and if you create a normal B2D folder it will backup without any problem.

I findout that it is a known bug, but I need to know if there is any workaround and also how can I provide more info to support to fix it quickly.

The backup-to-disk folder must exist on an NTFS partition for backup jobs in which the Granular Recovery Technology (GRT) option is selected. This option is available for Microsoft Exchange databases and storage groups, Microsoft Active Directory, and Microsoft SharePoint content database and Team database. May be same for dedup storage folder also

He alread said that the first couple of dedeup jobs work but eventually they stop working, so I doubt the problem is that the storage location is not NTFS

http://www.symantec.com/docs/TECH135975   indicated that this is a known problem and the blurb is mis-leading (as is stated by the OP)

All the OP was asking was "Is there another workaround, or is the any way to expdite the solution to the problem?"

Turn off GRT and try again.

Thanks for replies,

The reason customer chose BE 2010 is deduplication and GRT together, so turning off GRT is not an option.

Any other ideas?

Sadly, this is indeed a known issue with BE 2010 R2. We had GRT enabled backups going to the deduplication store, quite happlily for about a month and then they simply started to fail. My Error message is 0xe0001203. If I turn off GRT based backups it works fine. I am still awaiting a hotfix for this issue, so in the mean time these jobs are targeting a traditional Backup to Disc folder on a seperate drive.
