Hi all, i'm using backup exec 2012, and i have this triouble for one job (the taget is a tape library):

Hi there,

Check the forum query below, specifically the solution offered. This was for a previous version of BE, but it might still be related.

In the event viewer of bexec server i have this notice:

The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume BackupNAS.

But the job that fails is pointed to tape library and the dedup job works without problems.

Have i to run the chkdisk on the iscsi partition?

Run that and see what it gives you. You might also want to get hold of b2dtest.exe from Symantec's site and run it against the B2D to make sure it is supported, or if there are any additional issues.

The dedup folder emulates a tape library, so the error messages might be a bit confusing.  You should run chkdsk on your iSCSI device.
