Enterprise Vault 11.0.1 and Backup Exec 2014

I have a problem with a customers EV system.

After an EV-upgrade with a move of the partitions (from netapp to local storage on EV-server on 2 new partitions)

I cannot backup the partitions anymore.

The savesets are growing constantly and the mailboxes are respectively. Last PartitionSecuredNotification.xml is from 24 of november (before the upgrade)

I can backup the Databases (monitoring, directory,fingerprint,vaultstore db) but I cannot backup the physical archive data of the partitions.

Backup Exec recognizes the EV-Directory with all its components.

This is the error I get when I am trying to backup the EV Directory with Backup exec:

One thing I have noticed is, that when i drill down the backup job to:

Site>>Vaultstore Group>>Mailbox>>All Partitions>>Open Partition

I cannot chose to mark the partition for backup. It is selected but it is greyed out. 

 

I would be glad, if anyone of you could help me out.

 

Thanks
