BackupExec - job complete with exceptions

[Verneti_Berny]

Hi, I have a problem with backupexec 13.0.

We have four plants with the same server scenario:

Windows server 2008

BackupExec 13.0 Rev. 4164 64bits

Tape Unit Dell PV100T

In one of these plants I have a problem, my backup job finished with exceptions, as follow:

- Backup- FRNFPS1

I already checked configurations of all of my plants and they are the same.

Can anybody help me?
