Another failed backup error that makes no sense

I am getting the following error for a number of backups and it makes no sense as we do not make use of Remote Agents. We use NDMP backups yet the following error message crops up:

 
Final error: 0xe000fefd - The Backup Exec server has lost the network connection to the Agent for Windows.
 
 
When expanding the NDMP log, I see the following:
 
NDMP Log Message: DUMP: creating "/vol/DCBL_SAHOST_VMOS_04/../snapshot_for_backup.79" snapshot.
NDMP Log Message: DUMP: Using Partial Volume Dump of selected subtrees

Any ideas on how to avoid this?

    Do you have any kind of firewall or other network device that might have a short keep alive setting configured (in between the media server and the NDMP Storage device)?

     

    The keep alive timeouts can kill the NDMP control connection because the backup ran for a long time and this could then be the cause of this type of error.

     

    Oh and because the Backup Exec Remote Agent also uses a subset of the NDMP protocol you will from time to time see error messages that apear to relate to remote agents when you are actually doing an NDMP option backup.
