backup exec 2012 - file server backup fails
I have the following setup in my organisation:
Backup Exec 2012 installed on Win 2008 R2 virtual server
Servers being backed up successfully:
Physical Win 2008 R2 Domain Controller (System State)
Virtual Exchange 2010 server (win 2008 R2)
We use XenCenter for Virtualization.
The (Virtual) Win 2008 R2 file server backup fails within 2 minutes of the start with "the job failed with the following error: a communications failure has occurred"
The target for all of these backups is a physical server running freeNAS with 1.5Tb available. As I say the PDC and exchange backups to the freeNAS server are successful.
Please advise how to proceed. This has been going on for sometime (months) and we've failed to find a solution. We've been using a non BE method for backup as a fail-safe but this is no longer acceptable.
