Netbackup 7.5 with Exchange DAG 2010

[karmel]

Hello Experts,

i am facing an issue with exchange backup,

I am running Exchange 2010, DAG on windows 2008 R2

Master/Media are running on the same box, solaris 10 with Netbackuo v 7.5, backup stores data to a Basic Disk i have created on the Master/Media server, exchange database size is small (3GB).

Checkpoint FW is in between the Master/Media and the exchange.

------------------------------------------------

the backup starts just fine, couple of snapshot jobs succeeded as per below logs

status 24 is mainly on network ... ask ur nework team to monitor simultaneously.

Also run SAS and share it with symantec team they'll get back to you with report on network loss if found in SAS output
