Hello Everyone,
We have 4 media server running RHEL 6.1, netbackup 7.6.0.1.
Storage target is DataDomain
Master server is Solaris 10, running netbackup 7.6.0.1
all 4 media servers have bonding configured. ex.as below:
below is bonding status of one of the media server :
Link speed is 10gbps for each nic

================================================================
I am seeing my huge file servers full backup is only failing with code 13/24 and its failing randomly after 50gb, or lets say 1 tb.
Even Oracle jobs are failing intermitently with Network error.
No issues with incremental backup.
=================================================
Testing of one full backup with one of the media server which does not have bonding was successfull without any retry.
logged a case with Symantec still no luck yet.
so does it look bonding may cuase network drop.
Kindly adivse, also let me know if any recommneded bonding/ mostly used bonding mode.
What is the best bonding mode.
