Hi All,
I am using Netbackup appliance 5330. The backup speed suddenly decreased. We found below error in the detailed job status

This appliance is used as Target Replication from 3 other netbackup sites. This also connected to tape library as well. We logges a case with Symantec as well ( Case id - 08693217) but they didn't find anything yet. We observered last night backups started failing with 24, 87 and running very slow throughput. We ran backup for same clients from other appliance and it is running fine. So seems some issue with this appliance.
We changed TCP time stamp as well but not getting any improvement on Speed.
1.
Make a backup copy of the file to edit: # cp "/etc
/sysctl.conf /etc/
sysctl.conf.tcptimestampsoff"
2. Then in "/etc/sysctl.conf", change the line that reads:
net.ipv4.tcp_timestamps = 0
To instead read:
net.ipv4.tcp_timestamps = 1
Save the file and execute:
# sysctl -p
Once we restart netbackup service the backup running fine and after sometime it slows down. PLEASE HELP ME ASAP!!!!
