Hi Guys

I have a server 2012 netbackup client with acelerator and tracklogs configured . The backup is working but looking at increasing the speed. I have a 20Gb network beween the server and backup server ...

Looking at the backup logs I see the  entry  ) waited for full buffer 4653 times, delayed 4854649 times   

The C :\ C:\Program Files\Veritas\NetBackup\zzz- NET_BUFFER_SZ says 256 ( Media server)

is there anyway I can reset theses setting to improve the speed? what the best setting taking into consideration my current settings 

Thnaks in advance guys

waited for full buffer 4653 times, delayed 4854649 times 

means bptm process is not reciving the from the client with enough speed.. it may be because of the slow data read on the client end or the less network abliity

so first test the below things

1) test the I/O perfrormance of the client using the bpbkar null test make sure its in good speed.
