You've already highlighted the delays and waits, so I suspect that you already know what you need to do.
bptm on the media server is waiting a lot. The client is not able to move data quickly enough to the media servers.
There's probably not a lot we can do from the NetBackup Server side of things, to speed things up.
Your first task to identify why the client is struggling to get data up from disk and across the LAN to the media server.
.
Do you know how to use the native OS tools to check a 'client' disk sub-system for performance?

Hello,
this backup was always slow or it has been slowed down after some change?
Try to backup a subset of .nsf files by filesystem policy, if it is the same, or just try to copy them from the Lotus client onto Media Server.
If yes then cause is somewhere else - speed 5kB/s is not very high, considering that it is only 542 files...

we have only one master server
and master server and lotus notes server are in the same data center

ok - are you able to logon to the client machine (i.e. the Lotus Notes server) and inspect the OS behaviour (disk and network) when a backup is running?
02-09-2016 02:40 AM
yes we are able
os behavious is ok

Some times increasing the Buffer_Size on the client can improve the speed. There might also be some transfer buffer in Lotus like on other databases.
Another that often helps is to defragment the file system/database

If client OS behaviour is OK, and you're getting 5MB/s transfer from client to media server, and media server is siiting there waiting all the time, then it all ok right? Because the client OS behaviour is ok? Right? So what are we worrying about then?
