There are over 850,000 files!
I am a little concerned Netbackup would be recreating the cache for every 10
files!

Hi,

Try making this ti the NetBackup config. for the OTM:

Initial cache size: 500 
Max. cache size: 2500 
Busy file wait: 1 
Cached files: 0 
Error Control: Abort on error 

If the above Cached files is set to say, 10, then NetBackup will try to
recreate the OTM image after every 10 files.
By setting to 0, NetBackup will take the cache size as reference instead.

Another thing you can do is to force the NIC to communicate in full duplex.
By default it is in auto mode.

Hope that helps.

ACC

Hi again,
Very sorry to bother you, but I wanted some idea on throughput on
Netbackup
on NT Server
I have an NT Server client with 50GB of Data, and the majority of the
files
are all small XML files.

Presently, it has taken 1hr 25mins to backup 17.5GB

How does Netbackup cope with small files, and is there a way to increase
speed?

Many Thanks
