How to Improve performances in Netbackup Windows FlashBackup policy

[mauog]

Hi all,
I'm backupping a whole disk of a windows server using a flashbackup policy as \\.E: writing to a PDDO storage unit.
At the moment the backup speed is nearly 10000 Kbyte/sec and data are moved over a 1Gbit LAN network.
Because it isn't possible split the backup in different streams I would like to know if  I can tune some parameter of my involved servers to try to improove this speed.
Could anybody give me some hints?

Thank You

Regards

Mauro

First you need to check that the network can carry the amount of data wanted. I usally use Netcordia's ttcp test utility. It's very good to show network with a cork in them.

The default values are a little weak and won't show the true bandwidth  - This is the command I use:

Reciver side:
java ttcp -r -l 65536 -n 16384

Sender side:
java ttcp  -l 65536 -n 16384 -t {hostname}

Output looks like this:

Transmit: 1073741824 bytes in 9299 milli-seconds = 115468.52 KB/sec (923748.2 Kbps).

In the example we are pretty close to the full gigabit capacity.
