Slow backup performance
Hi
We have extremely slow performance in our new netbackup environment. It cannot do more than 8mb/sec. We don't have many clients running backups on this except few NDMP shares and nbu servers...

You need to check this value - it shoud be 262144. If the backup really use 1K block size it will be very very slow. Check SIZE_DATA_BUFFERS_NDMP on the media server that control the NDMP backup.
