What major changes I'll have to do incase the OS is Linux.

The data transfer (throughput) rate is 14mb/sec.
cd /usr/openv/netbackup/logs/bptm
grep -i "KBytes/sec" log.*
transfer rate is 18632.911 Kbytes/sec

Let me explain u abt my setup:
NBU 5.1 MP3
HP StorageWorks MSL 6000
HP Ultrium LTO 3 cartridges

Changes made, but still struggling to get the speed.
/usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS =3D 256kb
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS =3D 16

After creating these files, backup was fired at the speed of 18mb/sec.

Do i have to change any directives in
/etc/sysctl.conf

Cheers,
Nouresh
