Could be any of, or a combination of, the below (not in any particular
order):
Bad drive
Slow network
Many small files being backed up
Underpowered server (client and media)
Poorly performing tape drive drivers
Poorly performing  NIC drivers
Poor NBU tuning
Full filesystem
Busy filesystem
Bandwidth throttling
Firewall
Virus scan
I could go on...
=20
Check the simple stuff like Network and what is actually being backed up
first.

=20

I  have Veritas net backup version 5.1 on windows 2000 . When I take
backup using DLT on a quantum drive the data transfer rate is very slow.

=20

The rate is almost 1 mb/sec . Any suggestions on why this is happening.
