incase no one has respoded to you yet. Are you backing up the data =
locally at the same slow speed, or are you backing up only data across =
the LAN at that slow of a speed?
At any rate. If it is local backups, make sure the applications in the =
directory you are backing up are shut down or put in hot backup mode, =
this shouldn't cause such a dramatic slow down, but it does cause some.
If it is the network, make sure that the clients and the master as well =
as the switch are hard coded with 100Mb full Duplex. If not you will =
see this type of slow down.
Good luck,
Bob

Subject: [Veritas-bu] Slow Backups
Hello All:=20
I know this is a very generic question, but has anybody run into slow =
backups (i'm sure you have)? It seems that all of a sudden we went from =
backing up 15-20GB an hour/drive to approx 2-5 GB/drive. We are not =
using SAN or SSO; simple L700's/STK9710's connected to Masters (HP-UX =
11.00/NB 3.2) via fiber to scsi bridges. We have Network and EMC teams =
looking into the issue; there is no slow down in the client's =
applications.=20
Just looking for any input on what "may" be causing this from a =
NetBAckup side.=20
Thanks.=20
