Do you see any difference in the local and network backups? May be its not
getting enough feed from the clients. If only network backups are slow, check
your NIC/switch settings. Make sure they are set to 100 Mbps/Full Duplex.
NetWorker does'nt go good with Auto Sense mode.

Subject: [Networker] Backup Slows down after initial Fast start
Hi There,
Got a puzzling scenario that somebody might be able to help me with.
I have a machine that has Solaris 8 and Networker 7.1 on (havent had time to
go 711 yet).
When I do a backup on the local backup server itself the backup kicks of at
a reasonable speed for my DLT8000 device (8MB/s).
This normally lasts a couple of minutes and then starts dropping and
eventually end's up in the 100's of KB/s.
At first I thought this might be a filetype propblem (lots of small files,
but there is only the "normal" OS files and then the DB files) - but when
doing a INFORMIX raw backup I get the same symptom.
The machine itself is not running hard at all (Legato is typically using
less than 2%). Lots of disk space available, lots of everything ...
Any thoughts, perhaps suggestions where I can look next ?
All help appreciated (so late on this Friday, I just know I will be drinking
lots of coffee again tonight .... ),
Regards,
Riaan
