Hi Steve,

Unfortunately no ideas on my part - we have been seeing quite a few slow
performance issues on Novell as well. When we back the data up to the backup
server we get dog slow speeds (50KB - 100KB /s). Everything is checked out
fine (all tsa's and network etc).

When we stream the data to a storage node - we get "normal" throughputs (6MB
/s) ...

Only variable here is the backup server itself. All has been triple checked
a few times and I even went as far as to go "bakc" (shiver) to auto
detection on network card speeds etc (obviously this didnt solve our
problem).

Im starting to lose my faith in Novell here ... heh heh

Hello All...

We are running NDPS (NDPS Manager 3.01 & NDPS Print Subsystem 3.0) on a
Novell 6.0 SP3 box and are seeing very slow backups (1 mb/sec) while
backing any volume on that server.  The NDPS volume is part of a Virtual
Server thats data resides in a Novell Cluster.

If NDPS gets transferred to one of the other clustered servers, the
problem follows, and the original server starts backing up at proper
speeds (4-7 mb/sec) again.  If we backup everything and exclude NDPS
from the backup savesets, all works OK, but as soon as the backup
touches the NDPS volume, it is back to 1mb/sec backup speeds.

We are running Legato Networker 6.1.3 Server on a unix server and
running the legato novell 4.21g client on the Novell box.

Legato as usual has no clue on this and states that none of their
customers have reported anything along these lines.  Found this hard to
believe.

Any idea's???

Thank you,
Steve
