We are running ADSM server Ver. 3 Rel. 1 Level 2.40 on an OS/390 2.7
platform. The ADSM client is Ver. 3 Rel. 1 Level 0.7 running on a Novell
Netware 4.1.1 Server. Does anyone have any ideas why it would take much
longer to run an incremental backup verses a selective backup? As an
example, I specified the following object for the backup:
vol1:users/ - subdir=yes
Here is the summary after the SELECTIVE backup:

We also back up another Novell Netware 4.1.1 server incrementally with no
problems. It's client code is at a level just prior to the other server's
( 0.6). It will typically run like the following:

(Tcp/Ip 168.169.11.20(1341)).
12/17/1999 21:00:37 ANR0403I Session 268 ended for node E011LIB (NetWare).
What could be so different about the two servers?
Any insight would be appreciated. We are only operating ADSM in a test
mode now, but if we don't get this resolved it may never make it to
production. Confidence levels aren't too high around here.
