1. Next I try to create DB2 backup job manually and try to run. But it failed. You can find errors in log file.

Below is extracted from log

Next I try to backup DB2 database in DB2 client. That's OK.

Using the following command

Db2 backup db CUSTDB load c:\db2_legato\libnsrdb2.dll @options c:\db2_legato\nmddb2.new

It can be backed up to the networker server's staging disk volume.
