Why aren't you doing it the other way around? Schedule a mksysb in the
crontab of the servers to be backed up. Mount the filesystem of the
NIM-server via NFS. This has proven to be the best, including an
incremental backup of the mksysbs after all backups should have been done.
If discspace is a concern, you can even delete the mksysb after a successful
generation and backup.
No need to tweak around with the NIM-definitions in this case as the name of
the mksysb stay the same.
