The Network Installation Manager stores it’s DB in the AIX ODM.
The backup / restore process is fairly simple. Using the following fastpath:
smitty nim_backup_db smitty nim_restore_db
The DB will be saved into the selected location.
The backup can also be performed using the CLI, backing up the following files:
/etc/niminfo /etc/objrepos/nim_attr /etc/objrepos/nim_attr.vc /etc/objrepos/nim_object /etc/objrepos/nim_object.vc
