The online backup of DUAS instances is generally done with the command uxbck.
This way the restoration of a node is quickly done by reinstalling the node and restoring the files of the online backup. However, the node files directory, that contains files like U_ANTE_UPROC, U_POST_UPROC or unienv_specific.ksh/bat, are not automatically backed up.
Also the Dollar Universe Maintenance Session, based on uxbck, does not separately store these node files.
The node files are stored here:
The node files should be backed up separately. This can be achieved by one of the following options:
1. Modifying the Maintenance Session
2. Using an external backup of the Dollar Universe directories
3. Backing up the instance regularly offline using unibackup (with the "full" option)
