Hello Aga_K2.
To save frames' coordinates, please download the project from the controller of your LBR iiwa first.
Once you download a project, you might see the project's frames' coordinates in the Sunrise Workbench.
Manually you can log these values for a backup.
About the backup manager program, I havent heard about it before.
Please ask your Kuka customer service wheather it is a software option.
If it is not a software option, maybe you can find a java application in samples like "transport" or GMSReferencing or BrakeTest.
Note that even though your frames coordinates are backuped, if your robots and surroundings physically move you need re-touchup.
Hope this helps.
