In addition to creating a backup database, you should periodically take dumps of the RACF® database. The dumps could be part of the procedure to create backup copies of other important system data. To make the copies usable, you should create them with a dump/restore program while the system is inactive. If an inactive system cannot be guaranteed, you should use IRRUT200, which issues the proper serialization for the RACF database. IRRUT200 can produce only disk output; for tape, you should provide an additional copy step. Of course, the RACF databases and all copies should be RACF-protected at all times.
