If the diagnostic steps reveal no errors, the IDCAMS EXPORT step should be executed. If the EXPORT is successful, the backup data set should be cataloged along with the accompanying listing which gives the date and time of the catalog copy. See Figure 1 and Figure 2 for an example of the diagnostic and backup job that follows these recommendations.

We suggest that the backup job be run daily. If recovery is required, it should take only a few minutes to read the SMF records since the last backup.
