FDRCRYFM DUMP Statement
DUMP statement
The DUMP statement causes a formatted backup copy of the Encryption Keyfile to be created. This backup is not in FDR format, and can only be restored by the RESTORE statement of FDRCRYFM. This backup is not encrypted; however, data in the Encryption Keyfile is not stored in the clear so encryption keys cannot be extracted by browsing the backup. The step JCL must include a TAPE1 DD statement to specify the backup data set
The DUMP and RESTORE statements of FDRCRYFM can be used to move the Encryption Keyfile to a different device type (such as 3380 to 3390) or to change its size or blocking factor. FDRCOPY or FDRDSF DUMP/RESTORE can also be used to move the Encryption Keyfile, but does not expand or reblock the file.
