FCINCREMENTAL: Requesting DFSMShsm to create a copy pool version using incremental FlashCopy®

Explanation: FCINCREMENTAL is an optional keyword that can be used with EXECUTE. It can be specified with the optional subparameter ALL.

Volumes in an incremental backup version have persistent relationships.

FCINCREMENTAL(ALL) indicates that an incremental copy pool version is to be created, and all subsequent copy pool backup copies should also be incremental.

FCINCREMENTAL without the ALL subparameter indicates the version that is created is an incremental version.

Note:

1. Creating and maintaining multiple incremental backup versions causes each source volume in the copy pool to have multiple incremental targets. Each volume is allowed to have up to 12 incremental targets. That is, when you specify FCINCREMENTAL(ALL), the copy pool VERSIONS must be set to a value between 1 and 12.
2. You can specify the FCINCREMENTAL keyword (without the ALL subparameter) to designate multiple incremental copies. When a version designated as incremental is deleted, the indication of that copy as incremental is lost and the FCINCREMENTAL keyword must be re-specified on a future FRBACKUP command to create a replacement incremental backup copy.
3. If an incremental copy is desired for each copy pool backup, it is recommended that the FCINCREMENTAL(ALL) keyword (instead of multiple FCINCREMENTAL requests) be used. If all backup copies of the copy pool are deleted (both disk and tape copies), the FCINCREMENTAL(ALL) parameter must be reissued when creating the first new backup.
4. The Multiple Incremental FlashCopy target function must be enabled when attempting to create multiple incremental copy pool copies or to recover a backup version created with the Multiple Incremental FlashCopy target support. Otherwise, the FRBACKUP or FRRECOV command will fail. The Multiple Incremental FlashCopy target function can be disabled with MULTINCRFLC=NO in the DEVSUPxx member of parmlib.
