Recovering from a copy pool incremental version

There are no additional keywords to recover from a DASD copy pool incremental version. When a volume from an incremental version or a copy pool incremental version is recovered, only the tracks that have changed since the time the backup version was created are copied back to the source volumes. After the background copy for the recovery is complete, the persistent incremental relationships are withdrawn. The copy pool still remains incremental, and the incremental relationships are re-established once the new incremental version is created. When the new backup copy is created for the incremental version, the FlashCopy® incremental relationship is re-established by creating a full copy of each volume.

The following restrictions apply to recovering from an incremental version:
  • To use reverse restore, the FlashCopy incremental relationship must be the only relationship and the background copy must have completed.
  • To use fast reverse restore, the FlashCopy incremental relationship must be the only relationship. The background copy may be in process.

When a non-incremental copy pool version is recovered while an incremental version exists, the FlashCopy incremental volume relationships are withdrawn if the background copies of the incremental volume relationships have completed. The incremental version remains recoverable. If the FlashCopy incremental background copies are still active at the time the non-incremental version recovery is requested, the request fails. If the FlashCopy incremental relationships for the incremental version are persistent, individual volume recovery using the TOVOLUME keyword from a non-incremental copy pool version fails regardless of completion of the background copy.
