Efficient FlashCopy backup and mount, clone, or restore collision avoidance using dynamic volume allocation with reuse

摘要

For efficient Flashcopy backup and mount, clone, or restore collision avoidance with reuse using dynamic volume allocation, performing at least one attempt to reuse an existing FlashCopy target volume that is not currently being used for at least one of a mount task, a clone task, and a restore task at the same time for a FlashCopy backup. If the at least one attempt to reuse the existing FlashCopy target volume fails, dynamically allocate a new Flashcopy target volume for the Flashcopy backup.
