Zusammenfassung:A new target volume for a new FlashCopy backup is dynamically allocated by performing at least one attempt to reuse an existing FlashCopy target volume containing older FlashCopy backups that have been previously ingested into a repository and are not currently being used as a source for at least one of a mount task, a clone task, and a restore task. If the at least one attempt to reuse the existing FlashCopy target volume fails, the new target volume is dynamically allocated from a global pool of FlashCopy backup target volumes.
