Efficient Flashcopy backup and mount, clone, or restore collision avoidance using dynamic volume allocation with reuse and from a shared resource pool
First Claim
1. A method for efficient point-in-time copy backup and a mount, clone, instant restore, and/or file level restore task collision avoidance using dynamic volume allocation with reuse and from a shared resource pool by a processor device in a computing environment, the method comprising:
- when executing a new point-in-time copy backup, performing at least one attempt to reuse an existing point-in-time copy target volume in a point-in-time copy chain of target volumes, wherein the existing point-in-time copy target volume is not currently being used for at least one of the mount task, the clone task, and the restore task at the same time for the new point-in-time copy backup;
wherein, if the at least one attempt to reuse the existing point-in-time copy target volume fails;
dynamically allocating a new point-in-time copy target volume for the new point-in-time copy backup from a global pool of point-in-time copy backup target volumes shared by a plurality of device classes;
wherein the new point-in-time copy target volume is allocated to avoid a collision between the new point-in-time copy backup and the existing point-in-time copy target volume, the existing point-in-time copy target volume containing an older point-in-time copy backup being ingested into a repository.

Abstract
For efficient Flashcopy backup and a mount, clone, instant restore, and/or file level restore task collision avoidance using dynamic volume allocation with reuse and from a shared resource pool, performing at least one attempt to reuse an existing FlashCopy target volume in a Flashcopy chain of target volumes that is not currently being used for at least one of the mount task, the clone task, instant restore task, and/or file level 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 from a global pool of Flashcopy backup target volumes shared by a plurality of device classes.

8. A system for efficient point-in-time copy backup and mount, clone, instant restore, and/or file level restore collision avoidance using dynamic volume allocation from a shared resource pool in a computing environment, the system comprising:
at least one processor device operable in the computing storage environment, wherein the at least one processor device; when executing a new point-in-time copy backup, performs at least one attempt to reuse an existing point-in-time copy target volume in a point-in-time copy chain of target volumes, wherein the existing point-in-time copy target volume is not currently being used for at least one of the mount task, the clone task, the instant restore task, or the file level restore task at the same time for the new point-in-time copy backup;
wherein, if the at least one attempt to reuse the existing point-in-time copy target volume fails;dynamically allocates a new point-in-time copy target volume for the new point-in-time copy backup from a global pool of point-in-time copy backup target volumes shared by a plurality of device classes;
wherein the new point-in-time copy target volume is allocated to avoid a collision between the new point-in-time copy backup and the existing point-in-time copy target volume, the existing point-in-time copy target volume containing an older point-in-time copy backup being ingested into a repository.- View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product for efficient point-in-time copy backup and mount, clone, or restore collision avoidance using dynamic volume allocation from a shared resource pool in a computing environment by a processor device, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
a first executable portion that, when executing a new point-in-time copy backup, performs at least one attempt to reuse an existing point-in-time copy target volume in a point-in-time copy chain of target volumes, wherein the existing point-in-time copy target volume is not currently being used for at least one of the mount task, the clone task, and the restore task at the same time for the new point-in-time copy backup;
wherein, if the at least one attempt to reuse the existing point-in-time copy target volume fails;dynamically allocates a new point-in-time copy target volume for the new point-in-time copy backup from a global pool of point-in-time copy backup target volumes shared by a plurality of device classes;
wherein the new point-in-time copy target volume is allocated to avoid a collision between the new point-in-time copy backup and the existing point-in-time copy target volume, the existing point-in-time copy target volume containing an older point-in-time copy backup being ingested into a repository.- View Dependent Claims (16, 17, 18, 19, 20)
