Abstract

Provided are techniques for asynchronous remote mirror cloud archival. A data mover of a remote host receives, from an asynchronous remote mirror copy system of a primary storage controller, an archive copy operation, wherein the archive copy operation identifies a list of tracks of data and a location of cloud storage in a cloud infrastructure for storing the data from the tracks. The data mover issues, to a secondary storage controller, the archive copy operation, wherein the secondary storage controller archives the data from secondary storage to the cloud storage by invoking a cloud service, wherein the secondary storage stores data of primary storage of the primary storage controller.

First claim

What is claimed is:

1. A computer program product, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform:
under control of an asynchronous remote mirror copy system of a primary storage controller,
receiving, from an application host, an asynchronous remote mirror cloud archival copy operation, wherein the asynchronous remote mirror cloud archival copy operation describes a list of tracks of data to be archived and a location in cloud storage to store the data;
issuing, to a data mover of a remote host, an archive copy operation, wherein the archive copy operation identifies the list of tracks of the data and the location of the cloud storage in a cloud infrastructure for storing the data from the tracks; and
receiving, from the data mover, a notification that the archive copy operation has completed successfully, wherein the data mover issues the archive copy operation to a secondary storage controller, and wherein the secondary storage controller archives the data from secondary storage to the cloud storage by invoking a cloud service.

2. The computer program product of claim 1 , wherein the primary storage controller receives the asynchronous remote mirror cloud archival copy operation from the application host and passes the asynchronous remote mirror cloud archival copy operation to the asynchronous remote mirror copy system.

3. The computer program product of claim 1 , wherein the secondary storage stores data of primary storage of the primary storage controller.

4. The computer program product of claim 1 , wherein the secondary storage controller generates one or more data objects from the tracks of data, and wherein the secondary storage controller stores the one or more data objects in the cloud storage.

5. The computer program product of claim 1 , wherein any of the primary storage controller and the secondary storage controller receive a request to retrieve objects from the cloud storage from any of the application host and the remote host.

6. The computer program product of claim 1 , wherein the cloud storage is coupled to the cloud service that stores data into the cloud storage and retrieves data from the cloud storage.

7. The computer program product of claim 1 , wherein the archive copy operation comprises a store record set command.

8. A computer system comprising:
one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices; and
program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to perform operations comprising:
under control of an asynchronous remote mirror copy system of a primary storage controller,
receiving, from an application host, an asynchronous remote mirror cloud archival copy operation, wherein the asynchronous remote mirror cloud archival copy operation describes a list of tracks of data to be archived and a location in cloud storage to store the data;
issuing, to a data mover of a remote host, an archive copy operation, wherein the archive copy operation identifies the list of tracks of the data and the location of the cloud storage in a cloud infrastructure for storing the data from the tracks; and
receiving, from the data mover, a notification that the archive copy operation has completed successfully, wherein the data mover issues the archive copy operation to a secondary storage controller, and wherein the secondary storage controller archives the data from secondary storage to the cloud storage by invoking a cloud service.

9. The computer system of claim 8 , wherein the primary storage controller receives the asynchronous remote mirror cloud archival copy operation from the application host and passes the asynchronous remote mirror cloud archival copy operation to the asynchronous remote mirror copy system.

10. The computer system of claim 8 , wherein the secondary storage stores data of primary storage of the primary storage controller.

11. The computer system of claim 8 , wherein the secondary storage controller generates one or more data objects from the tracks of data, and wherein the secondary storage controller stores the one or more data objects in the cloud storage.

12. The computer system of claim 8 , wherein any of the primary storage controller and the secondary storage controller receive a request to retrieve objects from the cloud storage from any of the application host and the remote host.

13. The computer system of claim 8 , wherein the cloud storage is coupled to the cloud service that stores data into the cloud storage and retrieves data from the cloud storage.

14. The computer system of claim 8 , wherein the archive copy operation comprises a store record set command.

15. A computer-implemented method, comprising:
under control of an asynchronous remote mirror copy system of a primary storage controller,
receiving, from an application host, an asynchronous remote mirror cloud archival copy operation, wherein the asynchronous remote mirror cloud archival copy operation describes a list of tracks of data to be archived and a location in cloud storage to store the data;
issuing, to a data mover of a remote host, an archive copy operation, wherein the archive copy operation identifies the list of tracks of the data and the location of the cloud storage in a cloud infrastructure for storing the data from the tracks; and
receiving, from the data mover, a notification that the archive copy operation has completed successfully, wherein the data mover issues the archive copy operation to a secondary storage controller, and wherein the secondary storage controller archives the data from secondary storage to the cloud storage by invoking a cloud service.

16. The computer-implemented method of claim 15 , wherein the primary storage controller receives the asynchronous remote mirror cloud archival copy operation from the application host and passes the asynchronous remote mirror cloud archival copy operation to the asynchronous remote mirror copy system.

17. The computer-implemented method of claim 15 , wherein the secondary storage stores data of primary storage of the primary storage controller.

18. The computer-implemented method of claim 15 , wherein the secondary storage controller generates one or more data objects from the tracks of data, and wherein the secondary storage controller stores the one or more data objects in the cloud storage.

19. The computer-implemented method of claim 15 , wherein any of the primary storage controller and the secondary storage controller receive a request to retrieve objects from the cloud storage from any of the application host and the remote host.

20. The computer-implemented method of claim 15 , wherein the cloud storage is coupled to the cloud service that stores data into the cloud storage and retrieves data from the cloud storage.
