POINT-IN-TIME-COPY CREATION FOR DIRECT CLOUD BACKUP
First Claim
1. A method for backing up data, the method comprising:
- sending, from a host system to a storage system, a first request to make a logical point-in-time copy of production data on the storage system;
executing, by the storage system, the first request by creating the logical point-in-time copy on the storage system;
assigning an identifier to the logical point-in-time copy;
sending, from the host system to the storage system, a second request to directly copy a specified portion of data in the logical point-in-time copy to cloud storage, the second request identifying the logical point-in-time copy using the identifier; and
executing, by the storage system, the second request by directly copying the specified portion from the logical point-in-time copy to the cloud storage.

Abstract
A method for backing up data is disclosed. In one embodiment, such a method includes sending, from a host system to a storage system, a first request to make a logical point-in-time copy of production data on the storage system. The storage system executes the first request by creating the logical point-in-time copy thereon. An identifier is assigned to the logical point-in-time copy. The method further sends, from the host system to the storage system, a second request to directly copy a specified portion of data in the logical point-in-time copy to cloud storage. The second request identifies the logical point-in-time copy using the identifier. The storage system executes the second request by directly copying the specified portion from the logical point-in-time copy to the cloud storage. A corresponding system and computer program product are also disclosed.

8. A computer program product for backing up data, the computer program product comprising a computer-readable medium having computer-usable program code embodied therein, the computer-usable program code comprising:
-
computer-usable program code to send, from a host system to a storage system, a first request to make a logical point-in-time copy of production data on the storage system; computer-usable program code to enable the storage system execute the first request by creating the logical point-in-time copy on the storage system; computer-usable program code to assign an identifier to the logical point-in-time copy; computer-usable program code to send, from the host system to the storage system, a second request to directly copy a specified portion of data in the logical point-in-time copy to cloud storage, the second request identifying the logical point-in-time copy using the identifier; and computer-usable program code to enable the storage system to execute the second request by directly copying the specified portion from the logical point-in-time copy to the cloud storage. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for backing up data, the system comprising:
-
at least one processor; at least one memory device operably coupled to the at least one processor and storing instructions for execution on the at least one processor, the instructions causing the at least one processor to; send, from a host system to a storage system, a first request to make a logical point-in-time copy of production data on the storage system; enable the storage system to execute the first request by creating the logical point-in-time copy on the storage system; assign an identifier to the logical point-in-time copy; send, from the host system to the storage system, a second request to directly copy a specified portion of data in the logical point-in-time copy to cloud storage, the second request identifying the logical point-in-time copy using the identifier; and enable the storage system to execute the second request by directly copying the specified portion from the logical point-in-time copy to the cloud storage. - View Dependent Claims (16, 17, 18, 19, 20)
