Abstract

The invention relates to computer readable medium storing program code which when executed on a computer causes the computer to perform a method for creating a quick recovery volume of a primary data set used by a first computer in a backup storage system, which includes identifying a snapshot image of the primary data set generated by a snapshot application, creating the quick recovery volume of the primary data set from the snapshot image of the primary data set and controlling transfer of data from the first computer to an archival storage unit. In one embodiment, the invention provides a method for creating a quick recovery volume of a primary data set that includes creating a snapshot image of the primary data set and creating a quick recovery volume of the primary data set from the snapshot image of the primary data set.

Claims

1. A computer-implementable method for restoring a primary data set located on a primary storage device, comprising:

providing a snapshot manager that interfaces with a backup storage system;

wherein the snapshot manager—

enables users to browse snapshot images stored on one or more of multiple secondary storage devices;

displaying data regarding creation of at least one of a full snapshot image and an incremental snapshot image,

wherein the incremental snapshot image is generated based in part on the full snapshot image; and

receiving a request for restoration of the primary data set to the primary storage device from a combination of the snapshot image and the incremental snapshot image,

wherein while restoring the primary data set input operations an output operations for the primary storage device are substantially not suspended.

4. The computer-implementable method of claim 1, wherein the snapshot image is static point-in-time representation of the primary data set.

5. The computer-implementable method of claim 1, wherein the data set comprises at least one of a primary volume and application data.

6. The computer-implementable method of claim 1, wherein the snapshot manager indexes snapshot images, wherein the snapshot indexing enables at least one of copying, deleting, displaying, browsing, changing properties, and recovering snapshot images, wherein the indexing comprises indexing of objects native to particular applications.

7. The computer-implementable method of claim 1, wherein the snapshot manager creates incremental snapshot images using different procedures for data associated with different applications running on the primary storage device.

17. The computer-implementable method of claim 6, wherein the snapshot manager indexes snapshot data, wherein the snapshot indexing enables at least one of copying, deleting, displaying, browsing, changing properties, and recovering snapshot data.

2. A non-transitory computer-readable medium having instructions which, when executed by a backup system, cause the backup system to execute a method for restoring a primary data set located on a primary storage device, comprising:

providing a snapshot manager that interfaces with a backup storage system,

wherein the snapshot manager enables users to browse snapshot images stored on one or more of multiple secondary storage devices;

displaying data regarding creation of at least one of a full snapshot image and an incremental snapshot image,

wherein the incremental snapshot image is generated based in part on the full snapshot image; and

receiving a request for restoration of the primary data set to the primary storage device from a combination of the snapshot image and the incremental snapshot image,

wherein while restoring the primary data set input operations an output operations for the primary storage device are substantially not suspended.

8. The computer-readable medium of claim 2, wherein the snapshot image is static point-in-time representation of the primary data set.

9. The computer-readable medium of claim 2, wherein the data set comprises at least one of a primary volume and application data.

10. The computer-readable medium of claim 2, wherein the snapshot manager indexes snapshot images, wherein the snapshot indexing enables at least one of copying, deleting, displaying, browsing, changing properties, and recovering snapshot images, wherein the indexing comprises indexing of objects native to particular applications.

11. The computer-readable medium of claim 2, wherein the snapshot manager indexes snapshot data, wherein the snapshot indexing enables at least one of copying, deleting, displaying, browsing, changing properties, and recovering snapshot data.

12. The computer-readable medium of claim 2, wherein the snapshot manager creates incremental snapshot images using different procedures for data associated with different applications running on the primary storage device.

3. A backup system for restoring a primary data set located on a primary storage device, comprising:

means for providing a snapshot manager that interfaces with a backup storage system,

wherein the snapshot manager enables users to browse snapshot images stored on one or more of multiple secondary storage devices;

means for displaying data regarding creation of at least one of a full snapshot image and an incremental snapshot image,

wherein the incremental snapshot image is generated based in part on the full snapshot image; and

means for receiving a request for restoration of the primary data set to the primary storage device from a combination of the snapshot image and the incremental snapshot image,

wherein while restoring the primary data set input operations an output operations for the primary storage device are substantially not suspended.

13. The system of claim 3, wherein the snapshot image is static point-in-time representation of the primary data set.

14. The system of claim 3, wherein the data set comprises at least one of a primary volume and application data.

15. The system of claim 3, wherein the means for providing a snapshot manager indexes snapshot images, wherein the snapshot indexing enables at least one of copying, deleting, displaying, browsing, changing properties, and recovering snapshot images, wherein the indexing comprises indexing of objects native to particular applications.

16. The system of claim 3, wherein the snapshot manager creates incremental snapshot images using different procedures for data associated with different applications running on the primary storage device.
