Restoring an archive authorized by an authenticated user

1. A method, comprising:

providing to an authenticated user a list of one or more archives available to be restored, wherein the list of one or more archives available to be restored is based in part on a credential provided by the authenticated user, wherein the credential provided by the user is linked to a subset of a plurality of snapshot archives associated with an enterprise;

receiving a selection of one of the one or more archives and an external target for the selected archive;

utilizing a cloud instantiation of a secondary storage system to reconstitute a tree data structure based on serialized data included in the selected archive, wherein the reconstituted tree data structure is comprised of at least a root node and one or more nodes storing data, wherein the serialized data is comprised of a flat set of data blocks, wherein each data block included in the flat set of data blocks corresponds to one of a plurality of nodes of the reconstituted tree data structure;

receiving a request to restore data associated with the selected archive to the external target; and

providing the requested data associated with the archive to the external target.

2. The method of claim 1 , wherein the request to restore data associated with the selected archive is for a portion of the selected archive.

3. The method of claim 1 , wherein the request to restore data associated with the selected archive is for the entire selected archive.

4. The method of claim 1 , wherein the cloud instantiation of the secondary storage system is generated in response to receiving an indication that the secondary storage system is offline.

5. The method of claim 1 , wherein the enterprise is associated with a plurality of datacenters.

6. The method of claim 5 , wherein the credential provided by the authenticated user permits the authenticated user to access archives associated with one of the plurality of datacenters.

7. The method of claim 1 , further comprising authenticating the authenticated user.

8. The method of claim 1 , wherein the external target is a primary system of a data center.

9. The method of claim 1 , wherein the external target is the secondary storage system.

10. The method of claim 1 , wherein the request to restore data associated with the selected archive specifies a format for the restored data.

11. The method of claim 1 , wherein a secondary storage cluster is virtually rebuilt in the cloud instantiation of the secondary storage system using the selected archive.

12. The method of claim 1 , further comprising reconstituting the tree data structure.

13. The method of claim 1 , wherein reconstituting the tree data structure includes deserializing a serialized data file that includes the serialized data.

14. The method of claim 1 , wherein an order of the data blocks included in the flat set of data blocks corresponds to an order of the tree data structure.

15. The method of claim 1 , wherein the selected archive corresponds to a full archive.

16. The method of claim 1 , wherein the selected archive corresponds to an incremental archive.

17. A system, comprising:

a processor; and

a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to:

provide to an authenticated user a list of one or more archives available to be restored, wherein the list of one or more archives available to be restored is based in part on a credential provided by the authenticated user, wherein the credential provided by the user is linked to a subset of a plurality of snapshot archives associated with an enterprise;

receive a selection of one of the one or more archives and an external target for the selected archive;

utilize a cloud instantiation of a secondary storage system to reconstitute a tree data structure based on serialized data included in the selected archive, wherein the reconstituted tree data structure is comprised of at least a root node and one or more nodes storing data, wherein the serialized data is comprised of a flat set of data blocks, wherein each data block included in the flat set of data blocks corresponds to one of a plurality of nodes of the reconstituted tree data structure;

receive a request to restore data associated with the selected archive to the external target; and

provide the requested data associated with the archive to the external target.

18. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

providing to an authenticated user a list of one or more archives available to be restored, wherein the list of one or more archives available to be restored is based in part on a credential provided by the authenticated user, wherein the credential provided by the user is linked to a subset of a plurality of snapshot archives associated with an enterprise;

receiving a selection of one of the one or more archives and an external target for the selected archive;

utilizing a cloud instantiation of a secondary storage system to reconstitute a tree data structure based on serialized data included in the selected archive, wherein the reconstituted tree data structure is comprised of at least a root node and one or more nodes storing data, wherein the serialized data is comprised of a flat set of data blocks, wherein each data block included in the flat set of data blocks corresponds to one of a plurality of nodes of the reconstituted tree data structure;

receiving a request to restore data associated with the selected archive to the external target; and

providing the requested data associated with the archive to the external target.

19. The computer program product of claim 18 , wherein the enterprise is associated with a plurality of datacenters.

20. The computer program product of claim 19 , wherein the credential provided by the authenticated user permits the authenticated user to access archives associated with one of the plurality of datacenters.
