generating temporary files for the plurality of users;

storing the second set of source-format data sets in the temporary files;

converting the second set of source-format data sets to target-format data sets using a backup storage mapping wherein the backup agent comprises a backup storage mapping, a dispatcher, and a data mining tool; and

initiating a transfer of the target-format data sets to the cloud-based service.

3. The method of claim 1 , wherein the second set of source-format data sets are initially stored in the backup storage system.

4. The method of claim 1 , wherein the hierarchical structure specifies at least one source-format data set associated with a user of the plurality of users.

5. The method of claim 1 , wherein a source format data set of the second set of source-format data sets is a mailbox in a source format, and wherein a target-format data set is the mailbox in a target format.

6. The method of claim 1 , wherein prior to generating the cloud-based service user accounts, the plurality of users are grouped into user batches.

7. The method of claim 6 , wherein initiating a migration of the second set of source-format data sets is performed on a per-user batch basis.

8. A system, comprising:

a processor; and

memory comprising instructions which, when executed by the processor, perform a method, the method comprising:

obtaining, by a backup agent, a migration request, wherein the migration request specifies a plurality of users; and

in response to the migration request:

identifying a set of source-format data sets in a backup storage system;

mounting the set of source-format data sets from the backup storage system;

performing data mining on the set of source-format data sets in response to the mounting to obtain a hierarchical structure;

generating a cloud-based service user account for each user of the plurality of users, wherein the cloud-based service user accounts are associated with a cloud-based service;

obtaining a second set of source-format data sets associated with each user of the plurality of users using the hierarchical structure; and

initiating a migration of the second set of source-format data sets to the cloud-based service.

9. The system of claim 8 , wherein initiating the migration of the second set of source-format data sets comprises:

generating temporary files for the plurality of users;

storing the second set of source-format data sets in the temporary files;

converting the second set of source-format data sets to target-format data sets using a backup storage mapping wherein the backup agent comprises a backup storage mapping, a dispatcher, and a data mining tool; and

initiating a transfer of the target-format data sets to the cloud-based service.

10. The system of claim 8 , wherein the second set of source-format data sets are initially stored in the backup storage system.

11. The system of claim 8 , wherein the hierarchical structure specifies at least one source-format data set associated with a user of the plurality of users.

12. The system of claim 8 , wherein a source format data set of the second set of source format data sets is a mailbox in a source format, and wherein a target-format data set is the mailbox in a target format.

13. The system of claim 8 , wherein prior to generating the cloud-based service user accounts, the plurality of users are grouped into user batches.

14. The system of claim 8 , wherein initiating a migration of the second set of source-format data sets is performed on a per-user batch basis.

15. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing data, the method comprising:

obtaining, by a backup agent, a migration request, wherein the migration request specifies a plurality of users; and

in response to the migration request:

identifying a set of source-format data sets in a backup storage system;

mounting the set of source-format data sets from the backup storage system;

performing data mining on the set of source-format data sets in response to the mounting to obtain a hierarchical structure;

generating a cloud-based service user account for each user of the plurality of users, wherein the cloud-based service user accounts are associated with a cloud-based service;

obtaining a second set of source-format data sets associated with each user of the plurality of users using the hierarchical structure; and

initiating a migration of the second set of source-format data sets to the cloud-based service.

16. The non-transitory computer readable medium of claim 15 , wherein initiating the migration of the second set of source-format data sets comprises:

generating temporary files for the plurality of users;

storing the second set of source-format data sets in the temporary files;

converting the second set of source-format data sets to target-format data sets using a backup storage mapping wherein the backup agent comprises a backup storage mapping, a dispatcher, and a data mining tool; and

initiating a transfer of the target-format data sets to the cloud-based service.

17. The non-transitory computer readable medium of claim 15 , wherein the second set of source-format data sets are initially stored in the backup storage system.

18. The non-transitory computer readable medium of claim 15 , wherein the hierarchical structure specifies at least one source-format data set associated with a user of the plurality of users.

19. The non-transitory computer readable medium of claim 15 , wherein a source format data set of the second set of source-format data sets is a mailbox in a source format, and wherein a target-format data set is the mailbox in a target format.

20. The non-transitory computer readable medium of claim 15 , wherein prior to generating the cloud-based service user accounts, the plurality of users are grouped into user batches, and wherein initiating a migration of the second set of source-format data sets is performed on a per-user batch basis.
