Abstract

Systems and methods are disclosed for cross-system storage management for transferring data across autonomous information management systems. Data may be transferred from one information management system to another information management system without interfering with or overriding each system'"'"'s autonomy. For example, a secondary copy of production data (e.g., backed up data) is transferred from a first information management system that originated the data to a component of another “foreign” information management system. A first storage manager that manages the first information management system also manages the cross-system data transfer operation to a “foreign” client computing device, which remains under autonomous management as a component of the foreign information management system.

Claims

1. A method comprising:

by a first computing device, using shared binaries to instantiate (i) a first executable version of an information management software, and (ii) a second executable version of the information management software;

by the first computing device, executing (a) the first executable version of the information management software for operating in a first information management system, and (b) the second executable version of the information management software for operating in a second information management system,

wherein the second executable version of the information management software is for creating secondary copies of data generated by the first computing device according to at least one storage policy configured in the second information management system, and

wherein no storage policies for the data generated by the first computing device are configured in the first information management system;

by a first storage manager in the first information management system, causing a secondary copy of data generated in the first information management system to be transferred to the first computing device executing the first executable version of the information management software, thereby restoring the secondary copy of data to the first computing device, and

wherein the first storage manager receives information about the first computing device from a second storage manager in the second information management system;

after the secondary copy of data has been transferred, the first computing device stops executing the first executable version of the information management software; and

wherein the second storage manager is hosted by a second computing device and wherein the first storage manager is hosted by a third computing device.

2. The method of claim 1 wherein the restoring is from a media agent in the first information management system, and wherein the media agent is hosted by a fourth computing device.

3. The method of claim 1, wherein the information management software is a data agent.

4. The method of claim 1, wherein at least one of the first storage manager and the second storage manager causes the first computing device to stop executing the first executable version of the information management software.

5. The method of claim 1 further comprising:

after the secondary copy of data has been transferred to the first computing device, communicatively decoupling the first computing device from the first information management system.

6. The method of claim 5, wherein the communicatively decoupling of the first computing device from the first information management system is caused by at least one of:

the first storage manager, and the second storage manager.

7. The method of claim 1, wherein when using the second executable version of the information management software, the first computing device operates as a client of the second information management system.

8. The method of claim 1, wherein when using the first executable version of the information management software, the first computing device operates as a recipient of data transferred from the first information management system and not as a client of the first information management system.

9. The method of claim 1, wherein when using the first executable version of the information management software, the first computing device is limited to receiving data from the first information management system, but the data generated by the first computing device is not accessible to the first information management system.

10. The method of claim 1, wherein the information about the first computing device received from the second storage manager is in response to the first storage manager requesting to restore the secondary copy of data from the first information management system to the first computing device.

11. The method of claim 1, wherein the information about the first computing device received from the second storage manager comprises registry-only information that is sufficient for the transfer of the secondary copy of data but insufficient for the first computing device to operate as a client of the first information management system.

12. The method of claim 1, wherein after the secondary copy of data has been transferred, the restored secondary copy is made part of the second information management system.

13. A non-transitory computer-readable medium storing instructions that, when executed by a first computing device comprising one or more processors, cause the first computing device to perform operations comprising:

use shared binaries to instantiate (i) a first executable version of an information management software, and (ii) a second executable version of the information management software;

execute (a) the first executable version of the information management software for operating in a first information management system, and (b) the second executable version of the information management software for operating in a second information management system,

wherein the second executable version of the information management software is for creating secondary copies of data generated by the first computing device based on at least one storage policy configured in the second information management system, and

wherein no storage policies for the data generated by the first computing device are configured in the first information management system;

while executing the first executable version of the information management software, receive from the first information management system a secondary copy of data created in the first information management system, thereby restoring the secondary copy of data to the first computing device, and

wherein a first storage manager in the first information management system receives information about the first computing device from a second storage manager in the second information management system;

communicatively decouple from the first information management system after the secondary copy of data has been received; and

wherein the second storage manager is hosted by a second computing device and wherein the first storage manager is hosted by a third computing device.

14. The non-transitory computer-readable medium of claim 13, wherein the operations further comprise:

stop executing the first executable version of the information management software after the secondary copy of data has been received.

15. The non-transitory computer-readable medium of claim 13, wherein when using the second executable version of the information management software, the first computing device operates as a client of the second information management system, and

wherein when using the first executable version of the information management software, the first computing device operates as a recipient of data transferred from the first information management system and not as a client of the first information management system.

16. The non-transitory computer-readable medium of claim 13, wherein when using the first executable version of the information management software, the first computing device is limited to receiving data from the first information management system, but the data generated by the first computing device is not accessible to the first information management system.

17. A system comprising a first computing device comprising one or more processors and computer-readable memory, wherein the first computing device is configured to:

use shared binaries to instantiate (i) a first executable version of an information management software, and (ii) a second executable version of the information management software;

execute (a) the first executable version of the information management software for operating in a first information management system, and (b) the second executable version of the information management software for operating in a second information management system,

wherein the second executable version of the information management software is for creating secondary copies of data generated by the first computing device based on at least one storage policy configured in the second information management system, and

wherein the data generated by the first computing device is not accessible to the first information management system;

while executing the first executable version of the information management software, restore a secondary copy of data received from the first information management system to the first computing device,

wherein a first storage manager in the first information management system receives information about the first computing device from a second storage manager in the second information management system;

communicatively decouple from the first information management system after the secondary copy of data has been received; and

wherein the second storage manager is hosted by a second computing device and wherein the first storage manager is hosted by a third computing device.

18. The system of claim 17, wherein when the first computing device uses the first executable version of the information management software, the first computing device is limited to receiving data from the first information management system, but the data generated by the first computing device is not accessible to the first information management system;

and

wherein the restored secondary copy of data is accessible to the second information management system.

19. The system of claim 17, wherein no storage policies for the data generated by the first computing device are configured in the first information management system.

20. The system of claim 17, wherein the information about the first computing device received from the second storage manager comprises registry-only information that is sufficient for transferring the secondary copy of data to the first computing device but insufficient for the first computing device to operate as a client of the first information management system.
