RESTORING BACKED UP DATA ACROSS AUTONOMOUS STORAGE MANAGEMENT SYSTEMS
First Claim
1. A system for restoring backed up data from one autonomous storage management system to another autonomous storage management system, the system comprising:
- a local storage management system comprising;
a secondary copy of data originated by a local client in the local storage management system,a first storage device comprising the secondary copy, anda media agent associated with the secondary copy,wherein the local storage management system is under management by a local storage manager;
a remote storage management system comprising;
a remote client, anda second storage device associated with the remote client,wherein the remote storage management system is under management by a remote storage manager;
wherein the remote client is configured as both (i) a full-fledged client of the remote storage management system, wherein the full-fledged client is an ordinary client of the remote storage management system, and (ii) a restore-only client of the local storage management system;
wherein the local storage manager comprises functionality to communicate with the remote storage manager, and further comprises functionality to manage a restore job of the secondary copy to the remote client, via the media agent; and
wherein the remote client comprises a data agent configured to receive and process the secondary copy from the media agent in the local storage management system, based on the restore-only configuration of the remote client, and to store the processed data to the second storage device.

Abstract
An exemplary system preserves the autonomy of two or more distinct storage management systems all the while enabling backed up data to be restored from a first storage management system (the “local system”) to a specially-configured client in a second storage management system (the “remote system”). For example, backed up data in the local system (e.g., a secondary copy of production data) may be transferred, in a restore operation, from secondary storage in the local storage management system, which originated the data, to a client of the remote storage management system (the “remote client”). As a specially-configured “restore-only client,” the remote client is limited to receiving backed up data from the local storage management system, via restore operation(s) managed by the local storage manager. The remote client remains a full-fledged client in its home system, the remote storage management system.

1. A system for restoring backed up data from one autonomous storage management system to another autonomous storage management system, the system comprising:
-
a local storage management system comprising; a secondary copy of data originated by a local client in the local storage management system, a first storage device comprising the secondary copy, and a media agent associated with the secondary copy, wherein the local storage management system is under management by a local storage manager; a remote storage management system comprising; a remote client, and a second storage device associated with the remote client, wherein the remote storage management system is under management by a remote storage manager; wherein the remote client is configured as both (i) a full-fledged client of the remote storage management system, wherein the full-fledged client is an ordinary client of the remote storage management system, and (ii) a restore-only client of the local storage management system; wherein the local storage manager comprises functionality to communicate with the remote storage manager, and further comprises functionality to manage a restore job of the secondary copy to the remote client, via the media agent; and wherein the remote client comprises a data agent configured to receive and process the secondary copy from the media agent in the local storage management system, based on the restore-only configuration of the remote client, and to store the processed data to the second storage device. - View Dependent Claims (2, 3, 4, 5, 6)

7. A system for restoring backed up data from one autonomous storage management system to another autonomous storage management system, the system comprising:
-
a first storage management system comprising; a secondary copy of data originated by a first client in the first storage management system, a first storage device comprising the secondary copy, and a media agent associated with the secondary copy, wherein the first storage management system is under management by a first storage manager; a second storage management system comprising; a second client, and a second storage device associated with the second client, wherein the second storage management system is under management by a second storage manager; wherein the first storage manager is configured to; administer a component to be a restore-only client, which may be a destination for restored data from the first storage management system and may not be a source of data for storage management operations in the first storage management system, administer the second client to be the restore-only client of the first storage management system; and manage a restore operation of the secondary copy of data to the second client as the destination, based on data movement performed by the media agent component of the first storage management system from the first storage device to the second client in the second storage management system, wherein the restored secondary copy is stored to the second storage device. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for restoring backed up data across autonomous storage management systems, the method comprising:
-
restoring a secondary copy of data from a first storage device component of a first storage management system to a second client, wherein the data was originated by a first client component of the first storage management system, and wherein the second client is configured as both (i) a full-fledged client of the second storage management system, and (ii) a restore-only client of the first storage management system; wherein the restoring is based at least in part on; (a) requesting, by a first storage manager that manages the first storage management system, configuration data about the second client from the second storage manager which manages the second storage management system, (b) transmitting, by the first storage manager to the second storage manager, an authentication certificate for the second client to use in the first storage management system, (c) generating, by the second storage manager, a registry key for the second client, wherein the registry key associates the second client and the first storage manager, (d) transmitting, by the second storage manager to the second client, the authentication certificate and the registry key; and wherein, based on the authentication certificate and the registry key, the second client communicates directly with the first storage manager at least once during the restore operation. - View Dependent Claims (15, 16, 17, 18, 19, 20)
