Information management by a media agent in the absence of communications with a storage manager
View Patent ↗A media agent is configured to perform substantially autonomously to initiate, continue, and manage information management operations such as a backup job of a certain client's primary data, manage the operations, and generate and store resultant system-level metadata from the operations, etc. The media agent is configured to do this even when out of communication with the storage manager that manages the information management system. When communications are restored, the media agent reports the relevant metadata to the storage manager such that the storage manager may seamlessly integrate the information into its management information infrastructure.

8. The system of claim 1 , wherein the management parameters received from the storage manager comprise at least one storage policy associated with at least some of the data accessible to the client computing device.
9. The system of claim 1 , wherein the management parameters received from the storage manager comprise at least one storage policy, and wherein the information management job is based on the storage policy.
10. The system of claim 1 , wherein the metadata transmitted to the storage manager comprises an association between the information management job and the secondary storage computing device.
11. The system of claim 1 , wherein the metadata transmitted to the storage manager comprises an association between the information management job and a media agent that comprises the executable logic that executes on the secondary storage computing device.
12. An information management system comprising:
a first computing device for hosting a storage manager for managing the information management system;
a secondary storage device;
a secondary storage computing device in communication with (i) the secondary storage device and (ii) a client computing device, the secondary storage computing device comprising:
executable logic, and
management parameters received from the storage manager in anticipation of the secondary storage computing device being out of communication with the storage manager;
wherein, based at least in part on the executable logic and one or more of the management parameters,
the secondary storage computing device is configured to initiate and manage without being directed by the storage manager or by any other storage manager,
while one or both of the secondary storage computing device and the client computing device are out of communication with the storage manager,
an information management job to make one or more secondary copies, to be stored to the secondary storage device, of at least a portion of primary data that is accessible to the client computing device;
wherein, based at least in part on the executable logic, the secondary storage computing device is further configured to transmit to the storage manager after communications thereto resume metadata that is based on the information management job.
13. The information management system of claim 12 , wherein the storage manager is configured to integrate the metadata received from the secondary storage computing device into a management database that comprises information about secondary copies in the information management system.
14. The information management system of claim 12 , wherein the information management job is a secondary copy operation for the portion of primary data generated by the client computing device
if the information management job is successful, the secondary storage computing device, based on the executable logic, is further configured to (a) store the one or more secondary copies to the secondary storage device, (b) for each of the one or more secondary copies, keep track of a respective storage location therefor in the secondary storage device in an index in the secondary storage computing device, and (c) generate the metadata to be transmitted to the storage manager indicating that the one or more secondary copies were made; and
