Abstract

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.

Claims

1. A system for making secondary copies of data while a storage manager is out of communication with other components in the system, the system comprising:

a first computing device for hosting a storage manager;

a storage device for storing secondary copies of data;

a second computing device in communication with (i) the storage device and (ii) a client computing device, the second computing device comprising;

executable logic, and management parameters received from the storage manager in anticipation of the second computing device being out of communication with the storage manager;

wherein the second computing device is configured, based at least in part on the executable logic and one or more of the management parameters, to;

autonomously initiate and manage one or more secondary copy operations for a portion of primary data accessible to the client computing device,

while the second computing device is out of communication with the storage manager and without being directed by the storage manager or by any other storage manager,

while the client computing device is also out of communication with the storage manager, and

generate

metadata that is based on results from the one or more secondary copy operations to be transmitted to the storage manager after communications therewith resume; and

for a first secondary copy operation among the one or more secondary copy operations that is successful, the second computing device is further configured to;

(a) generate at least one secondary copy of the portion of the primary data, (b) store the at least one secondary copy to the storage device, and (c) based on results of the first secondary copy operation, generate first metadata indicating that the at least one secondary copy was generated.

2. The system of claim 1, further comprising:

for a second secondary copy operation among the one or more secondary copy operations that fails in whole or in part, the second computing device is further configured to generate second metadata to be transmitted to the storage manager indicating that the second secondary copy operation failed in whole or in part, respectively.

3. The system of claim 1, wherein the metadata that is based on the results from the one or more secondary copy operations is configured for integration into a management database maintained by the storage manager.

4. The system of claim 1, wherein the metadata that is based on the results from the one or more secondary copy operations identifies the client computing device and the portion of the primary data processed by the one or more secondary copy operations.

5. The system of claim 1, wherein to initiate and manage the one or more secondary copy operations while out of communication with the storage manager, the second computing device is further configured to:

instruct the client computing device to transmit to the second computing device the portion of the primary data processed for backup,

generate at least one secondary copy based on the portion of primary data processed for backup,

store the at least one secondary copy to the storage device, and generate metadata about the at least one secondary copy.

6. The system of claim 1, wherein to initiate and manage the one or more secondary copy operations while out of communication with the storage manager, the second computing device is further configured to:

instruct the client computing device to transmit to the second computing device the portion of primary data processed for backup,

generate at least one secondary copy based on the portion of the primary data processed for backup,

store the at least one secondary copy to the storage device, and

generate and store metadata that identifies at least the client computing device and the portion of the primary data processed by the one or more secondary copy operations.

7. 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 primary data accessible to the client computing device.

8. The system of claim 1, wherein

based at least in part on the executable logic, the second computing device is further configured to:

transmit to the storage manager after communications therewith resume, the metadata that is based on the results from the one or more secondary copy operations, including the results of the first secondary copy operation.

9. The system of claim 1, wherein the metadata to be transmitted to the storage manager comprises a respective association between the one or more secondary copy operations and a media agent that comprises the executable logic that executes on the second computing device.

10. The system of claim 1, wherein a media agent that comprises the executable logic that executes on the second computing device is associated with each secondary copy generated by the one or more secondary copy operations performed while the second computing device is out of communication with the storage manager.

11. The system of claim 1, wherein a media agent that comprises the executable logic that executes on the second computing device is associated with each secondary copy generated by the one or more secondary copy operations performed while the second computing device is out of communication with the storage manager, and further wherein associations between the media agent and each secondary copy are included in the metadata to be transmitted to the storage manager after communications therewith resume.

12. A method comprising:

generating primary data by a client computing device, wherein the client computing device is a component of an information management system managed by a storage manager which is hosted by a first computing device; and

initiating and managing, by a media agent executing on a second computing device,

while out of communication with the storage manager, and

without being directed by the storage manager or by any other storage manager,

one or more secondary copy operations,

wherein the initiating and managing are based on an information management policy previously received by the media agent from the storage manager in anticipation of the second computing device being out of communication with the storage manager;

wherein the initiating and managing, by the media agent, comprises;

instructing the client computing device to transmit to the media agent a portion of primary data accessible to the client computing device, wherein the portion of primary data is processed for backup before being transmitted to the media agent,

generating at least one secondary copy based on the portion of primary data processed for backup,

storing the at least one secondary copy to one or more storage devices in communication with the second computing device, and

generating metadata comprising information about the one or more secondary copy operations; and

by the storage manager, integrating the metadata as received from the media agent into a management database that comprises information about secondary copies in the information management system.

13. The method of claim 12, wherein the initiating and managing occurs while the client computing device is also out of communication with the storage manager.

14. The method of claim 12, wherein the information management policy is included in one or more management parameters requested by the media agent from the storage manager.

15. The method of claim 12, further comprising:

if a first secondary copy operation among the one or more secondary copy operations fails in whole or in part, the metadata generated by the media agent indicates that the first secondary copy operation failed.
