Systems and methods for migrating components in a hierarchical storage network
First Claim
1. A storage system that automatically transfers a storage resource from a first storage operation cell to a second storage operation cell, the storage system comprising:
- a first storage operation cell comprising computer hardware, the first storage operation cell monitors primary data created by one or more client computers, the primary data stored on one or more primary storage devices, the first storage operation cell comprising at least a first storage manager and at least a first media agent;
wherein the first storage operation cell directs the first media agent to copy at least a first portion of the primary data by copying the first portion of the primary data to one or more secondary storage devices to create secondary data of the primary data, and wherein the first media agent creates a first index of the secondary data; and
wherein the first storage manager monitors an operational characteristic associated with a first storage resource of the first storage operation cell,a second storage operation cell comprising computer hardware, the second storage operation cell monitors the primary data created by the one or more client computers, the second storage operation cell comprising at least a second storage manager and a second media agent;
wherein the second storage operation cell directs the second media agent to copy at least a second portion of the primary data by copying the second portion of the primary data to the one or more secondary storage devices to create the secondary data of the primary data, and wherein the second media agent creates a second index of the secondary data;
in the event the operational characteristic exceeds a threshold, initiating transfer of the first storage resource to the second storage operation cell, wherein the transfer of the first storage resource to the second storage operation cell creates a copy of management information associated with the first storage resource in the second storage operation cell;
wherein when the second storage operation cell determines that the copy of the management information is incomplete, the second storage operation cell performs a restore operation from the one or more secondary storage devices to restore the copy of the management information to the second storage operation cell.

Abstract
System and methods for selectively or automatically migrating resources between storage operation cells are provided. In accordance with one aspect of the invention, a management component within the storage operation system may monitor system operation and migrate components from storage operation cell to another to facilitate failover recovery, promote load balancing within the system and improve overall system performance as further described herein. Another aspect of the invention may involve performing certain predictive analyzes on system operation to reveal trends and tendencies within the system. Such information may be used as the basis for potentially migrating components from one storage operation cell to another to improve system performance and reduce or eliminate resource exhaustion or congestion conditions.

11. A method of automatically transferring a storage resource from a first storage operation cell to a second storage operation cell, the method comprising:
-
monitoring with a first storage operation cell comprising computer hardware, primary data created by one or more client computers, the primary data stored on one or more primary storage devices, the first storage operation cell comprising at least a first storage manager and at least a first media agent; directing the first media agent to copy at least a first portion of the primary data by copying the first portion of the primary data to one or more secondary storage devices to create secondary data of the primary data, and wherein the first media agent creates a first index of the secondary data; monitors an operational characteristic associated with a first storage resource of the first storage operation cell; monitoring with a second storage operation cell comprising computer hardware, the primary data created by the one or more client computers, the second storage operation cell comprising at least a second storage manager and a second media agent; directing the second media agent to copy at least a second portion of the primary data by copying the second portion of the primary data to the one or more secondary storage devices to create the secondary data of the primary data, and wherein the second media agent creates a second index of the secondary data; in the event the operational characteristic exceeds a threshold, initiating transfer of the first storage resource to the second storage operation cell, wherein the transfer of the first storage resource to the second storage operation cell creates a copy of management information associated with the first storage resource in the second storage operation cell; and determining that the copy of the management information in the second storage operation cell is incomplete and performing a restore operation from the one or more secondary storage devices to restore the copy of the management information to the second storage operation cell. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
