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;
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;
a third storage manager comprising computer hardware, the third storage manager automatically directs transfer of the first media agent to the second storage operation cell based on a prediction of future utilization of a first operational characteristic;
wherein the second storage operation cell reconstitutes the first media agent and a copy of the first index in association with the second storage operation cell;
wherein when the second storage operation cell determines that the copy of the first index is incomplete, the second storage operation cell performs a restore operation from at least a portion of the secondary data stored in the one or more secondary storage devices to restore the copy of the first index stored in association with the second storage operation cell; and
wherein after restoration of the copy of the first index stored in association with the second storage operation cell, the second storage operation cell directs the first media agent to copy a second portion of the primary data to the one or more secondary storage devices and update the copy of the first index.

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.
