Abstract: Rather than relying on pre-defined scheduling of secondary copy operations such as backup jobs, the illustrative opportunistic approach initiates secondary copy operations based on changing operational conditions in a storage management system. An adaptive backup readiness score is based on a number of backup-readiness operational factors. An illustrative enhanced data agent which is associated with the target database application (or other executable component) may monitor the operational factors and determine the backup readiness score based on weights assigned to the respective operational factors. The enhanced data agent may evaluate recent backup jobs to determine which of the operational factors that contributed to the backup readiness score may have been most relevant. Based on the most-relevant analysis, the enhanced data agent may adapt the weights assigned to the monitored operational factors, so that the backup readiness score may be more suitable and responsive to ongoing operational conditions in the system.

Abstract: Systems and methods are disclosed for information management, which are performed substantially autonomously by a client in the absence of a storage manager connection, and which are also streamlined to operate efficiently when the storage manager connection is restored. The illustrative client, comprising specialized logic for operating autonomously, generates secondary copies of production data that are compatible with the information management system. The client stores the secondary copies to local fast-access primary storage technology. When connected to an appropriate media agent and to the storage manager, the client moves to efficiently offload the secondary data to a proper secondary storage subsystem. The client aggregates the locally-stored secondary copies into a consolidated data structure, which it transmits to the media agent in the form of a single job. The media agent may process the single job in accordance with governing information management policies, and reports status and metadata to the storage manager. Thus, the protected data is absorbed into the information management system completely and efficiently, with minimal drain on the processing resources of the client and the other components.
