Abstract: Certain embodiments disclosed herein reduce or eliminate a communication bottleneck at the storage manager by reducing communication with the storage manager while maintaining functionality of an information management system. In some implementations, a client obtains information for enabling a secondary storage job (e.g., a backup or restore) from a storage manager and stores the information (which may be referred to as job metadata) in a local cache. The client may then reuse the job metadata for multiple storage jobs reducing the frequency of communication with the storage manager. When a configuration of the information management system changes, or the availability of resources changes, the storage manager can push updates to the job metadata to the clients. Further, a client can periodically request updated job metadata from the storage manager ensuring that the client does not rely on out-of-date job metadata.

Abstract: In certain systems disclosed herein, a distributed data monitoring and management system is provided that can replicate a distributed storage environment. The distributed data monitoring and management system can intelligently and automatically configure data access nodes to form a structure that matches the distributed storage environment. By matching the structure of the distributed storage environment, the distributed structure of the data may be maintained, enabling the data to be backed up from and/or restored to the distributed storage environment and/or migrated to another distributed storage environment without altering the distribution of the data. Further, embodiments herein enable the monitoring of nodes within the system and transfer of data from a non-distributed environment to a distributed storage environment. Thus, in some cases, an entity can migrate data from a local storage structure to a network-based distributed storage structure.

Abstract: An information management system is described herein that implements a slim migration of backup or other secondary copy data. For example, upon receiving a request to migrate primary data corresponding to secondary copy data from one computing system to a network-accessible folder or to another computing system, the information management system can migrate at least a portion of the data as primary data and/or at least a portion of the data as stubs. The use of the stub may be transparent to the user such that the user perceives the stub as being the actual data (e.g., when displayed). Because the stub identifies data included in the secondary copy of data, but is not the actual data itself, a stub may have a smaller file size than the actual data, providing increased data migration speeds.
