Abstract: A scalable approach is disclosed for processing auxiliary-copy jobs in a storage management system by using distributed media agent resources instead of a centralized storage manager. Enhanced media agents coordinate and control auxiliary-copy jobs and tap the storage manager to reserve data streams and provide job-specific metadata on demand. An enhanced storage manager may initially select a media agent as “coordinator” to coordinate auxiliary-copy jobs with any number of other media agents, which act as “controllers.” A coordinator media agent is generally responsible for obtaining data stream reservation information from the storage manager and assigning auxiliary-copy jobs to respective controller media agents, based on the components involved in the respective reserved data streams.

Abstract: An information management system implements a media agent that communicates with a network area storage (NAS) device to receive secondary copy data that has been backed-up by the NAS. The secondary copy data may include primary data managed or maintained by the NAS. The secondary copy data may be in a proprietary format or other data format specific to the NAS. The NAS may prepare metadata or other information about the secondary copy data that informs the media agent as to the contents of the secondary copy data. The media agent may segment the secondary copy data into one or more backup chunks for storing in a secondary storage device. In addition, each of the backup chunks may be associated with backup chunk metadata, where the backup chunk metadata includes information that describes certain information stored by a corresponding backup chunk.

Abstract: A storage system according to certain embodiments includes a client-side repository (CSR). The CSR may communicate with a client at a higher data transfer rate than the rate used for communication between the client and secondary storage. During copy operations, for instance, some or all of the data being backed up or otherwise copied to secondary storage is stored in the CSR. During restore operations, copies of the data stored in the CSR is accessed from the CSR instead of from secondary storage, improving performance. Remaining data blocks not stored in the CSR can be restored from secondary storage.

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: A method and system for providing information management of data from hosted services receives information management policies for a hosted account of a hosted service, requests data associated with the hosted account from the hosted service, receives data associated with the hosted account from the hosted service, and provides a preview version of the received data to a computing device. In some examples, the system indexes the received data to associate the received data with a user of an information management system, and/or provides index information related to the received data to the computing device.
