    Abstract: An information management system according to certain aspects allows users to share a portion of a file (e.g., a document) stored in secondary storage. The user may specify a portion of a secondary storage file to share and send a link to the portion to another user. The other user can access the shared portion from the link, and just the shared portion may be restored from secondary storage. The system according to certain aspects provides a native view of secondary storage data on a client computing device. The index data and/or metadata relating to secondary storage data may be stored in native application format for access via the native source application.

    Abstract: A system according to certain aspects may include a secondary storage controller computer configured to: in response to a first instruction to obtain a first secondary copy of a first data set from a secondary storage device(s), the first instruction associated with a first restore operation: instantiate a first restore thread on a processor of the secondary storage controller computer; using the first restore thread, retrieve the first secondary copy from the secondary storage device(s); and forward the retrieved first secondary copy to a primary storage subsystem for storage; and in response to a second instruction to obtain a second secondary copy of a second data set from the secondary storage device(s), the second instruction associated with a second restore operation: using the first restore thread, retrieve the second secondary copy from the secondary storage device(s); and forward the retrieved second secondary copy to the primary storage subsystem for storage.

    Abstract: The data storage system according to certain aspects can implement partial file restore, where only a portion of the secondary copy of a file is restored. Such portion may be designated by one or more application offsets for the file. The system may provide an in-chunk index that includes mapping information between the application offsets and the secondary copy offsets. Chunks may refer to logical data units in which secondary copies are stored, and the in-chunk index for a chunk may be stored in secondary storage with the chunk. Because the mapping information may not be provided at a fixed interval, the system can search through application offsets in the in-chunk index to locate the secondary copy offset corresponding to the portion application offset(s). In this manner, the system may restore the designated portion of the secondary copy in a fast and efficient manner by using the in-chunk index.
