    Abstract: Systems and methods are provided herein for automatically configuring newly installed secondary storage computing devices and managing secondary storage computing devices when one or more become unavailable. For example, a storage manager can then detect the computing resources available to the newly installed secondary storage computing device, assign a role to the newly installed secondary storage computing device based on the detected computing resources, configure the newly installed secondary storage computing device with deduplication and storage policies used by the other secondary storage computing devices, re-partition secondary storage devices to allocate memory for the newly installed secondary storage computing device, and instruct other secondary storage computing devices to replicate their managed data such that the newly installed secondary storage computing device has access to the replicated data.

    Abstract: Described are systems and methods for storing a variable number of instances of data objects (e.g., 1, 2, 3, or up to N−1 instances, where N is the number of instances of the data object included in primary data) in secondary storage across a data storage network. In some examples, a system for storing a variable number of instances of data objects includes, one or more computing devices storing a set of data objects and multiple storage devices distinct from the one or more computing devices. Each of the multiple storage devices is configured to store at least a single instance of a data object. The system also includes a database configured to store information associated with the data objects. This information includes substantially unique identifiers for the data objects and, for each of the data objects, a number of instances of the data object stored on the multiple storage devices.

    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.
