Abstract: A distributed, deduplicated storage system according to certain embodiments is arranged in a parallel configuration including multiple deduplication nodes. Deduplicated data is distributed across the deduplication nodes. The deduplication nodes can be networked together and communicate with one another according using a light-weight, customized communication scheme (e.g., a scheme based on FTP or HTTP). In some cases, deduplication management information including deduplication signatures and/or other metadata is stored separately from the deduplicated data in deduplication management nodes, improving performance and scalability.

Abstract: Systems and methods for providing automated problem reporting in elements used in conjunction with computer networks are disclosed. The system comprises a plurality of elements that perform data operations and a reporting manager or monitor agent which monitors the elements and data operations. Upon detection of hardware or software problems, the reporting manager or monitor agent automatically communicates with elements affected by the problem to gather selected hardware, software, and configuration information, analyzes the information to determine causes of the problem, and issues a problem report containing at least a portion of the selected information. The problem report is communicated to a remote monitor that does not possess access privileges to the elements, allowing automated, remote monitoring of the elements without compromising security of the computer network or elements.

Abstract: An illustrative pseudo-file-system driver uses deduplication functionality and resources in a storage management system to provide an application and/or a virtual machine with access to a locally-stored file system. From the perspective of the application/virtual machine, the file system appears to be of virtually unlimited capacity. The pseudo-file-system driver instantiates the file system in primary storage, e.g., configured on a local disk. The application/virtual machine requires no configured settings or limits for the file system's storage capacity, and may thus treat the file system as “infinite.” The pseudo-file-system driver intercepts write requests and may use the deduplication infrastructure in the storage management system to offload excess data from local primary storage to deduplicated secondary storage, based on a deduplication database. The pseudo-file-system driver also intercepts read requests and in response may restore data from deduplicated secondary storage to primary storage, also based on the deduplication database.

Abstract: Techniques for providing data preview before recalling large data files are disclosed. In one aspect, a data file is made accessible while being offline by converting the data file from a native format to a preview format, storing the data file in the preview format in a primary storage that is locally available and moving, after the conversion to the preview format, the data file in the native format to a secondary storage. When a viewing request is received for the data file, the data file in the preview format is displayed to fulfill the viewing request.

Abstract: Techniques for providing shared access to, e.g., a small computer system interface (SCSI) storage device in a computer network include providing an operational mode on SCSI interfaces with a first media agent and a second media agent such that, in response to inquiry messages on the SCSI interfaces, the SCSI storage device appears as a SCSI target device to the first media agent and the second media agent and mapping data operations between the first media agent and the SCSI storage device and the second media agent and the SCSI storage device to logically unique channel numbers for the first media agent and the second media agent to perform data storage operations over their respective SCSI interfaces by concurrently sharing the SCSI storage device.

Abstract: A method and system for creating an index of content without interfering with the source of the content includes an offline content indexing system that creates an index of content from an offline copy of data. The system may associate additional properties or tags with data that are not part of traditional indexing of content, such as the time the content was last available or user attributes associated with the content. Users can search the created index to locate content that is no longer available or based on the associate attributes.

Abstract: Systems and methods integrate disparate backup devices with a unified interface. In certain examples, a management console manages data from various backup devices, while retaining such data in its native format. The management console can display a hierarchical view of the client devices and/or their data and can further provide utilities for processing the various data formats. A data structure including fields for storing both metadata common to the client device data and value-added metadata can be used to mine or process the data of the disparate client devices. The unified single platform and interface reduces the need for multiple data management products and/or customized data utilities for each individual client device and provides a single pane of glass view into data management operations. Integrating the various types of storage formats and media allows a user to retain existing storage infrastructures and further facilitates scaling to meet long-term management needs.

Abstract: A stand-alone, network accessible data storage device, such as a filer or NAS device, is capable of transferring data objects based on portions of the data objects. The device transfers portions of files, folders, and other data objects from a data store within the device to external secondary storage based on certain criteria, such as time-based criteria, age-based criteria, and so on. A portion may be one or more blocks of a data object, or one or more chunks of a data object, or other segments that combine to form or store a data object. For example, the device identifies one or more blocks of a data object that satisfy a certain criteria, and migrates the identified blocks to external storage, thereby freeing up storage space within the device. The device may determine that a certain number of blocks of a file have not been modified or called by a file system in a certain time period, and migrate these blocks to secondary storage.
