In some examples, the system determines a media component to be exported, determines the media component is in the media library for a specific process, and exports the media component after the process is completed.

Abstract: Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices (e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.

Abstract: A system according to certain embodiments associates a signature value corresponding to a data block with one or more data blocks and a reference to the data block to form a signature/data word corresponding to the data block. The system further logically organizes the signature/data words into a plurality of files each comprising at least one signature/data word such that the signature values are embedded in the respective file. The system according to certain embodiments reads a previously stored signature value corresponding to a respective data block for sending from a backup storage system having at least one memory device to a secondary storage system.

Abstract: The library server according to certain aspects can manage the use of tape drives according to the data requirements of different storage operation cells. The library server according to certain aspects can also facilitate automatic management of tape media in a tape library by allocating the tapes and slots to different cells. For instance, the library server can manage the positioning and placement of the tapes into appropriate slots within the tape library.

Abstract: In accordance with embodiments of the invention, a method is provided for performing a storage operation in a pipeline storage system in which one or more data streams containing data to be stored are written into data chunks. The method includes generating an encryption key associated with a first archive file to be stored when encryption is requested for the storage operation, encrypting the archive data from the data stream using the encryption key to create an encrypted data chunk when a data stream containing the archive file is processed in the pipeline storage system, storing the encrypted data chunk on a storage medium, and storing the encryption key in a manner accessible during a restore operation of the encrypted data chunk.

Abstract: A content alignment system according to certain embodiments aligns a sliding window at the beginning of a data segment. The content alignment system performs a block alignment function on the data within the sliding window. A deduplication block is established if the output of the block alignment function meets a predetermined criteria. At least part of a gap is established if the output of the block alignment function does not meet the predetermined criteria. The predetermined criteria is changed if a threshold number of outputs fail to meet the predetermined criteria.

Abstract: Content-aware systems and methods for improving de-duplication, or single instancing, in storage operations. In certain examples, backup agents on client devices parse application-specific data to identify data objects that are candidates for de-duplication. The backup agents can then insert markers or other indictors in the data that identify the location(s) of the particular data objects. Such markers can, in turn, assist a de-duplication manager to perform object-based de-duplication and increase the likelihood that like blocks within the data are identified and single instanced. In other examples, the agents can further determine if a data object of one file type can or should be single-instanced with a data object of a different file type. Such processing of data on the client side can provide for more efficient storage and back-end processing.

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.

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: Various systems and methods may be used for performing data storage operations, including content-indexing, containerized deduplication, and policy-driven storage, within a cloud environment. The systems support a variety of clients and cloud storage sites that may connect to the system in a cloud environment that requires data transfer over wide area networks, such as the Internet, which may have appreciable latency and/or packet loss, using various network protocols, including HTTP and FTP. Methods for content indexing data stored within a cloud environment may facilitate later searching, including collaborative searching. Methods for performing containerized deduplication may reduce the strain on a system namespace, effectuate cost savings, etc. Methods may identify suitable storage locations, including suitable cloud storage sites, for data files subject to a storage policy.
