    Abstract: A system and method for transferring data in a library storage system (200). The library storage system (200) comprises a management server (23) including a storage policy (19). A media agent (27) is connected to the management server (23). A plurality of storage media (58-68) and a data source (25) are connected to the media agent (27). The data source (25) is divided into at least a first and a second portion of data. The portions of data are transferred from the data source (25) to a first (58) and second (62) primary storage medium using a first (54) and a second (56) data stream respectively. The media agent (27) then causes the first and second portion of data to be transferred from the first (58) and second (62) storage medium to a third auxiliary storage medium (70) using a third combined data stream (54a, 56a).

    Abstract: A system for archiving data objects using secondary copies is disclosed. The system creates one or more secondary copies of primary copy data that contains multiple data objects. The system maintains a first data structure that tracks the data objects for which the system has created secondary copies and the locations of the secondary copies. To archive data objects in the primary copy data, the system identifies data objects to be archived, verifies that previously-created secondary copies of the identified data objects exist, and replaces the identified data objects with stubs. The system maintains a second data structure that both tracks the stubs and refers to the first data structure, thereby creating an association between the stubs and the locations of the secondary copies. Notably, the system archives data objects in primary copy data without creating an additional or other secondary copy of the data objects. Instead, the association between the two data structures allows stubs to point to or refer to the previously-created secondary copy of the data objects. Accordingly, the existence of the previously-created secondary copy of the data objects allows the system to forego creating an additional or other secondary copy of the data objects, thereby saving resources.

    Abstract: A system and method for using a snapshot as a data source is described. In some cases, the system stores a snapshot and an associated data structure or index to storage media to create a secondary copy of a volume of data. In some cases, the associated index includes application specific data about a file system or other application that created the data to identify the location of the data. The associated index may include three entries, and may be used to facilitate the recovery of data via the snapshot.

    Abstract: Systems and methods for protecting data in a tiered storage system are provided. The storage system comprises a management server, a media management component connected to the management server, a plurality of storage media connected to the media management component, and a data source connected to the media management component. Source data is copied from a source to a buffer to produce intermediate data. The intermediate data is copied to both a first and second medium to produce a primary and auxiliary copy, respectively. An auxiliary copy may be made from another auxiliary copy. An auxiliary copy may also be made from a primary copy right before the primary copy is pruned.

    Abstract: The invention provides a method and system for transferring storage media (140) scheduled for export from a storage device(120). The storage media (140) is identified according to retention characteristics for export, and placed in a location near to the storage device exit point prior to it scheduled export out of the storage device to offsite storage. The storage device interfaces with the storage management system used at the offsite storage to provide tracking of the storage media at the offsite location. The location of the media is tracked within the storage system and at the offsite storage, for administrative, reporting or other uses.

    Abstract: The present invention provides systems and methods for extending media retention. Methods are provided in which a set of aging preferences are obtained. Data elements of a data set stored on storage media are evaluated against the aging preferences to determine whether each of the data elements satisfy the aging preferences. Each of the data elements that is determined to satisfy the aging preferences is aged. Aging can include freeing a portion of storage media, previously used to store a data element, for other storage usage
