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.

System and method for providing encryption in storage operations in a storage network, such as for use by application service providers that provide data storage services

Described herein are systems and methods for multiplexing pipelined data for backup operations. Various data streams are combined such as by multiplexing by a multiplexing module. The multiplexing module combines the data from the various data streams received by receiver module(s) into a single stream of chunks. The multiplexing module may combine data from multiple archive files into a single chunk. Additional modules perform other operations on the chunks of data to be transported such as encryption, compression, etc. The data chunks are transmitted via a transport channel to a receive pipeline that includes a second receiver module and other modules. The data chunks are then stored in a backup medium. The chunks are later retrieved and separated such as by demultiplexing for restoring to a client or for further storage as auxiliary copies of the separated data streams or archive files.

Systems and methods for combining data streams in a storage operation

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.

System and method for performing auxiliary storage operations

Methods and systems are described for verifying stored data by receiving a first set of metadata associated with a first set of stored data, generating a second set of metadata associated with a second set of stored data which is associated with the first set of stored data, and comparing the first set of metadata and second set of metadata. Alternatively, the storage system can also generate a first set of metadata associated with a first set of stored data, generate a second set of stored data which is a copy of the first set of stored data, generate a second set of metadata associated with the second set of stored data, and compare the first set of metadata and the second set of metadata.

Systems and methods for stored data verification

A system and method for operating a storage library. The system comprises a management server, a media agent connected to the management server, a library connected to the media agent and a database connected to the management server. The management server controls the media agent to monitor for the addition or removal of a piece of media in the library. When the media agent determines that the piece of media has been added to the library or removed from the library, the media agent causes the library to read a media label stored as data on the piece of media, the media label including an identifier identifying the piece of media. When a backup or restore is performed, the system checks the media label to ensure that the correct media is being used. Inventory procedures are disclosed. Media labels are stored in a database along with an indication of the corresponding slot where the media is stored, a time when the label was put on the medium, and a confidence parameter indicating how confident the system is that the particular medium is stored in the respective slot.
