Abstract: Embodiments of the present invention provides systems for a tape library shelf. In one embodiment, a tape library shelf is disclosed including a chassis, which contains tape cartridge slots for storing one or more tape cartridges. The tape library shelf includes at least one tape drive module, a control unit, and a moving device coupled to the chassis. The moving device is operatively connected to the control unit to move the chassis according to instructions received from the control unit.

Abstract: Embodiments of the present invention disclose methods, computer program products, and systems for replicating data stored on a tape cartridge on one or more computing devices. In one embodiment, initiation of a replication sequence begins in response to at least one of: receiving a manual prompt of a user, loading of a first tape cartridge to be replicated into a first tape drive, receiving a request from a backup program, or occurrence of a predetermined time. When priming a first tape cartridge for writing of data, the first tape cartridge is configured for replication to a second tape cartridge. After loading the first tape cartridge into a first tape drive, data stored on the first tape cartridge can be directly transmitted from the first tape drive to a second tape drive in which the second tape cartridge is loaded without using an intermediate host computer system to facilitate data transfer.

Abstract: A tool for movement of a tape from a first tape library to a second tape library retrieving one or more tapes from one or more tape library frames in the first tape library. The tool inserts the one or more tapes into a passing tunnel module in the one or more tape library frames in the first tape library. The tool transfers the one or more tapes from the passing tunnel module in the one or more tape library frames in the first tape library to a passing tunnel module in one or more tape library frames in the second tape library.

Abstract: A cooperative data file coloring backup system includes a file color agent (FCA) and a file color storage cloud controller (FCSCC). The FCA assigns a color to a data file. The assigned color is associated with a highest projected data reduction factor achieved when backing up the data file from a host to one of various storage devices comprised within a data backup storage area network. The FCSCC maintains a list of file types and associated data reduction factors that are achieved during a backup of the file types and provides to the FCA a storage path from the host to a particular storage device within the storage area network associated with the highest data reduction factor and file type. The FCA may implement the storage path based upon the assigned color for each backup request received by the host.

Abstract: A tool for movement of a tape from a first tape library to a second tape library retrieving one or more tapes from one or more tape library frames in the first tape library. The tool inserts the one or more tapes into a fixed passing tunnel portion of a passing tunnel module in the one or more tape library frames in the first tape library. The tool moves the first tape library and the second tape library into a closed, non maintenance position. The tool transfers the one or more tapes from the fixed passing tunnel portion of the passing tunnel module in the one or more tape library frames in the first tape library to a flexible passing tunnel module of a passing tunnel module in one or more tape library frames in the second tape library.

Abstract: Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data. Undeduplicated data is stored with a checksum of an initial value. A stub pointing to the parent copy of the deduplicated data is stored with an additional checksum of a differing, additional initial value.

Abstract: Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a checksum of an initial value as a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with an additional checksum of a differing, additional initial value as a second CRC seed.

Abstract: For adding cooperative file coloring protocols in a data deduplication system using a processor device in a computing environment, a preferred character is represented for file coloring in a file using a code selected from a multiplicity of codes that represent a variety of contexts. The original meaning of the preferred character is retained when representing the preferred character for the file coloring by the code selected from the multiplicity of codes.

Abstract: Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with a second CRC seed. Subsequent to reading the deduplicated data, the first CRC seed is associated with the undeduplicated data, and the second CRC seed is associated with the stub. A CRC check is performed using one of the first and second CRC seeds. If the CRC check is positive, an I/O operation is allowed to proceed. If the CRC check is negative, an additional CRC check is performed using another one of the first and second CRC seeds.

Abstract: A pass-through mechanism that couples a first linear tape library string to a second linear tape library string is maintained. A first robotic assembly associated with the first linear tape library string places a tape from the first linear tape library string into the pass-through mechanism. The pass-through mechanism moves the tape to a position where the tape can be removed by a second robotic assembly associated with the second linear tape library string. The second robotic assembly removes the tape from the pass-through mechanism and places the tape into the second linear tape library string.
