  • Patent number: 8140779
    Abstract: A backup method relies on a single secondary storage device, such as a tape storage device, which emulates multiple secondary storage devices. The emulated secondary storage devices are coupled to data sources. Data which is received from the data sources is tagged with respective unique identifiers, interleaved and stored on a removable storage medium, such as a tape. This facilitates maximum usage of the media access bandwidth of the single secondary storage device.

  • Publication number: 20110173407
    Abstract: A data storage system comprising a server computer and a data storage medium. The server computer includes an interface, such as an iSCSI interface, for communicating with a host computer. In response to receiving data from the host computer, the server computer determines whether or not the host computer has access to a virtual data storage device. If the host computer does not have access to a virtual data storage device, the server computer provides a virtual data storage device for access by the host computer, the virtual data storage device employing at least a portion of the data storage medium such that data stored to the virtual data storage device are stored to the portion of the data storage medium.

  • Publication number: 20070088899
    Abstract: In a tape drive apparatus commonly shared by a plurality of host devices coupled to the tape drive apparatus over a host port, access control is provided. Each host device is identified by a host address. The tape drive apparatus comprises a data transfer unit for transferring data between a loaded tape medium and the tape drive apparatus. A command for registering a host address of one of the plurality of host devices in the tape drive apparatus for the purpose of authorising access is received over a management port. A command comprising data to be stored on the tape medium is received from a requesting host device over the host port. The host address of the requesting host device is derived from the command received over the host port. The host address of the requesting host device is verified against the host address registered in the tape drive apparatus to determine whether or not the requesting host device has access authorisation.

  • Publication number: 20050246509
    Abstract: A validity time interval for backup data of a data backup operation is determined. The validity time interval is limited, e.g., by an expiration date and/or an activation date. Validity date indicating the validity time interval is stored in non-volatile memory of the tape cartridge, such as a cartridge memory, when the backup data is written to the tape cartridge by the tape drive. Recovery of the backup data from the tape drive is only possible if recovery is performed within the validity time interval, to provide an efficient way to assure tape rotation.
