摘要： A system and a computer program product are disclosed for eliminating access to data on removable storage media of a removable storage media cartridge. The system comprises a computer configured to send to a data storage drive a command to eliminate access to data on a removable storage media cartridge, and send to the data storage drive a command to shred at least one key in response to the command, where shredding the at least one key eliminates access to the data on the removable storage media cartridge. A determination to eliminate access to the data on the removable storage media cartridge is based on a number of read and/or write errors encountered for the removable storage media cartridge.

摘要： Provided are a computer program product, system, and method for merging multiple point-in-time copies into a merged point-in-time copy. A repository maintains a full copy of the source data and point-in-time copies at point-in-times of the source data. Each of the point-in-time copies have change information indicating changed data in the source data that changed between the point-in-time of the point-in-time copy and a subsequent point-in-time and changed point-in-time data comprising data in the source data as of the point-in-time of the point-in-time copy indicated in the change information as changed. At least two selected of the point-in-time copies in the repository are merged into a merged point-in-time copy by: forming merged change information in the merged point-in-time copy indicating changed data indicated in change information for the selected point-in-time copies; and forming merged changed data in the merged point-in-time copy from the changed data in the selected point-in-time copies.

摘要： Provided are a computer program product, system, method, and data structure for using variable length code tables to compress an input data stream to a compressed output data stream. If a number of consecutive data units in the input data stream match the number of consecutive data units in a history buffer of previously received data units in the input data stream, a copy pointer symbol is generated indicating the copy pointer symbol referencing previously received data units in the history buffer and indicating a location of a start of the consecutive data units in the history buffer. A determination is made of an encoding of the number. Indication is made in the generated copy pointer symbol the determined encoding of the number and the copy pointer symbol is outputted in the compressed output data stream.

摘要： According to one embodiment, a method includes storing instances of a file in a first storage tier and a second storage tier of a storage system, wherein the second storage tier uses less expensive and/or slower-to-access storage media than the first storage tier. Each instance of the file on the first and second storage tier is associated with a unique program identifier (UPI). A request to access the file or instance thereof is received from a user in a group of users, and a UPI associated with an instance of the file that exists on the first storage tier is searched for. Remote access to the instance of the file on the first storage tier is provided to the user requesting access to the file. Additional embodiments are also presented.
