摘要： A system and method for watermarking data that includes a client device, a file system manager, a file server, and a storage network. The file system manager sets watermark control information. The file server includes: (1) a file writing process including a file watermark examination procedure and an action procedure, the action procedure determining an action based on a result of the file watermark examination; and (2) a file reading process including a watermark definition procedure, a file handle/memory preparation procedure, a file data copy procedure, and a watermark insertion procedure. During a read request the watermark definition procedure determines whether a file to be read is to be watermarked based on a user at the client device that requested to read the file. Whether a write request is processed or not is based on the user and whether the file to be written contains a watermark.

摘要： Data stored in a data storage system is hashed to generate a hash value. The hash value and a request for a time stamp are then sent to a time stamping authority. A time stamp token and/or a time stamp certificate is received from the time stamping authority. The time stamp token includes a time stamp and the hash value, and may be encrypted using a private key of the time stamping authority. The time stamp token and/or time stamp certificate is then stored with, for example, a reference to the data being stored in the data storage system. The time stamp token and/or time stamp certificate may then be used to validate the data being stored and the time stamp.

摘要： A method for operating a storage system configured to provide a Write Once and Read Many (WORM) function includes receiving a first command at a storage subsystem from a host. At least a portion of the first command is stored on a WORM storage device coupled to the storage subsystem. A second command is received at the storage subsystem. The second command is examined using a command filter, the filter being provided with a predetermined rule for filtering selected types of commands. At least a portion of the second command is stored if the second command satisfies the predetermined rule. The WORM storage device is used to verify the WORM function of the storage system.

摘要： A secure data mirroring capability in a storage system includes encrypting data blocks in a primary volume in preparation for a data mirroring operation. The encrypted data blocks are mirrored to a secure secondary volume. Host systems provide keys from which encryption keys are produced for encrypting the data blocks. Access to data on the secure secondary volume requires decryption using the key that was used to produce the encrypted data blocks.

摘要： A method of generating and linking programs required in a data linkage system to link data among a plurality of computer systems, for example a mainframe and an open system, is provided. In the data linkage system with a means for data transfer via a storage device, a program generation tool is prepared in the open system. The program generation tool reads a data stream definition and generates an intermediate file area securing program and a data linkage program A, both run on the mainframe, and a data linkage program B run on the open system. These programs are linked with one another. The intermediate file area securing program and the data linkage program A are transferred to the mainframe where they are executed.

摘要： A method and a system for implementing the method are disclosed relating to archival storage of information in large numbers of disk units. The reliability of the stored information is checked periodically using data verification operations whose results are saved. These results establish the veracity of the data and enable compliance with various regulatory requirements. The techniques described enable the use of low cost disk drive technology, yet provide high assurance of data veracity. In a typical system, management information storage is provided in which data entries are associated with each of the disk drives to provide information with respect to the condition of the data on that drive and its last verification. The data verification operations are performed on the data during time periods when I/O accesses are not required.

摘要： A method for copying data to multiple remote sites includes transmitting data from a first volume in a primary storage system to a back-up volume provided in a secondary storage system. The primary storage system is located at a primary site, and the secondary storage system is located at a first remote site from the primary site. The data from the first volume in the primary storage system is copied to a second volume in the primary storage system using a point in time (PiT) as a reference point of time for the copying. The second volume is provided with a first time consistent image of the first volume with respect to the reference point of time. The data from the second volume in the primary storage system is transferred to a third volume in a ternary storage system at a second remote site. The third volume is provided with a second time consistent image of the second volume with respect to the reference point of time, where the second time consistent image is a mirror image of the first time consistent image. The data from the third volume is transferred to a fourth volume in the ternary storage system. The fourth volume is provided with a third time consistent image. In the ternary storage, either of the third volume or fourth volume can always keep time consistent image of the first volume.

摘要： A system is provided for storage of journal data from a primary site to a secondary site with a predefined quality of service. In one implementation, the primary storage system stores information for updating data stored on the primary disk array in the form of a history of updates made to the data. The primary storage system is configured to transfer this journal information to the secondary storage system. The user can specify the quality of service desired using a variety of measures, for example, a recovery point objective or a recovery time objective. In response, a copy manager within one of the storage systems determines the capacity of the various primary and secondary volumes, and determines the copy rate available, typically dependent upon the bandwidth between the primary and secondary systems. The copy manager then copies journal data to the remote site where it is stored.
