摘要： A velocity calculator performs high-order calculations of servo frame velocities of a storage media, particularly tape and disk. The velocity calculator employs a servo frame indexing module for generating a first-order preceding servo frame velocity signal indicative of a first-order calculation of a preceding servo frame velocity including a first-order preceding servo frame error term based on first-order current servo frame velocity signal indicative of a first-order calculation of a current servo frame velocity including a first-order current servo frame error term. The velocity calculator further employs a velocity estimating module for generating a higher-order current servo frame velocity signal indicative of a second or higher order velocity calculation of the current servo frame velocity including a higher-order current servo frame error term based on the first-order preceding servo frame velocity signal and the first-order current servo frame velocity signal.

摘要： A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.

摘要： In a method of and a system for deduplicating backed-up data backup clients create respective backup tables comprising a list of files and respective file types to be backed up. A backup server receives backup tables from the backup clients. The backup server merges the received backup tables to form a merged backup table. The backup server sorts the merged backup table according to file type from a file type yielding a best deduplication ratio to a file type yielding a worst deduplication ratio, thereby forming a sorted backup table. The backup server requests the files listed in the sorted backup table, in order, from the backup clients. The backup server deduplicates files received from the backup clients, in order, using deduplication parameters optimized according to file type. The method calculates an updated deduplication ratio for each deduplicated file type. Examples of deduplication parameters include chunking techniques and hashing techniques.

摘要： A method of a computer system controlling writing of data to a removable medium includes communicating a unique identification (ID) of the removable medium to the computer system, intercepting a write operation to the removable medium, communicating with a security server via a network interface and a network, sending the unique ID of the removable medium along with a list of data files being written, and determining if the data files are allowed to be written to the removable medium using the security server. The determination includes determining a security level of the data files, determining a security level of the removable medium based on the unique ID, determining if the security level of the data files is higher than the security level of the removable medium, and sending a message to the computer system via the network and instructing the computer system to allow or prevent writing the data files. The data files are allowed to be written to the removable medium if the security level of the data files is equal or lower than the security level of the removable medium. The data files are prevented from being written to the removable medium if the security level of the data files is higher than the security level of the removable medium.
