摘要： A method for performing write calibrations on holographic storage media is disclosed. Initially, five identical and known calibration holograms are written on a holographic storage medium, in which three of the five calibration holograms are written with different laser power and three of the five calibration holograms are written with different time durations. A matched filter is then utilized to determine a cross-correlation between the five calibration holograms read from the holographic storage medium and their corresponding ideal calibration holograms previously stored within a memory device within the holographic storage drive. A least-squares fit of an ellipsoidal parabola to the cross-correlations is subsequently calculated to yield an optimal laser write power level and an optimal duration for a laser write pulse.

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.
