摘要： A block based storage system and method uses RAM memory to implement the buffers and is made redundant by replicating the buffer cache to an in-memory buffer cache on a separate caching unit. Replication can be done using one or more parity schemes (e.g. RAID 1, RAID 5, RAID 6) and/or other replication processes. In case of a power failure of the storage unit, the buffer cache is kept on the caching unit and the buffer cache is restored when the storage unit is available again, and normal operation is resumed

摘要： A system and method for efficiently backing up and restoring computer files to a central storage system. A hashing key is computed for each file to be backed up on a target computer. The hashing key is compared to a list of hashing keys stored locally to see if the local file has been previously backed up. If the hashing key is not listed locally, then the hashing key is compared to a list of hashing keys of centrally backed up files. Only if the hashing key is not present in both the local and the central list is the file backed up. Backed up files may be renamed to their hashing key for further efficiencies.

摘要： A data backup system can be operable to determine whether to send a data file segment to backup storage. The data backup system can comprise a comparator operable to compare a boundary parameter of a candidate segment proposed for sending to backup storage to a boundary parameter of a previously stored segment to determine whether the candidate segment potentially corresponds to the previously stored segment. The data backup system can also comprise a comparator operable, if it is determined that the candidate segment potentially corresponds to the previously stored segment, to compare a checksum value for the candidate segment to a checksum value for the previously stored segment to determine whether the candidate segment has previously been stored to the second location. A storage engine can be provided to send to backup storage a segment determined not to have previously been stored. Thereby a single instance store can be implemented whereby a modified segment can be identified and a segment boundary adjusted to avoid re-storage of previously stored data.

摘要： A method and system for performing securing and controlling of a network using content identification of files in a network having a central infrastructure and local computing devices is presented. The method comprises calculating a hash value of a new file created or received on a local computing device, transmitting the hash value to the central infrastructure, comparing the hash value with a previously determined hash value stored in a database on the central infrastructure to determine whether the file is new to the network and if the file is new to the network, checking the file content with a content identifying engine, installed and updated on the central infrastructure. Content attributes are determined for the files which allow to perform appropriate actions on the local computing devices according to policy rules.
