In one example, the cached entities are session locks and the object is a file system object.

Abstract: A data integrity verification method and system based on a root random number to ensure secure distributed data storage on a public cloud. A new root random number can be generated in response to receiving a file for storage to the public cloud. A unique random number tag for each data chunk associated with the file can be calculated via a shift operation and the tag can be added to the data chunk. A hash function (message digests) can be then generated and concatenated with the data chunk and the random number tag. The data chunk in conjunction with the hash and the random number tag can be encrypted by an encryption module and stored to the public cloud in order to provide multiple levels of security with respect to the distributed public cloud storage. Upon file retrieval, the encryption module decrypts all data chunks and recalculates the hash in order to verify the data integrity of the file.

The data fingerprint thereby efficiently provides an indication of the contents of the data object, so that comparing data fingerprints can determine if the data objects are different if the corresponding fingerprints are different.

Mappings, or correlations, between chunks of the metadata that originated from a particular data source and the metadata clusters may be determined and displayed, e.g., on a graphical user interface.

An inconsistency may be an incorrect mapping, the mapping of more than one of the metadata chunks that originated from the same data source to the same metadata cluster, or that one or more of the metadata chunks have not been mapped to a metadata cluster. The mappings may then be edited so as to remove detected inconsistencies.

Abstract: A source application reads a body of data in data block sized units and calculates a checksum value for each data block before sending the data block, the calculated checksum value and the identifier. Upon receipt, a destination application independently calculates a checksum value for each received data block and compares the two checksums. Non-matching checksums indicate a network-induced error in the data block. Identifiers for the erroneous data blocks are transmitted to the source application after all of the data blocks have been initially transmitted. The source application thereafter resends only those data blocks identified. The destination application repeats the process of comparing checksums and transmitting identifiers to the source application until all of the data blocks of the body of data have been correctly received, and then uses the data blocks to recreate the body of data.
