Abstract

See full text

For calculation of digest segmentations for input data using similar data in a data deduplication system using a processor device in a computing environment, a stream of input data is partitioned into input data chunks. Similar repository intervals are calculated for each input data chunk. Anchor positions are determined between an input data chunk and the similar repository intervals, based on data matches between a previous input data chunk and previous similar repository intervals. Digest segmentations of the similar repository intervals are projected onto the input data chunk, starting at the anchor positions.
