Abstract

Segment sizes are controlled by setting the size of a segment boundary in a hash-based deduplication system. A subsequence of size K of a sequence of characters S is set. An increasing sequence of n probabilities and a corresponding sequence of n decreasingly restrictive logical tests are chosen to be applied on the sequence of characters S. Segment boundaries are set by using the sequence of the decreasingly restrictive logical tests by deciding to declare a segment boundary at a current position if one of the sequence of the decreasingly restrictive logical tests, with a corresponding probability of the sequence of n probabilities, returns a true value when applied on the sequence of characters S.
