In order to save storage space and upload bandwidth, data deduplication, a method for removing duplicate copies of data, has been widely employed in cloud storage.Even when a file is held by a sizable number of users, there is only one copy for every file saved in the cloud.Deduplication systems enhance storage utilization while decreasing dependability as a result.The idea of a distributed reliable deduplication system is formalized for the first time in this publication.This research paper introduces an enhanced E-MLE deduplication strategy, characterized by heightened reliability.This upgraded deduplication framework comprises two distinct schemes: the static scheme and the dynamic scheme.Within this approach, deduplication verification occurs at the level of individual partial data units, rather than the entire dataset.This methodology ensures robust security by generating unique tags for each partial data unit, which are then stored in a deduplication decision tree.The primary advantage of this approach is its ability to generate tags from individual message segments.This, in turn, simplifies the process during client interactions and reduces the complexity associated with parity testing across the entire database.This efficiency improvement is applicable to the entirety of the data stored in the database.
