AN ANALYSIS AND COMPARISON OF DATA DEDUPLICATION APPROACHES TO EFFICIENT STORAGE

Abstract

When the volume of digital data increases, it requires more storage space and efficient technique to effectively handle these huge data. While handling huge amount of data, duplicacy is unavoidable. Backup of duplicate data increases the storage time and consumes more resources. Data deduplication is one of the essentially used techniques in storage environment that employs various techniques to manage duplicate data efficiently, which removes redundant data; minimizes bandwidth and optimizes storage utilization. This paper reviews various deduplication techniques and evaluation process used to measure their performance. Also compares and correlates security related to data deduplication techniques.
