In deduplication, data is searched for identical sections. One of these sections is stored and the rest are replaced with a reference pointing to the stored section. In this study, various aspects of deduplication were examined based on the literature. Special attention was given to the performance of deduplication and its improvement. In the review it was found that the diverse applications of deduplication require very different deduplication systems. The systems have to balance between the many aspects of performance: improving one aspect often weakens another. A computer program that deduplicates files was also implemented in this work. Its execution times were measured with different values of two variables. Values were found with which the program's execution times were generally the lowest.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-06-20T07:34:28Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-06-20T07:34:28Z (GMT).
