Abstract
Resource replication in distributed environment produces issues of secondary storage. Dereplication of resources is required when replication mechanism is hindered due to lack of secondary storage. This paper introduces dereplication approaches that depend upon last modification time, number of replica available and resource size. Comparative study shows that dereplication can be used to overcome the space overhead issue and reduces the dereplication time. Result shows that in case the space required is same but number of files to be dereplicated varies, dereplication time also varies depending on number of files to be dereplicated. Dereplication time will be more for case having large number of files. Also if file size is increasing by 7 times, increase in dereplication time is by 1.5 times. This shows that dereplication time is decoupled from size of files that are dereplicated on the fly dynamically and does not increase proportionally with respect to file size.
