Resource replication in distributed environment produces issues of secondary storage. De-replication of resources is required when replication mechanism is hindered due to lack of secondary storage. This paper introduces de-replication approaches that depend upon last modification time, number of replica available and resource size. Comparative study shows that de-replication can be used to overcome the space overhead issue and reduces the de-replication time. Result shows that in case the space required is same but number of files to be de-replicated varies, de-replication time also varies depending on number of files to be de-replicated.
