De-replication: A Dynamic Memory Aware Mechanism

Keywords: De-replication; Distributed Systems; Replication

Abstract:
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. De-replication time will be more for case having large number of files. With the proposed approach, if file size increases by the multiple of 7, de-replication time will get increase just by the multiple of 1.5. This shows that de-replication time is decoupled from size of files that are de-replicated on the fly dynamically and does not increase proportionally with respect to file size.
