Abstract

This paper sets forth “Snapshot Lifecycle Management”, an innovative way to manage snapshot data rather than using Information Lifecycle Management. There are two major problems occurs in snapshot management by ILM: “inappropriate migration” and “redundancy”. SLM manages snapshot data elaborately according to its characteristic to eliminate the twin problems. In addition, this paper also proposes “Snapshot Support for iLVM (Internet Logical Volume Management)”, integrating SLM into iLVM. Use Copy-on-Write technique to update data between local site and remote site and replace the “Remote Region Time Parity” scheme in remote data checking.
