Abstract : In the file system level Disaster Recovery (DR) configurations with asynchronous data replication, synchronized
peer snapshots are taken periodically based on Recovery Point Objective (RPO)at local and remote file systems. Once local
file system has hit disaster, the remote file system is restored to most recent snapshot for data consistency. The time to
restore remote file system contributes to Recovery Time Objective (RTO) which is not consistent and not predictable. In this
paper a new efficient procedure is described for taking snapshots based on distinct data blocks modified, defined as
“Recovery Data Blocks Objective” (RDBO).In our experiments it is observed that the RTO is linearly proportional to the
distinct data blocks modified from most recent snapshot. This helps to accurately and consistently estimate the RTO based
on RDBO defined for file systems.
