Claim 9:
10. A non-transitory computer readable medium including program instructions for execution on a processor, the program instructions configured to:
create one or more protection rules (PR) for retaining a number of common snapshots across nodes of a multi-site disaster recovery (DR) environment, the PR configured to satisfy a recovery point objective (RPO) that specifies an amount of tolerable data loss applied to failover data of a first site to second and third sites of the DR environment, wherein the number of common snapshots is calculated based on pair-wide replication from the first site to the second and third sites;
compute a frequency of snapshot replication among the sites as a parameter of the PR so as to retain a latest common snapshot of the common snapshots for use as a recovery point; and
transmit replication of snapshots of the failover data from the first site to the second and third sites, respectively, to update the latest common snapshot.
