Claim 0:
1. A method comprising:
creating one or more protection rules (PR) to retain 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;
processing the PR at the first site to compute parameters including frequency of snapshot replication among the sites so as to retain a latest common snapshot of the common snapshots used as a recovery point; and
transmitting snapshot replication of the failover data from the first site to the second and third sites, respectively, to update the latest common snapshot.
