Claim 18:
19. An apparatus comprising:
a network connecting a first node of a first site to remote nodes of second and third sites of a multi-site disaster recovery (DR) environment, the first node having a processor configured to execute program instructions to:
create one or more protection rules (PR) for retaining a number of common snapshots across the nodes of the 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 the first site to the second and third sites, wherein the number of common snapshots is calculated based on pair-wise replication from the first site to the second and third site;
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.
