Abstract: A replication progress tracking technique is configured to present progress tracking state relating to data replicated as a recovery point (RP) from a source site to one or more target and/or remote sites over a network in a multi-site data replication environment. The progress tracking state of the replicated RP, i.e., RP replication progress, is persistently stored as a progress tracking recording at the target site independent of the source site of the replication and presented (i.e., viewed) using a well-defined, published application programming interface that is publicly callable by one or more clients of the environment.

Abstract: A technique provides network efficient data failover by explicitly protecting one or more common snapshot references at sites of a multi-site data replication environment to improve granularity of control of recovery point objectives (RPO) for data across the sites. A common snapshot reference or recovery point (RP) ensures that, in the event of failure to a site, data designated for failover may be quickly protected by replicating only small incremental changes to the RP so as to maintain RPO requirements across the sites. Illustratively, the technique enhances and extends a disaster recovery (DR) application programming interface (API) protocol through an extension that defines and applies a tag to the RP, wherein the tag enables protection and/or preservation of the RP by ensuring that the sites honor the tag applied to the RP. The tag essentially functions as an advisory lock for the RP that is shared among the sites to prevent deletion of the RP at the sites throughout the duration of the lock.
