Methods and multi-site systems to provide recovery point objective (rpo) protection and automatically initiate realignment and reconfiguration of a protection configuration from the secondary storage site to the tertiary storage site upon primary storage site failure

A multi-site distributed storage system comprising:

• one or more processing resources;
• and
• a non-transitory computer-readable medium coupled to the one or more processing resources, having stored therein instructions, which when executed by the one or more processing resources cause the one or more processing resources to:
• provide a synchronous replication relationship from one or more storage objects of a first storage node of a primary storage site to one or more replicated storage objects of a second storage node of a secondary storage site;
• provide an asynchronous replication relationship from the one or more storage objects of the first storage node to one or more replicated storage objects of a third storage node of a tertiary storage site to provide a protection configuration;
• automatically perform a failover from the primary storage site to the secondary storage site based upon detecting a failure event;
• initiate a communication from the tertiary storage site to the secondary storage site based on detecting that the primary storage site is temporarily unreachable.

A non-transitory computer-readable storage medium embodying a set of instructions, which when executed by one or more processing resources of a multi-site distributed storage system cause the one or more processing resources to:

• provide a synchronous replication relationship from one or more storage objects of a first storage node of a primary storage site to one or more replicated storage objects of a second storage node of a secondary storage site;
• provide an asynchronous replication relationship from the one or more storage objects of the first storage node to one or more replicated storage objects of a third storage node of a tertiary storage site to provide a protection configuration;
• automatically perform a failover from the primary storage site to the secondary storage site based upon detecting a failure event;
• and
• initiate a communication from the tertiary storage site to the secondary storage site based on detecting that the primary storage site is temporarily unreachable.
