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 including a primary storage site having a first storage node, a secondary storage site having a second storage node, and a tertiary storage site having a third storage node comprising:

• a processing resource;
• and
• a non-transitory computer-readable medium coupled to the processing resource, having stored therein instructions, which when executed by the processing resource cause the processing resource to:
• provide a synchronous replication relationship from one or more storage objects of the first storage node to one or more replicated storage objects of the second storage node;
• provide an asynchronous replication relationship with an asynchronous update schedule from the one or more storage objects of the first storage node to one or more replicated storage objects of the third storage node to provide a protection configuration;
• track, with the third storage node of the tertiary site, a state of the secondary storage site;
• automatically perform a failover from the primary storage site to the secondary storage site and activating a synchronous mirror copy for the one or more replicated storage objects of the second storage node based upon detecting the failure event for the primary storage site;
• and
• automatically initiate realignment and reconfiguration of the protection configuration to the tertiary storage site based upon the state of the secondary storage site.
