Methods and multi-site systems to provide recovery point objective (rpo) protection, snapshot retention between secondary storage site and tertiary storage site, and automatically initiating 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:

• 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:
• initiate a snapshot create operation to create a snapshot copy of the one or more storage objects of the first storage node based on an asynchronous mirror policy from one or more storage objects of the first storage node to one or more replicated storage objects of the third storage node;
• and
• intercept the snapshot create operation on the primary storage site and synchronously replicating the snapshot create operation to transfer the snapshot copy to the second storage node to provide a common snapshot between the second storage node and the third storage node.
