NearSync replication<\/strong> has recovery schedules with an RPO between 1\u201315 minutes. Called NearSync schedules, they are also practically asynchronous schedules with 15\u2013minute or lower RPOs. You can configure the schedules for even 1 minute.<\/p> Some of the advantages of NearSync replication are as follows.<\/p> To implement the NearSync replication schedules, Nutanix introduces a technology called lightweight snapshots (LWS) to generate snapshots that continuously replicate incoming data generated by workloads running on the active cluster. The LWS snapshots are generated at the metadata level only. These snapshots are stored in the LWS store, which is allocated on the SSD tier. The LWS store is automatically allocated when you configure NearSync replication schedule for a protection domain.<\/p>
