  "country": "US",
  "title": "How to Keep Data Safe During a Site Failover",
  "original_title": "Method and system for star replication using multiple replication technologies",
  "summary": "A method for keeping data backups synchronized and accessible even when a primary data center goes offline and systems must switch to a backup location.",
  "what_it_does": "This patent describes a way to manage data recovery when a primary production site fails. It uses a star-like topology where data is replicated to a secondary site and backed up to a separate storage location. When a failover occurs, the system reverses the flow of data, treating the replication site as the new production site. It uses a delta marker stream to track differences between storage locations, ensuring that the backup site remains consistent with the new production state even during complex recovery operations.",
  "what_it_does_not_cover": [
    "Does not cover simple data mirroring without a failover mechanism.",
    "Does not cover data backup methods that lack a delta marker stream for tracking changes.",
    "Does not cover cloud-native object storage replication that does not involve a site-based failover.",
    "Does not cover hardware-agnostic data recovery that ignores the state of the production site storage."

  "abstract": "Example embodiments of the present invention relate to a method, a system, and a computer program product for performing data replication and backup. The method comprises performing a first data replication of a production site storage to a replication site storage and performing a first backup of the production site storage to a production site backup storage. A second data replication then may be performed from the production site backup storage to a backup site backup storage.",
