This technology allows protecting data against failures of storage devices by periodically reading data object replicas and data object hashes stored in a plurality of storage devices and rewriting those data object replicas that have errors. The present disclosure addresses aspects of writing data object replicas and hashes, checking validity of data object replicas, and performing data scrubbing based upon results of the checking."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data scrubbing in cluster-based storage systems","description":"Disclosed is the technology for data scrubbing in a cluster-based storage system.
