The recovery fragments needed to perform recovery of a chunk are determined, and assigned to the geographically distributed sites as subtasks. Each site that receives a subtask from the requesting site obtains XOR-related fragments needed to produce the recovery fragment, performs the XOR operations on the XOR-related fragments to produce the recovery fragment, and returns the recovery fragment to the requesting site. When finished, a site receives another subtask until no subtasks remain, such that the fastest site or sites receive the most subtasks. The requesting site recovers the chunk from the received recovery fragments. The shared participation in the chunk recovery among the distributed sites provides for efficient distribution of the recovery-related resources and work."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed site data recovery in a geographically distributed data storage environment","description":"The described technology is generally directed towards recovering a chunk (or similar block of data) when the chunk is erasure coded into fragments, and recovery fragments need to be obtained from geo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11513920","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
