The map may be an SDDF map that indicates tracks of data that were modified. The external storage may be a cloud storage. Each of the entries may be created prior to deleting data for a corresponding snapshot on the storage system. The entries may be transferred directly from the storage system to the external storage. Extending snapshot retention for a storage system may also include periodically writing a full version of data from the storage device to the external storage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Extending snapshot retention","description":"Extending snapshot retention for a storage system includes creating a plurality of entries, each of the entries corresponding to snapshot data on the storage system and containing data that was writte","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11288131","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.
