In some cases, file fetching and restoration may be performed by a storage appliance using master file references in which a master file is identified for each multi-link file that is backed-up on the storage appliance and then referenced by one or more hard links to the multi-link file. In other cases, file fetching and restoration may be performed by a storage appliance using index node-based mappings for multi-link files that provide mappings between index node identifiers (e.g., inode numbers) for the multi-link files on a primary system and hard link paths for storing the file contents of the multi-link files on a storage appliance used for backing up the primary system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backup and restore of files with multiple hard links","description":"Methods and systems for backing up and restoring files that have multiple hard links using master file references and index node-based mappings are described.
