Abstract
An apparatus comprises an object store, back-end storage supporting the object store, and a file system associated with the back-end storage. Objects of the object store are mapped to files of the file system. The file system is configured to provide file system metadata extensions for respective ones of the files, with the file system metadata extension for a given one of the files comprising a plurality of sets of attributes characterizing respective ones of a plurality of accesses to the given file. The file system metadata extension for the given one of the files may be updated responsive to each of the plurality of accesses to that file to incorporate a corresponding one of the sets of attributes. Each of the sets of attributes may comprise, for example, at least one time-based attribute and at least one data integrity check attribute.
