Abstract

An approach is provided that receives a file request and maintains a set of file versions of the requested file on a network-accessible storage media. The file versions are retrieved from the network accessible storage media along with expected hash values corresponding to each of the file versions. The retrieved file versions are stored in a second nonvolatile storage media, such as a local nonvolatile storage. File versions are selected from newest to oldest. When a file version is selected, a hash value is computed for the file and this hash value is compared to the expected hash value that corresponds to the selected file version. The first (newest) file version with a hash value that matches the expected hash value is selected and returned to the requestor.
