Abstract: There is provided a method of, and apparatus for, enabling data recovery on a data storage resource. The resource includes a file system having a file system structure component for data storage management. In use, a storage request operable to modify the file system is received, processed and the file system structure component updated based on the storage request. Subsequently, a data record recording the modification by the storage request is generated and used to update an auxiliary file system structure component separate from the file system structure component. By providing such a method, a file system structure can be recreated and recovered quickly after a failure or error utilising the auxiliary file system structure component. This enables a file system to be reconstructed much faster than conventional approaches because the auxiliary file system structure has already been created.
