<p><P>PROBLEM TO BE SOLVED: To preserve data to prevent loss of transactions and alienation of customers. <P>SOLUTION: A storage system comprises a controller capable of coupling a storage device, a buffer and a jounaling device and a process executable on the controller. The executable process comprises; a resolve utility capable of determining logical unit, track, and sector identification for a selected file on the storage device; a user interface enabling a user to select tracks and sectors on the storage device for restoration to a predetermined point of time or write sequence; and a restoration utility. The restoration utility accesses data corresponding to the selected tracks and sectors directly in the case of the latest write operation or through a buffer in the other case, from the journaling device to restore the data. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
