Abstract: A data archival system for the automated archiving of data files. The data archival system includes a central processing hub for receiving the data files, a data archival facility connected to the central processing hub; and an archival manager which is configured to cause the transmission of the data files from the central processing hub to the data archival facility in response to an archive request; the archival of the data files transmitted to the data archival facility in response to an archive request; the retrieval of the data files previously archived in response to a retrieval request; and the transmission of the retrieved data files from the data archival facility to the central processing hub.

Abstract: One or more random access-type storage devices comprise a volume group and a journal volume. The volume group contains a volume pair configured from a primary volume and a secondary volume. Whenever data is received from a host device, this received data is written in the primary volume, a journal containing the write sequence of the data and the data is produced, and the journal is written in a journal volume. A plurality of journals accumulated in a journal volume are written in a sequential access-type storage device. Based on the write sequence recorded in each of the plurality of journals recorded in the sequential access-type storage device, the data of the journals is restored to the primary volume for storing the data and to a secondary volume from which the volume pair is configured.

Abstract: A method for archiving and analyzing manufacturing execution data using a server coupled to a database, wherein the data includes database tables, database views, and/or database scripts. The method includes selecting at least one data source having the data stored in a database, extracting at least a selected portion of the data from the data source into the database without further input; automatically formatting the extracted data according to a predefined format; and analyzing the formatted data according to a predefined report structure.
