METHOD AND SYSTEM FOR PROVIDING DIRECT ACCESS RECOVERY USING SEEKABLE TAPE DEVICE

摘要

A method for backing up data in a computer system from a plurality of primary data sources to a secondary data source is provided. The method comprises copying data sections from the plurality of primary data sources to the secondary data source and providing a data pointer on the secondary data source. The data pointer indicates a starting point of each transfer from the plurality of primary data sources and where that starting point is on the secondary data source. This data pointer information provides the minimum information necessary to map a location from the primary data source(s) to its location on the secondary data source.
