Abstract
The data from a plurality of primary data sources, such as disk drives or disk arrays, are interleaved and captured in a secondary data source, such as a tape drive, during a backup operation. The interleaving of data allows the overlap of read/write operations performed by the plurality of primary data sources, thereby optimizing the performance of the backup as well as the restore.
