Abstract
A method for backup across redundant removable media includes the steps of selecting a current portion of a database to add to a backup collection. The backup collection includes N units of the removable media. N is an integer greater than two. Generating a backup file of a current file in the database using a K-of-N coding process. K is an integer less than N. The backup file has N parts. The current file may be recovered from any K parts among the N parts. Determining if less than N−K+1 backups of the current file exist in the backup collection. Writing a subset of the current file to a current unit of the N units in response to the backup collection having less than the N−K+1 backups. Writing a current part among the N parts of the backup file to the current unit.
