Mime: a high-functionality shadow writing disk system - Slides presented at BASS-29

Jacobson, David M.

HPL-CSP-92-14

Abstract: Mime is a disk system using shadow writing to both improve performance and enable new features. One such feature is "rollback groups." Rollback groups provide a means to specify points at which a transaction is consistent. After a failure, the state will be restored to the last such point. In addition, roll back groups can be either committed or aborted, and thus provide support for the transactions.
