Abstract
The authors introduce two enhancements to optimistic recovery
which allow messages to be logged without performing any I/O to stable
storage. The first permits messages to be instantaneously logged in
volatile storage, as in the sender-based message logging technique of
D.B. Johnson and W. Zwaenepoel (1987), but without their restriction of
single-fault-tolerance. The second permits message data and/or message
arrival orders not to be logged in circumstances where this information
can be reconstructed in other ways. They show that the combination of
these two optimizations yields a transparent n-fault-tolerant
system which logs to stable storage only those messages received from
the outside world and a very small number of additional messages
