2.8 Coherency Requirements
The queue manager uses a local persistent store to persist its state and data in an implementation-specific protocol-independent manner. The Microsoft Message Queuing (MSMQ) protocol set does not mandate any specific redundancy strategy, inconsistency-detection mechanism, or backup-restore requirement for the implementation of the persistent store. If the storage system is unable to persist data due to exceeded capacity, the MSMQ protocol set fails the entire related operation and performs any necessary clean-up operation to restore coherency of the store.
