In a message replication environment, instances of a message volume are hosted by message systems. Each message system exchanges condition information with the other message systems indicative of the health of the volume instance hosted by the message system. Each message system then determines independently from the other message systems whether or not the message volume is sufficiently protected. In the event that the message volume is insufficiently protected, a protection action can be initiated.

Enhanced data protection for message volumes

Techniques to leverage replication to provide rolling point in time backup are described. Some embodiments are directed to techniques to provide rolling point in time backup with simplified restoration through distributed transactional re-creation. In one embodiment, for example, a technique may comprise creating a plurality of availability copies of a primary set of data; designating at least one of the plurality of availability copies as a backup copy; creating a log file that indicates changes to the primary set of data; updating the plurality of availability copies from the log file in near real time, without updating the backup copy; and restoring at least one of: the primary set of data and an availability copy using the backup copy and content resubmitted from a content contributor when an error occurs in at least one of: the primary set of data and an availability copy. Other embodiments are described and claimed.
