Comparing User-Managed Rebuild and Duplexing Rebuild

Structure rebuild and duplexing rebuild provide the framework by which an application can ensure that there is a viable and accurate version of a structure being used by the application.

Structure rebuild allows you to reconstruct the data in a structure when necessary, for example, after a failure. Duplexing rebuild allows you to maintain the data in duplexed structures on an ongoing basis, so that in the event of a failure, the duplexed structure can be switched to easily. Duplexing rebuild is the solution for those applications that are unable or find it difficult to reconstruct their structure data after a failure occurs.
