Abstract
Architecture for efficiently ensuring that data is stored to the desired destination datastore such as for replication processes. A copy of data (e.g., messages) sent to a datastore for storage is stored at an alternate location until a received signal indicates that the storage and replication was successful. As soon as the feedback signal is received, the copy is removed from the alternate location, and hence, improves input/output (I/O) and storage patterns. The feedback mechanism can also be used for monitoring the status of data transport associated with log shipping, for example, and taking the appropriate actions when storage (e.g., replication) is not being performed properly.
