Abstract
Systems, methods, and computer readable media for improving synchronization performance after partially completed writes are disclosed. According to one aspect, a method for improving synchronization performance after partially completed writes includes receiving, from a requesting entity, data to be written to storage. The data to be written is sent to each of a plurality of data storage entities, including a primary data storage entity and at least one secondary data storage entity for providing a duplicate of the primary data storage entity. For each of the plurality of data storage entities, the portion of the data that was stored to the respective data storage entity is determined. For each of the secondary data storage entities, the portions of the secondary data storage entity that do not contain a duplicate of the corresponding portion of the primary data storage entity are identified as requiring synchronization, while the portions of secondary data storage entity that contain a duplicate of the corresponding portion of the primary data storage entity are identified as not requiring synchronization.
