+The file to synchronize can be any file where data is expected to change partially or completely between updates.
 Any local file that might contain data of the source file may be used as seed while cloning.
 
-In a software update system (IoT device/embedded system) with an A/B partition setup bita can be used to update the B partition while using the A partition as seed. The result written to the B parition will be an exact clone of the remote file but the only data fetched from remote is the data which actually differ between the A partition and the remote file.
