JesCopy

This Windows program does all the synchronization, backup, and miscellaneous copy tasks you have over and over when mirroring hard disks or mobile devices, or on network sessions. It enables you to synchronize a folder and helps to come through with the Windows Explorer problem that it aborts a file transfer completely when a network error occurs. On the one hand, JesCopy is easy to handle, on the other hand, it can be very powerful. For example, it can update a folder from another one or in both directions, with or without subdirectories, file filters, attributes, and so on. But you can also create a copy of the directory structure only, show prompt dialogs ("please insert disk") and write script files that do backups. Of course it can execute external programs and branch on their success.
