nxtKeepSync is a handy application that was especially created to help you save important data and have it synchronized so the latest changes will always be backed up.

The program is able to mirror the information from the source folder into the target directory. Please note that if this mode is selected, the old data will be deleted from the target each time a synchronization occurs.

Another method you can use with nxtKeepSync is the simple 'Copy', which will keep the files intact when syncing.
