SmartSync Pro is a backup and synchronization utility that will store your important files to a different drive, removable ZIP/JAZZ drive, network volume or just compress to zip archive.
Flexible filters system and built-in scheduler lets you synchronize only the files that are necessary and only when needed. To minimize data transfer (and increase speed) only new and changed files are transferred.
