SyncBack is a flexible, and powerful backup and synchronization program that allows to maintain backup copies of your files and folders, or to synchronize them, so that both locations always have a complete copy (e.g Laptop/PC). It offers different types of actions that let you choose how older and newer files are processed, which files should be excluded (by mask) and more.
Features include standard file comparison based on the date and size, as well as optional MD5 checksum, which will detect even the slightest modifications to files.
