Mirror is an easy to use freeware tool that duplicates a folder structure to a new location. Mirror is portable, requires no formal installation, and is multi-threaded so it has little to no impact on system resources. Only files and folders that have been added/modified are copied, so disk writes are held to a minimum with the result being a much faster backup compared to traditional methods.

Quick and handy, Mirror works with any hard drive or removable media that your operating system supports.
