But it works just as well as a back-up tool for your PC, and can potentially copy entire drives quickly and easily. SyncToy's original purpose was to synchronise data between your computer and your mobile devices, such as digital cameras and MP3 players. One of the key advantages of SyncToy is that it scans your folders for changes before copying the files, so if you've only added one photograph to your Photos folder recently, it won't attempt to copy the whole lot. It's powerful and versatile, and incredibly easy to set up and use. SyncToy is a free, official Microsoft add-on for Windows, and it enables the creation of duplicated folder pairs within your operating system. However, just because you can't take advantage of RAID in Windows Vista, the news isn't all bad: there are readily available alternatives to RAID. This is great if you have lots of important documents, a large music collection, or family photos and videos. Subsequently, if one disk fails, an exact duplicate is available to be used straight away on the other hard disk.

With this function enabled, data is written to two separate hard drives simultaneously, meaning that you have two copies of the same thing.
