Best External HDD Software?

[zythyl]

What's the best software to use to simply sync one of my folders to the external HDD dynamically? As in live / constant / all the time (I save a file to the synced folder and it instantly does it to my HDD as well)?

SyncToy.

Download details: SyncToy v2.0

We use SyncToy at work. It's good stuff. The only thing is, you can't automate backups. But hey, all you gotta do is open the program and hit 1 button. It does the rest.
