Syncplicity - Syncplicity: Effortless Backup, Synchronization, and Sharing
Excellent sync service! Fast, easy to understand and use. I wish they would offer a little more free space (they do offer a 2 gb free account). Luckily I have a free 8 gb account, more than enough for my needs. I used iDrive up till now, it's dependable but I have difficulties understanding exactly the logic behind their approach... Go syncplicity!
