I have found the sorcerer's stone and it is FreeFileSync.

carlcobb reviewed FreeFileSync:

Fast and easy to use. Allows me to sync selected directories between laptop and desktop quickly and accurately. Options include sync, two-way update, and clone. Works with Win 8.1, 7, and XP.

The most powerful file synchronization tools I have ever seen. Use it everyday!!

cadbloke reviewed FreeFileSync:

Awesome. Much more versatile than SyncToy. I love the fine-grained control and also the option to preserve deletions. I use it on a couple of identical external HDDs for off-site backups. Different drive letters? No problem, just copy the XML config file and change the drive letter. Save. Run. Done.
