Mirroring

This question has been featured in the FAQ since forever, but people keep asking the same thing over and over again: "I want to make a backup of a directory. I delete some file on the original directory, but the program doesn't delete it from the destination".

Well, let me tell you: A BACKUP PROGRAM IS NOT A MIRRORING PROGRAM. And this is a very dangerous feature to add for a backup program. A backup is a ONE WAY copy. If you delete a file as a mistake or if a virus destroys your data, you will EXPECT to find your files in the destination. If you implement a mirror, you'll find NOTHING there!

Anyway, if you want to take the risk, you can make a mirror by checking the Mirror option in the advanced properties of the task.
