With Martian LifeBoat, you define sets of files and folders to be backed up (we call these "LifeBoats"). Each LifeBoat is associated with one removable media device — a particular USB Flash Key or external Hard Drive. Each time the associated device is connected to your Mac, Martian LifeBoat springs into action and starts backing up the specified files and folders onto the device. Now, your device contains a perfect mirror of your files.
