would an external usb save information on my computer during a lightning strike
My office has 3 desktop computers, 1 is the main server, the other 2 are used by myself and my boss. Two weeks ago lines were struck by lightning. The computer my boss uses was affected it took out her motherboard. The main server is protected by an external usb. All the computer had surge protectors and battery pack backups connected too.
What should I buy for my computer in case another act of nature should happen?
