When a hard drive crashes, precious files are often lost forever. But the computer experts at Keynetik LLC often can help reclaim them—or at least, they can launch a preemptive strike against crashes. Let them back up data online, and they'll not only have a copy in case of crash, but also mail you a DVD with your backed-up files every few months. This makes another of their services, hard-drive recovery, obsolete. The computer whizzes also will troubleshoot computer issues at your home or business, create custom websites, and teach you insider tricks at computer classes.
