Computer stores are chock-full of all manner of backup software and network storage appliances of varying quality, usefulness, and ease of use. Do you really need some expensive commercial product? Probably not. Backing up Linux/UNIX systems is easy, and *nix comes with everything you need. Backing up Windows systems can get expensive, what with all those per-user and concurrent and per-machine blah blah licensing, and cross-platform backups can drive even strong admins to develop substance abuse habits. But don't run out and start one just yet, even though you'll be able to afford it, because this two-part series is going to show you how to perform the two primary types of backups the easy and cheap way: data files on a mixed LAN, and custom operating system images for fast bare-metal restores.
