First, if you’ve followed my suggestions up to this point, you now have a large second hard drive installed on your computer. Invest a portion of this second hard drive in protecting your files. You know that the best media today to backup our large hard drives is not tape or cartridge systems, but is a second large hard drive. Hard drives are much faster than tape or cartridges, they cost much less than buying many cartridges, and they can be automatically setup to backup with little intervention. Using a hard drive to backup another is so easy that you will tend to do it more frequently than using other methods of backup.
	So, you notice that on my example I’m showing a backup partition that I’ve setup on each hard drive. This is a large partition (maybe 20 GB), but since only a few large backup images will be stored on it, you will not waste much space and you can save your backup files a bit faster with large cluster sizes.
	There are two types of backup operations that we need to do using these backup partitions. Let’s look at both of them.
