Image for Windows
Update: May 2014: Image for Windows has never failed me. I recently found my main hard drive on my Windows 8 machine failing and installed a new drive, booted up the image for Linux CD, restored from backup and I was instantly up and running. Also did this for a client on a new machine with Windows 7. Thanks Terabyte.
Best backup EVER!!!! This is a fantastic backup product that works really well. I have tested it in a bunch of different places and it always gives perfect results. It is a bare-metal backup solution that can be used for any version of windows even windows 7 and server 2003. It makes a backup file (tib) that can be browsed and even mounted so you can restore individual files or the whole operating system. There is a version for linux that has a boot disk and it will backup your linux partitions. The best part is it will do a complete restore. I use it for my computers and set it up for all of my IT clients. It can backup all system, hidden and even in-use files. You can run it in the background while you are using the computer (although I wouldn't recommend it)
You can download a trial version if you want to test it out but this software is so cheap you should probably just buy it. I am so happy I found this software. I have used other products that cost hundreds of dollars but nothing works like Image for Windows and costs less than $40 a copy. In my quest to find good backup software I have struggled with other programs making endless backups only to get thwarted when I try to restore from them and they fail. This one works every time. I love it. This is the best backup software I have ever used.
