If you want to be sure your data is 100% safe. I use backup internet software to get my backups done for me. You can get a couple of gigabytes of backup for free, if it's not enough room, upgrade to an unlimited package for a small monthly fee. An online photo backup is a great idea since this is something you really don't want to lose.
If you like to keep your folders the same on multiple computers, the solution for you may be the best PC backup software I could find. Whether the device is portable, a laptop, personal computer, the internet, or even a MAC, this software will do all it can do keep a designated folder the same on all of them.
TIP! Any time you are backing anything up, don't compress or archive, just do a straight file copy. If a part of the archive becomes damaged your backup is useless.
A good battery backup unit will not only shut down your computer properly for you, if the current to your computer is too high or low, it will also stabilize the power.
