Well, computer viruses are awful, malicious hackers are lousy, power surges? Put money into an online backup software to make the procedure simpler. With this added complexity comes the increased likelihood of an issue.
Your computer likely cost you hundreds - maybe even thousands of dollars. That's one thing that you're sure to worry about if anything happens to the computer itself. However, there's another cost that is far higher than a few hundred dollars - the data that is on the computer.
Both the technique mentioned above is helpful and depends largely on the needs of yours. If you are ready to invest and a bit serious about your important data then go for having a local dedicated data center so as to have the data stored locally. This way you can have an extra control of each and every data bits which will be stored on the backup drive.
First, make a backup. Sorry, folks--there's no way to guarantee that your data will be safe without doing a backup. We're going to be partitioning your main hard drive here, and that means that data problems are possible. The first step is to back up all of your important files to external hard drive, CD, or through an data backup companies service. Double check to make sure that all of your data is backed up before heading to the next step. That way, you won't have to hold your breath while Windows 7 installs (which is a good thing, as it takes an hour or two and unless your Houdini you'll be pretty dead by the time the mouse drivers start loading).
If you decide to back up your important data, you need to decide where you want to backup. Would you like to back up data onto an external drive or want to use a different drive on your computer to perform the same task? The best option is to use an external hard drive to perform this task. If the amount of data is less then you can also consider DVD or flash drives.
The typical life span for a hard drive is 3 to 5 years. And the
