I could tell you 10 different ways on how you can loose data, however I am sure everyone has experienced one or two of them. Your hard drive can crash, there may be a power surge, or someone could simply spill a drink on the computer. This is why backup is so important!

Often when I go to restore my computer or transfer my data to another system, I have more than likely forgotten to backup at least one important file. Sometimes it is a password or a setting, and sometimes an entire folder. By making simple mistakes, I have lost a lot of important information over the years.

However now I have vowed to religiously backup my data at least once a week. This is easy enough to perform as long as I can remember all of the files and folders I need to backup. My memory isn't that good
so I devised a list of the most important files to backup from my computer system.
