One of my new year chores is to sort through my old data on the computer and remove unneeded information. At the end of that process, I will, of course back up my data. Data back-ups need to be performed monthly at minimum. These days you can use software with an external hard drive to save all your information in the event of a crash. You can also purchase online storage services that will automatically back up everything on your hard drive on a regular basis and store the information for you. Now matter which way you decide to save you information, just make sure you do it!
