Ask any computer expert, and she will stress the need for not only local backups, but offsite backups as well. One option to get offsite backups is to use an online service. For many years, I was a happy subscriber to Carbonite. As the number of computers in my household grew, however, I needed a more economical solution. My wife and I each had a desktop and laptop, and I also ran a Windows virtual machine on one of my Macs. That made five systems that I needed to backup. After a bit of research, I settled on CrashPlan, and haven’t looked back. Not only is the CrashPlan+ Family Unlimited plan a good choice for a family with many computers, but CrashPlan might also be a good choice for you if you don’t want to pay anything at all.
