We frequently have clients who come to us after their computers break or are infected with a virus. Usually we are able to recover the computer files. But sometimes we can’t and all is lost if they don’t have backups. It’s a heartbreaking but frequent occurrence. And of course, some people lose their files due to theft or natural disaster.
That’s why we recommend offsite backups in addition to a local backup. There are many good services, but we use Crashplan which is free for a year for today at: https://www.crashplan.com/carboniteswitcher/
