We've had Back Blaze for our company for 3 months. As of now we still do not have a back-up. We have three machines that have critical data on them, one being our server. We purchased their three computer option. All BackBlaze has done is try to get us to sign up for the free trial or purchase their service. As we have purchased their service, we are just trying to get the systems to back-up. What complicated the process is that they have NO tech support.We will be going back to Crash Plan.
