We contracted with WTS and are in the process of coming up with a plan. I expect to get the draft version from them sometime this week. Having said that, the information of probably proprietary, but I can give you some general information once I get it. They host your site at their facilities and you access it via internet. After a certain amount of time, if your system isn't back up, you contract with them for a short term hosting solution. I can let you know more later.
Bottom line, you need to look at your own requirements to decide if you want to go with Mimix or tape restoration or somewhere in between. We are not a 24/7 shop...we're a public agency and can afford a little more down time than a manufacturing environment or other businesses.
