Thin client system

It is one of the most terrible experiences that our PC breaks down. It is not only the matter of the hardware itself; losing the important data and software stored in the PC is occasionally way more severe. To tell the truth, I have a tough experience in which I had to close my small business owing to my PC crash. Making a periodical backup is indispensable and effective, but it is not enough. Actually in my past case, I had a backup file which didn't work because it was specialized only to a particular type of PC and I couldn't get the same type of PC in place of my crashed one at that time. It was really a lesson to me and I've changed my way to design and create a system since then. Important system should be run on the server and should not depend on any special environment on the client. My Windows PC broke down this afternoon, but my service is still running with no problem. Only the problem is that I have no Windows PC client now and I have to spend unexpected money for it.
