In my business I provide IT support for residential and very small business customers. I don't handle any clients who are big enough to require a real Windows server like Windows Server 2003 or 2008. However, I have installed a couple of Windows Home Server appliances for customers - mainly for backup purposes. I love the backup feature of Windows Home Server. It's the closest thing I've found to Time Machine on Windows. The problem is that Windows Home Server looks like a dead-end. HP (who had the best boxes) is getting out of the business. The new version of WHS doesn't look that great. So, I recalled that Server will be included in Lion. A few questions: - is there or will there be a limit on the number of client PCs that can connect - can anyone recommend a free or near-free backup program for Windows that will work as well as WHS's? (automatic daily backups that are both file and image backups, and work with most recent flavors of Windows XP Home, Vista Home Premium or 7 Home Premium) - anything else I should consider?
