Having a home server can be very useful when having a lot of computers at home or having a lot of machines with different capabilities. User can then choose which computer they want to use and will always have their home directory, group folders and shares right at the dock. Very convenient. But then you start to think about redundancy and data safety. What happens if your single home server crashes. All files and a lot of work will be lost. So there is a need for backups and since we’re using Mac OS X Server I started to look at Time Machine for backing up home directories.
