In this section, we will look at using Time Machine to back up a server and the clients that use the server (e.g., to grab those iTunes and iPhoto libraries that are stored locally on each computer).

For example, you will want to have a copy of your data on tape, which Time Machine doesn’t work with. Or you may look to perform cloud-based backups, which Time Machine isn’t engineered for. But for most companies, Time Machine will work perfectly well to back up the operating system itself.
