Backing up data with rsync
- [Instructor] Whether your using Linux as a desktop machine or on a server it's important to back up your data. Data that needs to be backed up is generally data that's generated by the user, or by people using the system. Normally we don't really need to back up an operating system if we back up user data and configurations. Operating systems can be reinstalled, but holiday photos and customer data can't be as easily recreated. Before we start talking about backups, though, it's important to understand what a backup is. If you have a document file on your desktop and you make a copy of it and move it to your documents folder, that can seem like a kind of backup. There's two copies in case something happens to one of them. But if your hard drive crashes, chances are, you won't be able to access either copy. So that doesn't really help. A much more reliable approach is to copy files to another disk or system, ideally one that's usually detached from the system and stored somewhere…
