linuxhaxor.net— Now that you have the ultimate setup that you?ve worked so hard on, how are you going to be sure you have the same setup after a system or hard drive crash?

The best solution I have found for backups is using rsync with the "--link-dest" option. It allows you to keep multiple backups but doesn't waste space since it uses hard links for files that haven't changed. In the end this is similar to Apple's time machine. We use this where I work to backup a 600GB partition to an 1TB drive that is connected to another server. As the files are not changing very often, 1TB is enough to keep daily backups up to 7 days back. The cool thing is that you can mount the backup partition read-only over NFS, so users can just restore files themselves if they accidentally delete something.More details here: <a class="user" href="http://www.mikerubel.org/computers/rsync_snapshots/">http://www.mikerubel.org/computers/rsync_snapshots ...</a>
"Also, make sure that if you use this that the computer you restore it to is the same, or at the very least, exact same hardware, else it will crash the machine when you restore."Bollocks. This really only applies to Windows and custom kernels with missing drivers. X may have issues if xorg.conf specifies a driver for a different brand, but the system itself shouldn't crash.

Instead of manually excluding mounted partitions, there's also an option to restrict tar to one file system.
