Automated Linux Server Backup Tips and Tricks
Here is a great way to backup a one-off server, including its MySQL database. To function best with hosted virtual machines, it is important to not store backup data. The script below compresses all data and ships it across the wire to a backup server in real time, implementing bandwidth throttles to avoid pummeling the remote server. This will work on any Linux server, especially a recent Debian install.

All good questions, and all handled fairly well with both rsync and tar using the right options, as we will see in a moment. Next is the issue of incremental backups. The great thing about centrally-managed backup software is that it generally handles incremental backups quite well. Scripting something yourself requires you do this manually, but not to worry, I've got a few tricks to show you...
