As others have said - rsync. The advantage is that it will 'sync' rather than blindly back up everything, even if it's already backed up.
Example: rsync -avx / /media/backup Everything in / is written to /media/backup, but it avoids mounted filesystems (-x says stay in 1 filesystem). Keeps you from backing up /media/backup :-) You can add the --delete option to the above to do a 'true' sync and erase files on /media/backup that are no longer in /. You can run the rsync over and over and only the new or changed files are written to the backup target. There are tools (rdiff comes to mind) built around rsync to provide various features and function related to backup. 'man rsync' gives some good examples of use up front. I use it on all my home systems to do backups, move filesystems around, etc. Excellent tool.
