Yep!, That would be a good idea to exclude those if you were backing up /, however I was talking about backing up a non running system mounted at /mirrordisk. If you want to backup the root filesystem (that is, the root filesystem that is currently in use...) You absolutely would want to exclude the /proc, /backup, and mounted partitions that are not part of the system you wish to backup. Most of my systems have other OS's (such as SuSE, SlackWare, Mandrake, and even windows), so i would exclude those aswell.) In practical application, I rarely backup my systems, I re-do them rather often, and usually keep working systems, and re-do one system at time(this way I have other systems on the disk to look to for config files and such...) When I backup, I usually just backup /data, and /home/<user>, and sometimes /etc (for config info...).
