Omit the "-z". It compresses traffic over networks but it
doesn't help with local copies.

You probably don't want to ever restore /dev, so backing it up
could be regarded as a waste of time. However it's small and
the information from a /dev backup is sometimes useful in
emergencies so go ahead and back it up.

/sys is a special filesystem like /proc. I wouldn't back it up.

Most people don't backup /tmp, /var/tmp, ... to save time and space.

Here's a one-liner. You might want to adjust the exclusions
to suit your needs. Make sure the correct disk is mounted on
/media/disk before starting. [With rsync v3 you can add "-X" :-) ]
rsync -va -SHA --partial --delete --delete-excluded --exclude=/media --exclude=/proc --exclude=/sys --exclude=/tmp --exclude=/var/spool/squid --exclude=/var/tmp --exclude=/mnt --exclude='/home/*/.mozilla/firefox/*/Cache' / /media/disk/
