[arch-general] Basic tar backup ?

[Allie Daneman]

So I just want to tar up the whole box (small server)...can I just do this:
tar -zcvpf /archive/full-backup-`date '+%d-%B-%Y'`.tar.gz \
    --directory / --exclude=mnt --exclude=proc --exclude=dev --exclude=sys .

Sorry if this a dumb question...I'm a Linux newb coming from BSD's ;)
