Default backing up via 'dump'...

Greetings fellow daemons,
I'm trying to backup my system via an external USB drive via 'dump'. Basically I want to back up the / /var and /usr filesystems to similar partitions on the USB drive. I used fdisk and the disklabel editor to format and create 3 partitions on my USB drive. How can I use dump to mirror the partitions on my system. So far I have had no much success...dump doesn't seem recognize the filesystems created on my USB drive and when I try to back up my filesystems to files on the external drive it doesn't seem to be successful (backing up / and /var created two files the exact same size and far less than the actual size of either partitions)

Are there any good how-tos out there I may find useful...should I be using different backup tools?

Is 'dd' as effective as the man pages seem to suggest? Are there significant issues in backing up a live filesystem this way?

Thanks in advance,
Damien
