Default backup with dd

hi all,

i have a centos box and would like to back up just in case the hard drive
fail. one way to do this is duplicate the image of the hard drive, so if
the hard drive fail, just remove it and put mirrored hard drive and done.

here my system info:

uname -a
Linux jadenet.jadesterling.com 2.6.9-22.0.2.EL #1 Tue Jan 17 06:51:40 CST
2006 i686 i686 i386 GNU/Linux

df -h
Filesystem Size Used Avail Use% Mounted on
37G 15G 20G 43% /
/dev/hda1 99M 8.9M 85M 10% /boot
none 188M 0 188M 0% /dev/shm

i'm looking into dd, but is there anything better than dd?

by the way, i would like to use external hard drive via usb to do mirror

this is an internal box and very little info/actvities going on in this
box. so, i don't have to worry about backup everyday. i may want to
backup once a month.
