Is it just data you want to copy, rather than an restore image?
RAID would be one way to go, another is create a data backup area and
use cron to copy files over. Just guessing here I would be very
surprised if there wasn't a utility available that monitors directories
for changed files and can copy them.
There are also several Linux backup applications.
Did you get as far as installing the disk, creating the filesystem?

copy or gzip/bzip2 your data over to the 2nd drive. You can make use of one
of the many open source backup programs or scripts.
boot even in case of one drive failing (if you use the "raid-extra-boot" in
lilo or comparable settings in grub) or at least can be easily reactivated
from the remaining drive. However, you should not run the 2nd drive on the
slave, rather use 2nd master to avoid speed loss. And consider, raid1 does
not substitute a good backup - because accidently deleting stuff does it
instantly and simultanously on both drives.
I am using a raid1/raid0 (software, configurable per partition) setup with
two ide drives here for more than one year, and it already survived a dying
harddrive.
