I'm sure it is. What does that have to do with backup in Linux?

Presuming your newly installed drive is /dev/hda, and your dup drive
is /dev/hdc; and presuming you have partitioned /dev/hdc the same as
/dev/hda; and presuming your mount points are / and /usr; and presuming
you have dump installed; you can:

# init 1
[ stuff happens ]
# mkdir /tmp/hdc1
# mount /dev/hdc1 /tmp/hdc1
# dump -0 -f - /dev/hda1 | (cd /tmp/hdc1; restore -x -f -)
# umount /dev/hdc1
# mkdir /tmp/hdc3
# mount /dev/hdc3 /tmp/hdc3
# dump -0 -f - /dev/hda3 | (cd /tmp/hdc3; restore -x -f -)
# umount /dev/hdc3
# exit (or halt and remove your dup drive, or whatever)

Install boot blocks on your dup drive and you're set.

If you just want an image file (ala Ghost, which you can almost emulate,
per partition, at least) by changing the dump command to:

# dump -0 -f - /dev/hda1 > /tmp/hdc1/hda1.img
# dump -0 -f - /dev/hda3 > /tmp/hdc3/hda3.img

and then copying the image files somewhere "safe".

You can also use tar and cpio and ...
