Drive mirroring - opinion wanted

[gaf-mNDKBlG2WHs at public.gmane.org (Jerry Feldman)]

recently, I acquired a 1TB SATA drive for home as an addition to my=20
existing 160GB drive. Obviously, the proper way to set things up are to=20
have 2 identical drives. I do back up my system daily to a USB drive,=20
but I would just like some recommendations before I move to Fedora 11.
I do have enough space on a USB drive to back up everything important=20
(such as /home, and my virtual machines) so I can do a complete reformat =

if necessary.
But, what I would like to do is to continue to use my 160GB as my=20
primary drive (currently set up as LVM), and install fedora 11 onto the=20
new drive. I currently have 1 137G volume group on the 160 GB drive. Can =

I simply allocate a 137GB volume group on the 1TB drive to use as a=20
mirror for the 137VG on the 160.

Or, would I be better off starting from scratch when I install Fedora=20
11, use the 1TB drive as the boot drive and set up multiple volume=20
groups, or simply just rely on my existing daily backups.
