Some very newbie questions.

I have to move an old SCO-Unix server to a Cent OS 6.0 guest on a Cent 
OS 6.0 Host.
The space used on the SCO is 65 GB.

How shall i plan the storage ?
Make an image based guest of 100 GB an install on that ?
Or is LVM based better regarding performance ?
Should i allocate 100GB or 200 GB ? What is best ?

What about backup ? Should i take backup from the guest with tar/cpio or 
backup of the image file on the host ?

What is the preferable ?

Regards Thomas.
