You can go as far as making a new file system on one of the drives and 
copying over everything except the contents of cpool and the backups 
under the pc directories.  Or, if backuppc_Nightly is working now you 
might not need to start over.

My current system is using one of these with 750 gig drives:
http://www.startech.com/Product/ItemDetail.aspx?productid=HSB320SATBK&c=US
and I use mdadm to fail/remove/add the disks that rotate, momentarily 
stopping backuppc and unmounting to get a clean filesystem.

On a smaller system I might consider the laptop-form external USB drives 
that you can get in sizes to 250 gigs now and just unmount and dd the 
internal partition to it.
