I haven't tried on this machine, but with an earlier 250 gig setup I was 
never able to complete a copy over a weekend with any of the 
file-oriented approaches.  Dump can dump the inode numbers but restore 
will remap them to different numbers, needing a lookup table for all 
files with multiple hard links - which with backuppc is all of them.
