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.
