I think an incremental 'dump' can catch renames.   zfs's incremental
send/receive would track just the changed disk blocks.  Not sure what
else would handle it better.   Backuppc would transfer a new copy but
if you were keeping more than one backup the matching files would end
up being stored as links to each other and not take additional space.
