even if all the "rsyncing" needed would be something equivalent to "mv holidays_2013 family_holidays_2013" on the remote server. Is it possible to tell rsync to behave in that way?
No, which is why some people use Mercurial or git to keep data in sync in multiple places. It's not very space efficient, but can be more network efficient than rsync in transferring changes and renames.
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.
