You probably want one symlink at /var/lib/backuppc pointing to the 
corresponding place on the data drive.  Or if this is going to be the 
new archive filesystem you could delete the other top level stuff, mv 
the directories under the old /var/lib/backuppc location up to the root 
of the filesystem, then mount it at /var/lib/backuppc.

The httpd config should be the only thing that doesn't like symlinks - 
make sure the 'Options' directive covering the relevant 
location/directory includes symlinks.
