Well, there's your problem.

Just out of curiosity, why hadn't you already done that?!?

Interesting. I'd make sure that the filesystem is OK before I went much
farther... Stop BackupPC, unmount /backup and fsck /dev/<whatever>

With that, you should be able to find the bakup number(s) that are not
linked. You can delete them and free up space.
The big question is, though, why they aren't linking. I'd really start at
the bottom of the stack (the physical drives) and work your way up. Check
dmesg for any hardware errors. fsck the filesystem. Did I read correctly
that this is connected vis NFSv4? I sure hope not... (I'm willing to
admit it's a phobia, but there's no *WAY* I would trust my backup to work
across NFS...)
