Yes, and that's why a database would be more efficient than hard
links...
I've just read that Diligent ProtecTIER can store all the links for a
1 PB pool (yes ! peta bytes !), in just 4GB of memory. With the links in 
memory, they can
achieve very high backup speeds and doing on the fly deduplication.

Maybe the way to go for BackupPC ?
