It's almost as if you guys haven't heard of filesystem-specific dump 
utilities.  For such utils (vxdump, ufsdump, zfs send/receive, etc.) the 
number of hardlinks isn't a problem.  You can do both full and 
incremental dumps, even across separate machines.  This isn't a problem 
that needs solving.

I feel like the whole "we need an SQL/hybrid" solution discussion is 
happening because you aren't aware of better ways to do things.  Just 
because a filesystem is a database doesn't mean it would be "better" to 
replace it with a "better" database.

For anyone thinking that working with giant multi-gigabyte BLOBs in a 
database is the right way to go, I suggest you actually attempt it 
yourself and see what happens.  I'm backing up my HD video production 
rig with BackupPC, and although such a machine (Windows, 16T of storage, 
most video files are at least 50G in size) is outside of the intent of 
BackupPC, it actually works.  If BackupPC were to rely on an SQL 
database, it would greatly shrink the potential userbase.
