Typically, we exclude such application-specific trees from updatedb and 
other tree-traversal processes.  Another best practice is to put the 
pool on it's own filesystem/storage.

I didn't think open-source backup systems that pool storage even existed 
before I found BackupPC, so if you're concerned about storage pooling, 
you only have to worry about BackupPC.  Only commercial solutions do 
that (ie. Connected Dataprotector), and that is one of the reasons I 
installed BackupPC last week and am doing my best to commit to it, since 
it can result in a huge savings win if you're backing up more than 5 
machines with identical OSes/configurations.
