If you use the packaged version of BackupPC please just use /var/lib/ 
backuppc for your backups. You can (bind) mount your backup space at  
that location. Alternatively create /var/lib/backuppc as a symlink to  
your backup storage. Also make sure that the filesystem you're using  
supports hardlinks.
