Interesting. As posted before, replication could give you a copy which could be used for queries as well. If I may ask, why are you looking at NBackup versus a replication solution? Ease of use/setup? Or perhaps you intend to use nbackup to perform the backup and restore it to a different host? AFAIR you're dealing with huge amounts of data so I assume you don't?
