Yes and no, Have 1TB daily changes to our production database which is approx 45-50TB is size. Been doing snapshots to a live disk storage library which mimics tape but is hundreds of times faster to restore, using a Quantum disk based system. Currently on a Dxi5500, because that Database isn't the only thing being backed up by that system.
The Quantum disk based backup systems can restore up to 10TB per hour without compression on some of the higher priced models. Not sure if its in/out of your price range as I wasn't involved in the purchase just the planning.
