You need NATS - Network Attached Tape Storage. Basically the high-end libraries will hook straight into your SAN. If you're prepared to buy used equipment, it isn't really that expensive these days.

When I worked at CML in Australia they were replicating the entire head-office SAN (which serviced about 2500 people) every day to a DRP site using a dual circuit 644MBps MAN.
