If the total storage capacity is 12TB and it's a video recording system, rsync over a 1000BaseT-to-1000BaseT cat5e patch cable between two systems could work fine. Rsync will only transfer the files that have changed. Set it up on a nightly cron job to run at 0200 in the morning, you might see less than half a TB transferred per day.
If the RAID arrays on both end can sustain 75 to 90MB/s sequential reads and writes a single GbE connection should be more than adequate for a middle of the night sync.
