Tape encryption has always disturbed me and DRBD works really well
I set up an unmanned DR center. It was a lot of work take your workload and multiply it by three, management doesn't get it, Documentation needs to be very, very good and kept up to date make sure the same tape drive are in the DR center that are in your production facility, I have always worried about encrypting tapes, KISS method. Take images of your servers and put the image where the server is not. I could take my data volumes and send the changed files on demand with DRBD to the DR site. It will use the bandwidth and trickle the change to the remote DR site as it can. If you add openvpn you can compress and encrypt also. DRDB (Distributed Replicated Block Device) is a huge savior for getting data across the links, THANK YOU Linbit!
