The DDS-3 tape drive we use can backup and verify about 2 Gig per
hour. That compares to the throughput of roughly 4.5 Mbps. Since in
Germany you can either have 2 Mbps or 34 Mbps (the latter costing
about 5 KEuro per Month in line cost without even having it connected
to an ISP). Thus, your approach is rarely applicable over here.
