If a broadband internet connection is available, yes. That doesn't
apply to all sites.

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.

ack. I'd dispense with backing up /usr iff dpkg could re-install all
packages that are known to be installed from /usr/state with a single
call.
btw, if you do it this way, /usr/local has to be considered data, too.
