[ale] backup suggestions

[James Kinney]

An alternative is to make one hard drive duplicate using dd, put it in a
remote machine elsewhere and use rsync over the net to keep it a current
duplicate. This is uselessly slow if the daily data change is measured in
gigs. But if the daily amount is even 100 megs, a reasonable connection
(hi-speed preferable) will suffice.
