I've read a couple of articles about bringing your
computer on the road or to sea that state, "make sure you backup you
computer and leave a copy at home". That might work for a day trip, or maybe
even a week, but it doesn't cut the mustard during extended travel. Don't
rely solely on CD/DVD backups. This media degrades; we are at the phase of our
journey now (four years) where some of our original backups are failing and
can't be read anymore. We're not sure if it is the scratches that inevitably
end up on the media overtime, exposure to the sea air, or the limited shelf
life of the media itself. They have a new class of DVDs called archival DVDs
that are supposed to last much longer than standard DVDs. If you do plan on
using CD/DVDs for backup, re-copy the critical ones every so often (yearly)
and make sure you invest in a good storage case. Keep the underside of the
DVD against the soft side and NOT against the CD/DVD jacket insert. We have
multiple friends who have lost their entire DVD and music collections due to
scratches caused by constant movement.
