Another method:
If there's broadband service, 
1. tar|gzip the data dir, and scp it to a cheap, old box sitting 
   off site (say, with an internal 100GB HDD) that has firewire.
   160GB should easily store 14 days at 15GB perday, if the data 
   is even 33% compressible.
2. plug an external 160GB firewire disk into that box, and cp the
   tarball onto the external disk, and tote it to a 3rd site.
   You'll need a 2nd external 160GB firewire disk for rotation

Thus, if office goes up in flames on the same day the building 
where the off-site PC gets burglarized, there would still be a 3rd
copy out there.

Some former UNSCOM officials are alarmed, however. Terry Taylor,
a British senior UNSCOM inspector from 1993 to 1997, says the
figure of 95 percent disarmament is "complete nonsense because
inspectors never learned what 100 percent was. UNSCOM found a
great deal and destroyed a great deal, but we knew [Iraq's] work
was continuing while we were there, and I'm sure it continues,"
says Mr. Taylor, now head of the Washington
