Actually they are more concerned about data corruption and audits. The hardend offline facilities are about being able to compare known data to what's online or meet gov't requirements for audit background. Their rule for designing systems is that any one box can get nuked without bringing the whole thing down. This is why I've gotten into the habit of differentiating archival storage from backup systems. In most warehousing systems people mean "redundant" when they say "backup" (e.g., "a backup power system") and "archival" or "offline" for slow storage used to recover from data failures. Aside: most places have plenty of ways to deal with hardware failure. Unless they hire consultants, most never even think about how they'll handle data corruption. Hmmm... how about "You're not paranoid, the boxes ARE out to get you" as a slogan? -- Steven Lembark 2930 W.
