Well, you can take a complete backup of the system simply by removing one of each pair of the RAID 1 drives if the root fs is also RAID 1. Given how cheap hard drives have gotten and how expensive high capacity backup systems are nowadays, removing one half of a RAID 1 array and replacing it with new drives is a really fast, cost-effective backup method. You can often buy a hard drive for not much more than a high-capacity (> 20GB) tape cartridge. And you can buy 50-100 drives for the price of a high-capacity automated tape drive. Several small engineering companies I know use this method. It generally is superior to tape backups until the company can actually afford an automated tape handling system. -a To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
