You can either create a software or a hardware (recommended) managed Mirror. In case of a disk crash you still have a copy of the updated data on the disk. BTW, please make sure you hit "Reply all" instead of "Reply". this also keeps the freebsd-questions@ updated which will allow others to look into this mail and provide a better answer as well as help future users.
