Okay, that's your main design goal in your backup strategy; fast recovery in case of main disk failure.

Yep. > HELP.... > How do I do this. Pretty simple; duplicate the first disk on the second in some periodic cron job. Not too often, because if failure occurs during the copy, you'll be toast. > (Disregarding the disaster recovery for the momnet if > necessary) DON'T disregard the disaster recovery procedure. If you have't tested the recovery procedure, then you don't have a working backup system. Other things to note are the fact that if the whole system fails, is stolen, hit by lightning, burned, or so on, your system has no provisions for recovery. Make sure you have another (albeit slower) recovery procedure as well, preferably with off-site backups.
