    Are you wanting to completely copy the hard drive or just portions of it? Also, how often will you want to do this?

    If the backup drive is in the server a RAID 1 card will write everything written to the master disk to the slave(Backup) disk, Hope this helps.

    I would add that unless cost is a major issue, I would upgrade your setup to RAID 5 instead of 1 for reliablility. RAID 1 has generally fallen out of favor for techincal and lower cost of RAID 5 systems. Old Man already answered the how to issue.

    Yes, and the drives are hot swappable

    Depending on the interface, right? Or can you hot swap a Parallel IDE drive?

    RAID 1 or 5 is generaly SCSI not IDE but could be if you wanted it that way. Usually you don't see RAID drives of any type until you get to servers because thats where the redundancy is really needed. Same for multiple NIC's, power supplies, controllers, processors, etc....
