"Live HD mirror software"

[philip_98]

I do a type of work that generates a very large volume of data every day and during the day. Twice so far I had HD crash during a work day, and had to pay a lot of money to date recovery companies. Is there a sofware that will enable me to have a mirror HD "live" while I work, so that if one crashes I can immediately swap the other one and continue to work?
Thank you for any comments.

What you need is a Raid setup.

Thank you bobw but I don' hink that this is the answer to my problem. In an array setup you loose one drive you loose all your project. What I am looking for is to use a second drive as a carbon copy "mirror" of my primary drive. I do have software that does that at the end of each day but that is not good enough. I need the process to take place "live" as I work.
Thank you for your reply anyway.

Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.

disk mirroring

A technique in which data is written to two duplicate disks simultaneously. This way if one of the disk drives fails, the system can instantly switch to the other disk without any loss of data or service. Disk mirroring is used commonly in on-line database systems where it's critical that the data be accessible at all times.
