I am looking for recommendations to clone a Red Hat mirrored raid to a single hard drive located in the same machine. The idea is if the servers hardware ever has an issue we have a similar hardware machine ready to go. All we would have to do is pop in the cloned drive. If the servers RAID ever failed we could just switch to the single drive to maintain uptime and restore the original configuration on the spare server with a backup.

This is a restaurant and they are open 7 days a week. We do have time from 12:am to 9:00am to perform the necessary steps for a clone and we talking about under 10 Gigs of information.

There is a database on the server.

I have looked into Rsync and Clonezilla. But I am just not confident either is capable of completing the task I want. Looking for some suggestions and possibly a step by step if you could be so kind.
