Background: I have a Red Hat Enterprise 5 server in a production environment. It is a quad core 4gb machine w/ the OS on a hardware Raid 1 setup. It runs one software application managed via ssh from the software company located in Austria; they completely maintain this application. Each night we backup the directory specified via the software company. I am not confident that this backup is enough, this is an absolute mission critical application for the company. I check daily the hard-drives (visually ensure that the lights are not indicating hard drive failure) and that the backups run and transfer duplicate backups offsite each night. I am not fluent in Linux, and know only the basics, probably quite a bit less. What is the best method to make a complete backup or clone or virtual clone of this system? I am looking for a solution that could be restored "quickly" should a disaster occur. My concern with Ghost or Acronis is that as the server is 2 years old, finding the identical hardware may be a concern. My concern with a virtual system is that there is a Serial Modem attached to this system for faxed quotations on the sales side and have not had great luck with serial ports on VM's.
