Hello, I need some software to backup my computers in the factory. These computers are mounted on some assembly lines, so if some computer fails and needed to be re-setup and re-configured, the assembly line stops for several hours. So, I need to created harddisk images of all computers on an external drive. So when some PC fails(i.e. harddisk or some software or OS), I can quickly boot to some bootable cd and restore the image to the harddisk. Or even if I need to install a new harddisk, i can get that image insatlled on the new harddisk and the PC would be functional in perhaps less than an hour. What softwares are available? I wont need incremental backups, just one time backup of the entire system. The softwares not necessary to be free. Just the process to be simple so that I will have minimum downtime on assembly line.
