SkyeFire - Thanks very much for the comprehensive reply which is a huge help, I've been asked to help back up some Kuka robot PC's as I'm an IT guy but I'm not at all familiar with them. The team responsible for the robots have been taking archives using the option the HMI but to be more complete, also want full backup images restored to spare drives which makes sense.
I couldn't get a display output from the PC itself and I was wary of pulling the drive when I don't know the drive structure but it seems that should be fine to use our normal Acronis tool. When you say that approach needs the robot rebooted a few times, is that because the PC needs powered down for the drive removal? Are there any risks to this approach? I've done it many times on normal PC's but I don't understand much of this system and they can't tolerate much downtime on it.
How is the KSR USB stick obtained? I've looked through one of the boxes that came with the machine and I can find a few disks some of which look like they can be used to restore the system but no sign of a USB stick so I'm wondering if that's to be purchased separately.
