Looking for some different options: I have a piece of equipment that's run by an embedded PC (Win10). I'm looking for 2-3 different ways to keep a scheduled backup that's complete enough to be a fully bootable duplicate. Once a week, or maybe even once a month, will be sufficient. I might be able to get a RAID 1 array inside the PC - it's an industrial PC that's designed specifically for embedded systems, so it has a small form factor and might not be able to support more than one internal HDD. I still need to get some detailed specs on that computer. I could probably add a second, external, HDD and use a cloning utility. I could probably do a few other things, too. I'm not the one that's making the specifics for this requirement, so I'm still trying to find out if the backup must be kept attached to the PC or will be saved offsite somewhere. I know that can make a difference. Possibly RAID 1 and another drive? Knowing what I do know, I am assuming this backup will have to be as automatic and behind the scenes as possible, with very little user input (so attaching an external drive, doing a backup, and then locking away that drive is probably not going to work). This equipment will not, ever, be attached to a network. It will remain a stand-alone system.
