I need to create a backup of my working OpenHab config on a Rpi microSD card before I stuff around and upgrade everything and probably break it.
How do I do it? Please don't tell me to use one of the literally dozens of guides saying to use Win32 Disk Imager, because me card looks like this.
I found one post with someone suggesting "Roadkil's DiskImage Version 1.6" which I am using now, but that had no replies. I found a few other people with the same issue (of a multiple partition SD card) but no obvious answers.
Other options
DD (on the Pi itself) : This also seems to assume a single partition, or needing to restore only a single partition. Yeah, it might work but I want to be able to dump one image back on a card to get a working image back.
Apparently there's an SD card copier added as well ( https://www.raspberrypi.org/blog/another-update-raspbian/ ) but again, it's not clear whether this will copy all partitions, or restore them...
Can anyone help me out with the easiest approach here? Will one of the options I have discarded actually do what I want without being an expert in Linux and knowing exactly how to recreate the CD card partitions of exactly the right size and type?
