I do not know how to backup Openhab 2 on Raspberry Pi 3 with Razberry module. It is important to me that I could put the system back on schedule after a failure.
I am also not sure if there data to be backup on the Razberry module as well. Backup of Razberry module? or is all the data stored in the raspberry?
What needs to be considered and how do you backup your system?
Do you have any tips for good tool to backup openhab 2?
Sorry, don’t have experience with the razberry module, but would expect that this covers your needs:
If you use raspberry pi with sd-card, in my opinion, the easiest way to backup is to copy the SD card.
The safer approach would be to run Amanda as also mentioned in that link you included. It’s part of openHABian. openHABian you can install on top of almost any Linux, be it just in order to get Amanda setup.
It’s either way worth reading that README. It also points to the ZWay software that you can and should use on RaZberries to backup the controller’s content.
