Complete backup of NodeRed configuration

Hello all,

My NodeRed is running on a RasPi. (version 0.18.3)
I don't have a backup at the moment...

I want to update to the latest version (version 0.19)
Therefor, i want to have a complete backup of my installation before doing so.
I can copy the SD card, but i was wondering if there exists a simplier method doing so. (without stopping the flows)

already thanks!
Koen.

do a search for backup in this forum and you should find a thread including a flow that will help you
