Feature Request: Recover Full Node-RED State from Backup

I just stumbled upon this thread trying to resurrect my hosed Node-Red after an update…

This would be fine and dandy if there were not 10+ Nodes/flows that use the same base nodes. Look up MSSQL and figure out which one was the one previously installed… There are several that build upon a common base.

I would like to add my vote to a way to backup all of the installed nodes.
