If you self-host n8n, you have probably done this at some point:
export the workflow, rename the file, drop it in Drive, move on.
It works fine until you forget, and by then something is already gone.
I put together a workflow that runs every 10 hours instead.
It pulls all your workflows through the n8n API, converts each one to a JSON file, creates a dated folder in a Google Drive, uploads everything into it, then deletes the previous folder so old copies don't pile up. That is the whole thing.
No manual exports.
No digging through Drive trying to figure out which copy is current.
If you are on self-hosted n8n and not doing something like this, now is a good time to start.
Save this if you want to set it up later.
