There is a guide on how to backup PSQL to AWS.
Is there a script to back up Render’s PSQL to Google Storage?
Or even better, is it possible to use Docker scripts to back it up to Google Storage (for example GitHub - jamiebishop/postgres-docker-gcs-backup: Backup postgres databases in a docker container to Google Cloud Storage.).
Thanks for reaching out.
We don’t have a specific example to backup Postgres to Google Cloud Storage. However, the project you shared seems to be precisely what you describe. As a Dockerized project, you could likely set it up as a Cron Job on Render (in the same region as your Postgres instance) and fill in the environment variables as required.
