A simple script to backup a PostgreSQL DB to a Cloudflare R2 endpoint

  2. Create a bucket in R2 (make sure it is not public)
  3. Go to "Manage R2 API Tokens" and generate a token for your own bucket. Keep that around to add it to your environment variables

2. Configure environment variables

Configure your environment with environment variables that are shown in .env.sample.

cp .env.sample .env

3. Install pg_dump on the machine where you will run this script

4. Configure password for the user that will be used to connect to PostgreSQL
