PostgreSQL Backup to Supabase Storage

This is a tool that lets you backup your PostgreSQL database to Supabase Storage. The tool runs as a Docker container and can be scheduled to run at specific times using a cron service like Render.com.

Prerequisites

Docker
A PostgreSQL database to backup
A Supabase account and Storage bucket

Installation

Clone this repository
Build the Docker image: docker build -t backup-to-supabase .

Configuration

The following environment variables are required:

SUPABASE_PROJECT_ID: The unique ID of your Supabase project
SUPABASE_SERVICE_KEY: A service key for your Supabase project (see Supabase docs)
DATABASE_URL: The URL of the PostgreSQL database to backup

The following environment variable is optional:

SUPABASE_BUCKET_NAME: The name of the Supabase Storage bucket to store the backups in. Defaults to database-backups.

You can set these environment variables by creating a file called .env in the root directory of this project, with the following content:

SUPABASE_PROJECT_ID=your_project_id
SUPABASE_SERVICE_KEY=your_service_key
SUPABASE_BUCKET_NAME=your_bucket_name # defaults to 'database-backups'
DATABASE_URL=your_database_url

Alternatively, you can set these environment variables using the method recommended by your hosting provider.

Usage

To run the backup process manually, you can use the following command:

docker run --rm --env-file .env backup-to-supabase

To schedule the backup process to run at specific times, you can use a cron service like Render.com. In Render.com, create a new cron job and set the command to:

docker run --rm --env-file /path/to/your/.env backup-to-supabase

Set the schedule to the desired frequency (e.g. daily, weekly) and the timezone to your local timezone.

For example, a cron schedule that would execute 6 minutes past every 12 hours would be
