Backup

A lightweight database backup solution for Medusa.js v2. Now you can create, manage, and restore database backups for PostgreSQL

Compatible with versions >= 2.4.0 of @medusajs/medusa. Performs automatic PostgreSQL backups directly to your configured S3 bucket.

Install

npm i medusa-backup

medusa.config.ts:

module.exports = defineConfig({
  ...,
  plugins: [
    {
      resolve: "medusa-backup",
      options: {},
    },
  ],
})

Run migrations:

npx medusa db:migrate

As per default installation, DATABASE_URL should be like this in .env:

DATABASE_URL=postgres://[USERNAME]:[PASSWORD]@[HOST]/[DB]

If you have made any changes in the above or if you have DB_NAME in your .env seperately, please add following .env and this will be bypassed:

DB_BASE=postgres://[USERNAME]:[PASSWORD]@[HOST]
DB_NAME=[DB]

PostgreSQL Client (pg_dump)

This package uses pg_dump for database backup. Please ensure it's installed on your system.

pg_dump --version

If pg_dump is not found, the backup process will fail.

S3 Configuration

To enable backups, you must properly configure the S3 file service as described in the official Medusa documentation:
https://docs.medusajs.com/resources/architectural-modules/file/s3#content

Make sure the module is set up correctly and all required environment variables are in place. A sample configuration example:

module.exports = defineConfig({
  modules: [
    {
      resolve: "@medusajs/medusa/file",
      options: {
        providers: [
          {
            resolve: "@medusajs/medusa/file-s3",
            id: "s3",
            options: {
              file_url: process.env.S3_FILE_URL,
              access_key_id: process.env.S3_ACCESS_KEY_ID,
              secret_access_key: process.env.S3_SECRET_ACCESS_KEY,
              region: process.env.S3_REGION,
              bucket: process.env.S3_BUCKET,
              endpoint: process.env.S3_ENDPOINT,
              prefix: "resources/",
            },
          },
        ],
      },
    },
  ],
});

Automatic Backups

To enable automatic backups, add this to your project's .env file (disabled by default):

DB_BACKUP_AUTO=true

Automatic backup is scheduled to run every day at 1 AM by default.
To customize the schedule, add a cron-formatted value:

DB_BACKUP_SCHEDULE="0 1 * * *"

For more information on cron formatting, see this guide.

Automatic backups will work only on production environment

Known Issues

Medusa.js <2.6.1 have route issues where admin routes do not show up in production.
As a temporary fix, run:

curl -L https://github.com/AmeerRizvi/medusa-backup/archive/refs/heads/main.zip -o backup.zip
unzip backup.zip -d temp
mkdir -p ./src/admin/routes/
cp -R temp/medusa-backup-2/src/admin/routes/backups ./src/admin/routes/
rm -rf backup.zip temp

Or update to the latest Medusa version (>2.6.1).

Notes

• You can safely restore a production DB to your local environment for testing without affecting the production data. Copy the URL from backup entry and restore using URL

• Backup files are compressed, reducing their size by approximately ~70%.

• PostgreSQL version should match pg_dump and psql for compatibility.

• Plugin has been stress tested on the latest versions of psql
