Magento 2 Database Backup in Adobe Commerce Cloud is crucial to ensuring data security and protecting against data loss. In Adobe Commerce Cloud, the process of creating a database backup is simple, but it’s important to follow the right steps to avoid issues. In this guide, we will walk you through how to generate a database dump in Adobe Commerce Cloud.

Why Should You Get a Database Dump?

Before we dive into the steps, let’s quickly review why performing a database dump in Magento 2 is essential:

• Data Backup and Recovery: Protect your store’s data from accidental deletion, corruption, or unexpected issues by creating a secure backup.
• Environment Migration: Easily transfer your database across different environments (such as from staging to production) to ensure consistency.
• Development and Testing: Utilize real data in your development and testing environments to create more accurate simulations and improve overall testing quality.

Magento 2: How to Create a Database Backup in Adobe Commerce Cloud

Option 1: Database Backup in Adobe Commerce Cloud with ECE-Tools (Recommended)

One of the easiest and most efficient ways to create a database backup in Adobe Commerce Cloud is by using the ECE-Tools command-line utility. This tool simplifies the backup process and ensures you capture all essential data.

Option 1: db-dump (ece-tools; recommended)

To back up your database using ECE-Tools, follow these steps:

vendor/bin/ece-tools db-dump

Magento’s official documentation recommends this command as the most secure way to create a database backup. It ensures that your eCommerce site stays protected while the database is being dumped by:

1. Prompting for necessary permissions.
2. Automatically switching to maintenance mode.
3. Stopping all CRON jobs to avoid clashes with ongoing database operations.

This approach minimizes the risk of data corruption or inconsistency during the backup process.

Option 2: mysqldump

mysqldump -h <host> -u <username> -p <password> --single-transaction <db_name> | gzip > /tmp/<dump_name>.sql.gz

I am attaching a screenshot of the warning from the official Adobe Commerce Cloud portal. Please ensure that this warning is considered before proceeding with the mysqldump command to avoid potential issues.

When you generate a database backup using the mysqldump command, it’s important not to store the backup file in the /tmp directory. This directory has limited storage, and filling it up could lead to performance issues or even failures in the backup process. Instead, direct the backup to a secure location with ample storage space.

Retrieving Database Credentials via the MAGENTO_CLOUD_RELATIONSHIPS Variable

In Adobe Commerce Cloud, you can access your database credentials by using the MAGENTO_CLOUD_RELATIONSHIPS environment variable. This variable provides essential information, such as the database host, username, and password, allowing you to run the mysqldump command without hardcoding credentials.

Here’s how to retrieve and use the credentials dynamically:

export DB_CREDENTIALS=$(echo $MAGENTO_CLOUD_RELATIONSHIPS | base64 --decode | jq -r '.database[0]')
export DB_HOST=$(echo $DB_CREDENTIALS | jq -r '.host')
export DB_USER=$(echo $DB_CREDENTIALS | jq -r '.username')
export DB_PASSWORD=$(echo $DB_CREDENTIALS | jq -r '.password')

After retrieving the credentials, you can execute the mysqldump command safely without storing anything in /tmp, ensuring your environment remains stable.

Pro Tip: Store Backups Securely

Instead of using /tmp, consider saving your database backups in a more secure and spacious directory or uploading them to cloud storage services like AWS S3 or Google Cloud Storage. This ensures that you always have access to backups, and it avoids any unnecessary strain on your environment’s temporary storage.

Option 3: magento-cloud db:dump Command

The magento-cloud db:dump command allows you to retrieve and store your Magento 2 database locally in your current environment. For a more efficient backup, you can use the –gzip flag to reduce the file size. Additionally, you can specify the –environment flag to back up the database from a specific environment (e.g., production, staging, or development).

To execute this command, you must first install the Adobe Commerce Cloud CLI on your local machine. This tool is essential for managing Magento 2 databases and cloud environments efficiently.

  magento-cloud db:dump -e staging -f db-dump.sql

Taking regular backups of your database in Adobe Commerce Cloud is an essential practice to ensure the security and stability of your online store. By following the outlined steps, you can easily create backups that protect your valuable data and provide peace of mind in case of unexpected events. Always remember to store your backups in a safe and reliable location. With Adobe Commerce Cloud’s advanced tools and seamless integration, managing your backups has never been more efficient. Keep your store running smoothly and securely with proactive backup strategies.
