How to Backup Amazon RDS Database?

What is Amazon RDS?

Amazon Relational Database Service (RDS) is a managed database platform provide by AWS. By using this service, companies can run databases such as MySQL, PostgreSQL, MariaDB, SQL Server, Oracle Database and Amazon Aurora without having to manually manage servers and infrastructure.

If you run a database server yourself, you have to:

• Purchase or rent a server
• Install and update the operating system
• Perform hardware maintenance
• Manage database patches and upgrades
• Monitor storage and infrastructure

But with Amazon RDS, AWS takes care of all these infrastructure-related duties. This frees up time for database administrators and developers to concentrate on developing databases and applications.

Many people think that when a database is hosted on RDS, AWS takes full responsibility for data protection and backups. However, that is not the case.

The AWS Shared Responsibility Model states that responsibility is shared between AWS and the customer.

Why Is It Important to Backup Amazon RDS?

Many businesses don’t realize how important backups are until an incident happens. Think about the following scenarios:

1. A Developer Removes Important Information

By mistake, a developer executes a DELETE query without the correct WHERE clause. In a matter of seconds, thousands of records vanish. It might be impossible to recover those records without a backup.

2. Data corruption caused by application bugs

A coding error in the software update causes customer information to be wrongly modified. Although the database is still accessible, the data is no longer useful.

3. Networked Systems Are Infiltrated by Ransomware

Corporate data can still be vulnerable by hacked credentials or malicious apps, even with Amazon’s infrastructure security protections. A point of recovery is provided by backup.

4. Unsuccessful Database Migrations

Database upgrades and schema changes can occasionally go wrong. If rollback procedures do not work as expected, then backup becomes the fastest recovery option.

5. Compliance Requirements

Industries such as healthcare, finance and legal services often require historical copies of business data for regulatory compliance.

How to Backup Amazon RDS Database?

There are several ways to create Amazon RDS backup. The right method depends on your recovery objective, retention requirements and operational preferences.

Method 1. Use Amazon RDS Automated Backups

Automated backups are the easiest way to protect RDS database. When enabled, Amazon RDS has the ability to automatically generate:

• Backups of databases every day
• Logs of transactions
• Points of recovery throughout the retention period

Restoration to a certain point in time is made possible by these backups.

How Automated Backups Work

RDS continuously records database changes and stores them in backup storage. If problems occurs, then AWS can reconstruct the database using:

• The latest backup
• Transaction logs generated after that backup

This provides more flexibility than relying on a single daily backup file.

How to Turn on Automated Backup

1. Launch the AWS Management console.
2. Go to the RDS Dashboard.
3. Select the instance of your database.
4. Click Modify.
5. Find the Backup Settings.
6. Click Save Changes after setting the backup retention period.

This is the simple way to protect your Amazon RDS database. It provides point-in-time recovery and is completely handled by AWS. But this method keeps backups in AWS and is not appropriate for long-term archival needs.

Method 2. Create Manual RDS Snapshots

A snapshot is the complete copy of your database at specific moment. Snapshots are accessible until you manually remove them. his makes them useful before major changes.

When Should You Create Snapshot?

Create a snapshot before:

• Database upgrades
• Schema modifications
• Application deployments
• Data migration projects

If something breaks then you can restore the database from that exact state.

Steps to Create RDS Snapshot

1. Open Amazon RDS Console.
2. Choose your database.
3. Click on Actions.
4. Choose Take Snapshot.
5. After entering the name of the snapshot, approve its creation.

This is advantageous for long-term retention but storage costs increase with time.

Method 3. AWS RDS Backup Using Native Database Tools

Many businesses outside of AWS maintain separate copies of their database. Native database backup tools are helpful in this situation.

You can make backups using the following methods, depending on your database engine:

Database Backup Instrument

MySQL – mysqldump

PostgreSQL – pg_dump

Native SQL Backup for SQL Server

MariaDB – mariadb-dump

These programs produce backup files that are portable.This is independent from AWS infrastructure and full control over backup files but it requires manual execution and coding knowledge.

Method 4. Automate Amazon RDS Backup to External Storage

Though the capabilities of RDS’ automated backups & snapshots on Amazon provide an excellent solution for retrieving data from within the AWS ecosystem, many businesses want to keep their extra backup copies outside the AWS environment for improved security and disaster recovery purposes. In those cases, utilizing specialized backup programs such as Prapl SQL Backup Tool is often the best way to go about it.

This tool will generate backup files by making a direct connection with your Amazon RDS database, then compress, encrypt, and transfer it to whatever kind of storage you choose. You might even set this to run on automatic basis, moving these backed-up databases directly onto local hard drives, NAS appliances, Amazon’s S3 storage service, an FTP server, or even over secure SFTP connections.

Steps to Backup Amazon RDS Database Automatically

Step 1. Run SQL Backup tool on your PC and click + New Backup.

Step 2. Select the relevant database type for your Amazon RDS instance and click Continue.

Step 3. Enter Host name, Port, Username, Password and Database name of your AWS RDS server and then click on Test Connection to verify.

Step 4. Choose destination location to store Amazon RDS backup.

Step 5. Set Backup type, Schedule and Retention as per your needs. After these configurations, click Save and Run Now to begin the backup process.

Which AWS RDS Backup method Should You Choose?

The best backup strategy depends on your recovery requirements.

Conclusion

Amazon RDS provides several methods for protecting database including automated backups, snapshots and native exports. Each method solves a different problem. Automated backups help with daily recovery, snapshots protect major changes and exported backups provide independence from AWS environment. On the other hand, professional backup software is the best way for maximum protection and backup scheduling. In this post, we have mentioned all these methods. Now, selection of the right method depends on user preferences.

Frequently Asked Questions
