Backup PostgreSQL Database In AWS - Steps

Overview

This document provides step-by-step instructions on how to take backups of PostgreSQL databases hosted on AWS.

Pre-requisites

• Access to an AWS account with permissions to manage Amazon RDS instances.

• PostgreSQL database hosted on Amazon RDS.

Steps

Step 1: Navigate to the Amazon RDS Console:

• Log in to the AWS Management Console.

• Go to the Amazon RDS service.

Step 2: Select the PostgreSQL Instance:

• From the list of DB instances, select the PostgreSQL instance for which you want to take the backup.

Step 3: Enable Automated Backups (Optional):

• If automated backups are not already enabled, navigate to the "Backup" tab of the RDS instance.

• Click on "Modify" and enable automated backups.

• Configure the backup retention period according to your requirements.

Step 4: Manually Trigger a Snapshot:

To create a manual snapshot, select the RDS instance you want to back up. Click on the Actions button in the right upper corner and select Take a snapshot.

This will redirect you to a page like the one below.

Provide a meaningful name for the snapshot and click “Create snapshot”.

This will create a manual snapshot of the DB instance that you created.

Step 5: Create a Manual Backup Using pg_dump:

• Connect to the PostgreSQL database using a PostgreSQL client tool or command-line interface.

• Use the pg_dump command to export the database to a file:

  bashCopy codepg_dump -h <hostname> -U <username> -d <database_name> -f <backup_file_name>.sql

  Replace <hostname>, <username>, <database_name>, and <backup_file_name> with the appropriate values.

Step 6: Copy Backup Files to Amazon S3 (Optional):

• If desired, copy the backup files to Amazon S3 for long-term storage and redundancy.

• Use the AWS CLI or SDKs to upload the files to an S3 bucket.
