• Initial Configuration: Setting Up Your Amazon S3 Account
• Method 1: Using Duplicator for WordPress Backups to S3 (Highly Customizable)
• Method 2: Using UpdraftPlus for WordPress Backups to S3 (Free Solution)

Initial Configuration: Setting Up Your Amazon S3 Account

Before backing up your WordPress site to Amazon S3, you need to properly configure your storage environment.

Step 1: Create an Amazon S3 Bucket

Begin by logging into your Amazon Web Services (AWS) account. Click the menu button in the top left corner and select 'S3.'

On the S3 dashboard, locate and click the 'Create bucket' button.

An Amazon S3 bucket functions as a container for your files. Consider it a specialized folder that will store all your WordPress backup archives.

Select 'General purpose' for the 'Bucket type.' Then assign a unique name to your bucket.

Using your domain name is recommended for uniqueness, such as backups.yourdomain.com.

Note the selected 'AWS Region' (for example, 'US East N. Virginia'), as you may need to specify this same region in your WordPress plugin configuration later.

You can maintain default values for the remaining settings.

Scroll to the bottom of the page and click 'Create bucket.' Your new storage container will be ready within moments.

Step 2: Establish a Security Policy

Next, configure a security policy for your backups. This policy defines rules governing what actions can be performed on your backup files.

Return to the menu and select 'IAM' to access AWS's security management interface.

Navigate to the 'Policies' page and click 'Create policy' to define your backup permissions.

In the policy editor, select the 'JSON' tab to input security rules.

Copy and paste the following policy code into the editor. This JSON configuration specifies exactly what permissions your backup plugin will have:

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:ListBucket", "s3:GetBucketLocation", "s3:ListBucketMultipartUploads" ], "Resource": "arn:aws:s3:::BUCKETNAME", "Condition": {} }, { "Effect": "Allow", "Action": [ "s3:AbortMultipartUpload", "s3:DeleteObject", "s3:DeleteObjectVersion", "s3:GetObject", "s3:GetObjectAcl", "s3:GetObjectVersion", "s3:GetObjectVersionAcl", "s3:PutObject", "s3:PutObjectAcl" ], "Resource": "arn:aws:s3:::BUCKETNAME/*", "Condition": {} }, { "Effect": "Allow", "Action": "s3:ListAllMyBuckets", "Resource": "*", "Condition": {} } ] }

This configuration enables your backup plugin to list files in your backup bucket and perform operations like adding, retrieving, and deleting backup files within it. The policy restricts the plugin from performing other actions, maintaining account security.

Scroll down the page and click 'Next.'

Assign a descriptive name to your policy, such as WordPress-Backup-Policy,Duplicator-Backup-Policy, or UpdraftPlus-Backup-Policy. Choose a name that clearly indicates the policy's purpose. This policy will function effectively with either WordPress backup plugin discussed in subsequent sections.
