Initial Configuration: Setting Up Your Amazon S3 Account

Properly configuring your Amazon S3 storage is essential before establishing WordPress backups. This section guides you through creating a storage bucket and implementing security policies.

Step 1: Create an Amazon S3 Storage Bucket

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

On the S3 dashboard, locate and click the 'Create bucket' button. An S3 bucket functions as a container for your files—think of it as a dedicated folder that will house all your WordPress backup data.

Select 'General purpose' as your bucket type. Choose a unique name for your bucket; using your domain name (e.g.,backups.yourwebsite.com) helps maintain organization.

Note the selected 'AWS Region' (such as 'US East N. Virginia'), as you may need to specify this region within your WordPress plugin configuration later. You can retain the default settings for remaining options.

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

Step 2: Establish a Security Policy

Next, create a security policy to govern access to your backup files. This policy defines specific permissions for managing your backup data.

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

Navigate to the 'Policies' section and click 'Create policy.' This is where you'll define permissions for your backup operations.

In the policy editor, select the 'JSON' tab to input security rules. Copy and paste the following policy code into the editor, replacing 'BUCKETNAME' with your actual bucket name:

{ "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 JSON configuration enables your backup plugin to list files within your bucket and perform essential operations like adding, retrieving, and deleting backup files while restricting other actions to maintain account security.

Scroll down and click 'Next.' Provide a descriptive name for your policy, such as WordPress-Backup-Policy,Duplicator-Backup-Policy, or UpdraftPlus-Backup-Policy. Choose a name that clearly identifies its purpose. This policy will function effectively with either WordPress backup plugin discussed in subsequent sections.
