Back up your WordPress website to Amazon Web Services (AWS) S3 Bucket

In this blog, we are going to explain how to take a backup of WordPress site code and data onto an S3 bucket.


  • AWS account
  • SSH and DB Access to WordPress Server

Steps To Backup WordPress Site To AWS S3 Bucket

Step 1: Create an S3 bucket with a name: -backup.

Step 2: Create an IAM user with a name: wordpress-s3-backup-user and attach the following policy to this user.

    "Version": "2012-10-17",
    "Statement": [
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
            "Resource": [
            "Condition": {
                "IpAddress": {
                    "aws:SourceIp": ""

Step 3: Create a Read-only MySQL DB user with SELECT permission on all WordPress DB tables.

To do so, connect to MySQL DB and execute the following commands:

CREATE USER ‘wordpress_backupuser’@’localhost’ IDENTIFIED BY ”;

GRANT SELECT ON * . * TO ‘wordpress_backupuser’@’localhost’;

Step 4: SSH to the WordPress server and install AWS CLI. And also configure the CLI with credentials created in Step 2.

pip3 install aws cli –upgrade –user

touch test-aws-access.txt

aws s3 cp test-aws-access.txt s3://-backup

Step 5: Create the following S3 backup script with a name:

# MySQL Dump
mysqldump --single-transaction -u wordpress_backupuser -p -h localhost  > /tmp/wordpress-dump.sql
# Zip wordpress code
rm -rf /tmp/
zip -r /tmp/ /path/to/your/wordpress-root-dir
dy=`date --date="-1 day" '+%Y'`
dm=`date --date="-1 day" '+%m'`
dd=`date --date="-1 day" '+%d'`
# Copy to S3
/path/to/aws s3 cp /tmp/wordpress-dump.sql s3://-backup/$dy/$dm/$dd/db/
/path/to/aws s3 cp /tmp/ s3://-backup/$dy/$dm/$dd/code/

Step 6: Setup Cron Jobs to take backup periodically with the following Cron expression:

#crontab -e

# Executes backup script midnight of every day.
0 0 * * * /path/to/

Step 7: And Set Up an S3 bucket lifecycle rule to delete older backup data. This will help you with S3 storage cost.
