How to backup MySQL database to Amazon S3

To backup MySQL databases to Amazon S3, you need to follow the following steps. But before that, you need to complete a few pre-tasks to make the backup process smoother.

✍ Prerequisites:
• Create an AWS Account
• Setting up a IAM user

How to backup MySQL to Amazon S3

The MySQL server from which you want to back up your databases must first have the AWS CLI tool installed. A command-line tool for managing your AWS services is the AWS CLI. It enables script-based automation and command-line management of numerous AWS services.

✽ Install AWS CLI

1. Utilize the command below to download the AWS CLI:

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

2. Install the downloaded file by using the following command after unzipping it:

unzip awscliv2.zip
sudo ./aws/install

3. You must configure AWS CLI with your AWS credentials after the installation.

aws configure

4. As indicated below, provide your AWS access key ID, secret key, and region.

AWS Access Key ID [None]: YOUR-AWS-ACCESS-KEY

AWS Secret Access Key [None]: YOUR-AWS-SECRET-KEY

Default region name [None]: us-east-1

Default output format [None]:

Backup MySQL to Amazon S3 manually

1. Log in to the MySQL console with the following command:

mysql -u root -p

2. Use the following command to list all databases on the server after logging into MySQL.

+--------------------+
| Database           |
+--------------------+
| db1                |
| db2                |
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+

3. Now, Use the following command to now quit the MySQL console:

mysql> EXIT;

4. Use the mysqldump utility to create a backup of any chosen MySQL databases from the above list.

mysqldump -u root -p db1 > db1_backup.sql

mysqldump -u root -p db2 > db2_backup.sql

mysqldump -u root -p --all-databases > all_databases.sql

5. To back up your MySQL database to AWS S3, use the following syntax:

aws s3 cp [your-db-name] "s3://your-s3-bucket-name"

6. Use the following command to list all databases on the AWS S3 bucket:

aws s3 ls "s3:// your-s3-bucket-name "

Lastly, by connecting into the Amazon Web Console, searching for S3, and selecting your bucket name, you can also confirm all databases.

Automatically backup MySQL database to Amazon S3

To automatically back up MySQL database to Amazon S3, follow these simple steps.

1. Perform this backup via mysqldump:

sudo mysqldump sakila | gzip > sakila.gz

2. Use the utility you previously installed to upload the backup into a bucket.

aws s3 cp sakila.gz s3:///mysql-backup/

3. Finally, it will be helpful to set up a cron task to perform backups on a regular basis and upload them to S3.

sudo crontab -e

4. There, you can add a string that creates a backup with a special name every 24 hours at midnight. So, you'll receive a fresh backup on S3 every evening.

0 */24 * * * sudo mysqldump sakila | gzip > `date +"%Y-%m-%d"-sakila.gz` && aws s3 cp `date +"%Y-%m-%d"-sakila.gz` s3:///mysql-backup/
