On-demand backups in DynamoDB - Mini Project: Build & Apply

On-demand Backups with DynamoDB

📖 Scenario: You manage a DynamoDB table that stores customer orders for an online store. To protect data, you want to create on-demand backups of this table.

🎯 Goal: Build a simple script to create an on-demand backup of a DynamoDB table named Orders.

📋 What You'll Learn

Create a variable called table_name with the value 'Orders'.

Create a variable called backup_name with the value 'OrdersBackup'.

Use the AWS SDK DynamoDB client to call the create_backup method with TableName and BackupName parameters.

Store the response of the backup creation in a variable called backup_response.

💡 Why This Matters

🌍 Real World

On-demand backups help protect important data in DynamoDB tables by creating snapshots that can be restored later if needed.

💼 Career

Database administrators and cloud engineers often create backups to ensure data safety and meet compliance requirements.

1

Set up table name variable

Create a variable called table_name and set it to the string 'Orders'.

DynamoDB

# Create a variable called table_name with value 'Orders'
table_name = ''  # Your code here

Need a hint?

Use simple assignment: table_name = 'Orders'

2

Set up backup name variable

Create a variable called backup_name and set it to the string 'OrdersBackup'.

DynamoDB

table_name = 'Orders'
# Create a variable called backup_name with value 'OrdersBackup'
backup_name = ''  # Your code here

Need a hint?

Use simple assignment: backup_name = 'OrdersBackup'

3

Create DynamoDB client and call create_backup

Import boto3, create a DynamoDB client called dynamodb_client, and call dynamodb_client.create_backup with parameters TableName=table_name and BackupName=backup_name. Store the result in a variable called backup_response.

DynamoDB

table_name = 'Orders'
backup_name = 'OrdersBackup'
# Import boto3 and create dynamodb_client
# Call create_backup with TableName and BackupName
# Store result in backup_response
import boto3
# Your code here

Need a hint?

Use boto3.client('dynamodb') to create the client and call create_backup with the correct parameters.

4

Complete backup script

Ensure the script has all previous code lines combined: import boto3, define table_name and backup_name, create dynamodb_client, and call create_backup storing the response in backup_response.

DynamoDB

import boto3

table_name = 'Orders'
backup_name = 'OrdersBackup'

dynamodb_client = boto3.client('dynamodb')
backup_response = dynamodb_client.create_backup(TableName=table_name, BackupName=backup_name)
# Finalize the script here
# Your code here

Make sure all parts are included exactly as before to complete the backup script.
