This module, along with the lambda-share-snapshot and lambda-copy-shared-snapshot modules, can be used to backup your RDS database to another AWS account (e.g., for disaster recovery) on a configurable schedule. Under the hood, each module runs a Lambda function that instructs your database to take a snapshot (this module), share the snapshot with another account (the lambda-share-snapshot module), and make a copy of the snapshot (lambda-copy-shared-snapshot).

RDS architecture

Features


  • Standalone functions for taking snapshots, sharing snapshots, and copying snapshots that can be combined in many different ways

  • You can combine them to copy snapshots across AWS accounts and regions

  • Configurable backup schedule (e.g., using cron expressions)

  • Clean up old snapshots automatically using the lambda-cleanup-snapshots module.

This repo is a part of the Gruntwork Infrastructure as Code Library, a collection of reusable, battle-tested, production ready infrastructure code. If you’ve never used the Infrastructure as Code Library before, make sure to read How to use the Gruntwork Infrastructure as Code Library!

Core concepts

Repo organization

  • modules: the main implementation code for this repo, broken down into multiple standalone, orthogonal submodules.

    • modules/rds: use this module to deploy all non-Amazon databases, including MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server.

    • modules/aurora: use this module to deploy all Amazon’s Aurora and Aurora Serverless databases.

    • modules/lambda-create-snapshot: use this module and the other lambda-xxx-snapshot modules to create custom snapshots of your databases and copy those snapshots to other AWS accounts.

  • examples: This folder contains working examples of how to use the submodules.

  • test: Automated tests for the modules and examples.
