aws-snapshot-tool vs AWS Backup: which should I use?

aws-snapshot-tool is better for lightweight, custom EBS backups with tag-based automation, while AWS Backup offers a fully managed service with broader resource support and simpler setup. Choose the tool if you prefer open-source control and cron scheduling, but opt for AWS Backup for enterprise-grade features and cross-service backups.

How to install aws-snapshot-tool on Ubuntu?

First, install Python and the Boto library via pip, then clone the GitHub repository. Follow the README steps to configure the config.py file with AWS credentials, SNS ARN, and retention settings. Finally, set up cron jobs using the provided examples to automate snapshot runs.

Does aws-snapshot-tool handle encrypted EBS volumes?

Yes, it should work with encrypted EBS volumes since AWS snapshots preserve encryption, but ensure the IAM policy includes permissions for KMS keys if used. The tool doesn't explicitly manage encryption, so verify AWS best practices for secure backup handling.

Can I use aws-snapshot-tool with multiple AWS accounts?

Not directly out of the box; it's configured for a single AWS account and region via the config.py file. For multi-account setups, you'd need to duplicate the script and configurations per account or modify it to assume roles, which adds complexity.

How to monitor failures in aws-snapshot-tool?

Rely on SNS notifications for success or failure alerts, and check AWS CloudTrail logs for API errors. Since it runs via cron, also monitor system logs for execution issues, and ensure the IAM policy has sufficient permissions to avoid silent failures.

What is aws-snapshot-tool?

aws-snapshot-tool is a Python script that automates the creation and rotation of Amazon EBS volume snapshots. It uses AWS tags to identify volumes for backup and allows users to configure retention policies for daily, weekly, and monthly snapshots. The tool integrates with cron jobs for scheduled execution and supports SNS notifications for monitoring.

Target Audience

AWS administrators and DevOps engineers who need to automate and manage EBS volume backups without relying on complex third-party services.

Value Proposition

It provides a lightweight, open-source alternative to AWS-native backup solutions, offering fine-grained control over snapshot retention and seamless integration with existing AWS infrastructure through simple tagging and cron scheduling.

Overview

A Python/Boto script that automates snapshot making of EBS volumes and rotating.

Use Cases

Best For

Automating EBS snapshot backups for tagged volumes
Implementing custom retention policies for daily, weekly, and monthly snapshots
Setting up cost-effective backup solutions without AWS Backup
Integrating snapshot notifications via Amazon SNS
Managing backups for multiple EBS volumes with minimal configuration
Scheduling snapshot creation using cron jobs in Linux environments

Not Ideal For

Environments requiring cross-region or multi-account snapshot management
Teams preferring serverless, event-driven backups using AWS Lambda or CloudWatch Events
Organizations needing to backup other AWS resources like RDS databases or EC2 instances

Pros & Cons

Pros

Tag-Based Automation

Uses AWS tags to automatically identify EBS volumes for snapshots, simplifying volume selection and reducing manual intervention.

Flexible Retention Policy

Allows configurable retention for daily, weekly, and monthly snapshots, providing granular control over backup history based on user needs.

SNS Notification Integration

Supports Amazon SNS out of the box for real-time notifications on snapshot activities, enhancing monitoring without extra setup.

Cron Job Compatibility

Designed to run as scheduled cron jobs, enabling hands-off automation and easy integration into existing Linux-based workflows.

Cons

Manual IAM Configuration

Requires users to manually create IAM policies and roles, which can be complex and error-prone compared to managed AWS services.

Limited to EBS Volumes

Only handles EBS volume snapshots, not extending to other AWS resources like RDS or EC2 instances, restricting its utility in broader backup strategies.

Setup Complexity

Involves multiple steps including Python and Boto setup, configuration file edits, and cron scheduling, which may be cumbersome for less experienced users.
