Centralized Backup Management with AWS Backup - Backup Plans and Cross-Region Protection
Manage backups for EC2, RDS, DynamoDB, and more under a unified policy. Covers Vault Lock WORM protection and automated restore testing.
Overview of AWS Backup
AWS Backup is a service that centrally manages backups across multiple AWS services. Instead of individually managing each service's native backup features (EBS snapshots, RDS snapshots, DynamoDB backups), you can manage them uniformly through a single AWS Backup backup plan. Supported services include EC2, EBS, RDS, Aurora, DynamoDB, EFS, FSx, S3, Neptune, DocumentDB, Timestream, CloudFormation, SAP HANA on EC2, and over 15 others. It automates backup creation, retention, deletion, and cross-region copying on a policy basis.
Designing Backup Plans
A backup plan consists of backup rules (schedule, retention period, copy destination) and resource assignments (target resource selection). A common approach combines two rules: daily backups retained for 30 days and weekly backups retained for 1 year. Resource assignment is tag-based; for example, resources tagged with backup:daily are automatically included as backup targets. Adding cross-region copy to a rule executes a copy to the DR region simultaneously with backup creation. Retention periods in the copy destination region can be set independently, enabling cost optimization such as retaining only the last 7 days in the DR region.
Vault Lock and Restore Testing
Backup Vault Lock applies a WORM policy to a backup vault, preventing deletion of backups within the retention period. It eliminates the risk of backups being deleted in a ransomware attack and addresses regulatory requirements (such as SEC 17a-4). Automated restore testing is a feature that periodically verifies that restores from backups actually succeed. You define a schedule and target resources in a restore test plan and monitor restore success or failure through CloudWatch metrics. Since backups are meaningless if they can't be restored, regular execution of restore tests is a critical element of DR strategy. To learn AWS Backup from basics to advanced topics, books (Amazon) offer systematic coverage.
AWS Backup Pricing
AWS Backup pricing is based on backup storage volume. EBS snapshots cost approximately $0.05 per GB per month, RDS snapshots approximately $0.095 per GB per month, and EFS backups approximately $0.05 per GB per month. Cross-region copies incur additional storage charges in the destination region plus data transfer charges. There is no additional charge for using Vault Lock. Restore testing incurs charges for the runtime of restored resources, so it's important to include scripts that promptly delete resources after testing completes. Configure lifecycle policies to transition to cold storage and reduce long-term retention costs.
Summary
AWS Backup is a service that centrally manages backups across multiple services under a unified policy. It reduces management overhead with tag-based resource assignment, addresses compliance with Vault Lock, and verifies backup effectiveness with restore testing. Integration with Organizations enables organization-wide backup governance.
