Backup, Retention & Disaster Recovery
Backup, retention, and disaster recovery (DR) strategies are essential to protect data, ensure compliance, and maintain business continuity. SecureCart implements cost-effective, scalable, and automated backup solutions to minimize data loss and downtime.
✔ Why SecureCart Needs Backup, Retention & DR Strategies?
Ensures recovery of customer transactions and order history in case of failures.
Minimizes downtime and data loss with automated backups and replication.
Meets compliance and regulatory requirements for data retention.
Optimizes storage costs by using lifecycle policies and archival strategies.
🔹 Step 1: AWS Backup & Retention Strategies
AWS offers fully managed backup services that SecureCart utilizes to automate backup retention and lifecycle management.
AWS Backup Service
Best Use Case
Cost Optimization Strategy
SecureCart Implementation
AWS Backup
Centralized backup for RDS, DynamoDB, EBS, and S3.
Automates backup schedules & lifecycle policies.
SecureCart uses AWS Backup for all production workloads.
Amazon RDS Automated Backups & Snapshots
Point-in-time recovery for RDS databases.
Stores backups in cost-effective S3 storage.
SecureCart enables automated daily backups for order management.
Amazon DynamoDB PITR (Point-in-Time Recovery)
Restores NoSQL tables to any second in the last 35 days.
Prevents accidental data loss without excessive retention.
SecureCart enables PITR for product catalog and user sessions.
Amazon S3 Versioning & Lifecycle Policies
Manages object versions and transitions data to cost-efficient storage.
Moves infrequently accessed data to Glacier.
SecureCart stores historical logs in S3 Glacier Deep Archive.
Amazon EBS Snapshots
Backups of EC2 volumes for disaster recovery.
Uses incremental snapshots to save costs.
SecureCart schedules EBS snapshots for all compute resources.
✅ Best Practices: ✔ Use AWS Backup to centralize and automate backup retention. ✔ Enable RDS and DynamoDB PITR for quick recovery of database transactions. ✔ Use S3 Lifecycle Policies to transition old backups to Glacier. ✔ Regularly test backup restoration to ensure recoverability.
🔹 Step 2: Disaster Recovery (DR) Strategies for Business Continuity
✔ SecureCart applies DR strategies to ensure minimal downtime and data recovery in case of failure.
Disaster Recovery Strategy
Recovery Time Objective (RTO)
Recovery Point Objective (RPO)
SecureCart Implementation
Backup & Restore
High (hours to days)
Medium (last backup)
SecureCart stores S3 backups in Glacier for cost-efficient DR.
Pilot Light (Minimal Standby Environment)
Medium (minutes to hours)
Low (frequent syncs)
SecureCart maintains a small EC2 & RDS replica in another region.
Warm Standby (Smaller-Scale Running System)
Low (minutes)
Very Low (near real-time)
SecureCart uses cross-region replication for databases & caches.
Active-Active Failover (Full Load Balancing Across Regions)
Immediate (seconds)
Zero (synchronous replication)
SecureCart uses Route 53 failover for highly available services.
✅ Best Practices: ✔ Choose the right DR strategy based on workload criticality and cost. ✔ Use cross-region replication for mission-critical workloads. ✔ Regularly test DR failover procedures to ensure reliability. ✔ Use AWS Route 53 for automatic failover between regions.
🔹 Step 3: Cross-Region & Cross-AZ Data Replication
✔ SecureCart replicates data across AWS regions and Availability Zones (AZs) to enhance resilience.
Replication Method
Purpose
SecureCart Implementation
Multi-AZ RDS Deployments
Ensures database availability by replicating across AZs.
SecureCart runs RDS in Multi-AZ mode for production databases.
Amazon DynamoDB Global Tables
Enables low-latency NoSQL replication across regions.
SecureCart ensures order history is available in multiple regions.
Amazon S3 Cross-Region Replication (CRR)
Ensures data availability in multiple AWS regions.
SecureCart replicates product images to multiple S3 buckets.
Amazon EFS Replication
Ensures fast failover for shared file systems.
SecureCart maintains application logs across multiple regions.
✅ Best Practices: ✔ Use Multi-AZ for high-availability RDS deployments. ✔ Enable DynamoDB Global Tables for low-latency read/write access across regions. ✔ Use S3 Cross-Region Replication for durability and compliance. ✔ Replicate EFS volumes for fast application recovery.
🔹 Step 4: Monitoring & Managing Backup Costs
✔ SecureCart ensures cost-efficient backup and DR strategies using AWS monitoring tools.
AWS Monitoring Tool
Purpose
SecureCart Implementation
AWS Cost Explorer
Tracks backup spending trends.
SecureCart analyzes Glacier storage costs to optimize retention policies.
AWS Backup Reports
Audits backup compliance and usage.
SecureCart ensures all critical services are backed up per policy.
Amazon CloudWatch
Monitors backup completion & recovery success.
SecureCart sets alerts for failed backup jobs.
AWS Budgets
Prevents excessive backup storage costs.
SecureCart sets budget alerts for Amazon S3 and Glacier storage usage.
✅ Best Practices: ✔ Use AWS Backup Reports to track compliance with DR policies. ✔ Monitor AWS Cost Explorer to analyze backup expenses. ✔ Set AWS Budgets to track and prevent excessive storage costs.
🚀 Summary
✔ Use AWS Backup to automate backup retention for databases, S3, and EBS. ✔ Implement disaster recovery strategies (Backup & Restore, Pilot Light, Warm Standby, Active-Active) based on workload criticality. ✔ Enable Multi-AZ and Cross-Region Replication for high availability. ✔ Optimize backup storage by using S3 Lifecycle Policies and Glacier Deep Archive. ✔ Monitor and manage backup costs with AWS Cost Explorer, CloudWatch, and AWS Budgets.
