Server-Level Recovery Strategy Documentation

1. Introduction

  This document outlines the recovery strategy for MongoDB and InfluxDB databases, as well as backend applications, all hosted on AWS instances. It covers procedures for both normalized and compromised (hacked) operational scenarios.

2. Objectives

1. Minimize data loss
2. Ensure high availability
3. Quick recovery
4. Compliance with legal and business requirements

3. Components Involved

• MongoDB Database
• InfluxDB Database
• Backend Application
• AWS EC2 Instances
• AWS S3 Buckets (for backups)
• Network Components (VPC, Security Groups)
• AWS CloudWatch (for monitoring)

4. Backup Strategy

4.1 Full Backup

• Frequency：Weekly, every Sunday at 12:00 AM
• Tools and Commands：
  1. MongoDB: mongodump --db our_database
  2. InfluxDB: influxd backup /path/to/backup
  3. AWS S3: Use S3 CLI to copy backups to an S3 bucket

4.2 Incremental Backup

• Frequency：Daily, at 2:00 AM
• Tools and Commands：
  1. MongoDB: mongodump with --oplog option
  2. InfluxDB: Back up only the changed data
  3. AWS S3: Use S3 CLI with sync option

5. Restore Strategy

5.1 Full Restore

• Estimated Time：4 hours
• Steps and Commands：
  1. Restore MongoDB: mongorestore --db our_database /path/to/backup
  2. Restore InfluxDB: influxd restore -portable /path/to/backup
  3. Deploy Backend: Use AWS Elastic Beanstalk or manual deployment

5.2 Partial Restore

• Estimated Time：2 hours
• Steps and Commands
  1. Restore specific MongoDB collection: mongorestore --collection our_collection --db your_database /path/to/backup
  2. Restore specific InfluxDB measurement: Extract and restore only relevant data
  3. Roll back specific backend services using version control

6. Failover and Redundancy

• MongoDB Replica Sets
• InfluxDB High Availability
• AWS EC2 Auto Scaling for backend

7. Monitoring and Auditing

• AWS CloudWatch for system and database monitoring
• Enable auditing features in MongoDB and InfluxDB

8. Procedures for Normalized Operations

• Monitoring via CloudWatch
• Routine backups
• Testing backups
• Patching and updates

9. Procedures for Hacked Scenarios

• Isolate affected AWS instances
• Conduct forensic analysis
• Restore from the latest clean backup
• Strengthen security measures

10. Testing the Recovery Plan

• Perform tests quarterly on a separate AWS environment

11. Revision and Update Schedule

• Semi-annually or after significant changes to the AWS architecture

12. Appendices

• AWS IAM policies for backup and restore
• MongoDB and InfluxDB configuration files
• Emergency Contact Information
