Backup and Recovery Processes
Backup Process:
1. Data Classification and Prioritization:
We classify data based on sensitivity and criticality to the business.
Critical systems, customer data, and sensitive IP have the highest priority.
2. Backup Frequency and Types:
Full Backups: Conducted weekly for all critical systems.
Incremental Backups: Implemented daily to capture changes made since the last full or incremental backup.
Differential Backups: Performed every 48 hours to record data changes since the last full backup.
3. Backup Storage:
On-site Storage: For quick access and recovery.
Off-site Storage: Including cloud solutions (like AWS S3, Azure Blob Storage) for redundancy.
We use encrypted storage formats to ensure data security.
4. Backup Automation and Monitoring:
Automated backup schedules using tools like Veeam Backup & Replication and IBM Spectrum Protect.
Continuous monitoring using tools like Nagios to ensure backup completion and flag any issues.
Recovery Process:
1. Recovery Planning:
Developing and maintaining a comprehensive disaster recovery plan.
Regularly updating the recovery plan to reflect system updates and new threats.
2. Recovery Testing:
Conducting quarterly disaster recovery drills.
Testing various scenarios, including complete system failures, data corruption, and ransomware attacks.
3. Recovery Time and Recovery Point Objectives (RTO and RPO):
Establishing clear RTO and RPO for different types of data and systems.
Critical systems have an RTO of less than 2 hours and an RPO of 30 minutes.
4. System Redundancies:
Using redundant systems and architectures to ensure quick failover during a disaster.
Employing load balancers and replicated databases for high availability.
Tools and Technologies
Backup Tools: Veeam, IBM Spectrum Protect, and Acronis for robust backup capabilities.
Cloud Storage: AWS S3 and Azure for secure and scalable offsite storage.
Virtualization: VMware and Hyper-V for efficient management of virtual machine backups.
Monitoring: Nagios and Datadog for real-time monitoring of systems.
Encryption: Veracrypt and BitLocker for securing data at rest.
Enhancements for Speed and Efficiency
Automation: Automating backup and recovery processes wherever possible to reduce manual intervention and error.
Documentation: Maintaining detailed documentation and SOPs for quick reference during recovery operations.
Training: Regular training sessions for the IT team on the latest backup and recovery strategies and tools.
