Backup disaster recovery automation strategies

Implement comprehensive backup and disaster recovery automation for business continuity and data protection. Backup strategies: 1. 3-2-1 rule: 3 copies of data, 2 different media types, 1 offsite location. 2. Recovery objectives: RTO (Recovery Time Objective) <4 hours, RPO (Recovery Point Objective) <1 hour. 3. Backup types: full (weekly), incremental (daily), differential options based on data change rate. Automated backup systems: 1. Database backups: automated SQL dumps, point-in-time recovery, transaction log backups. 2. File system backups: rsync, duplicity for encrypted backups, snapshot-based backups. 3. Application data: configuration backups, state snapshots, user data preservation. Cloud backup solutions: 1. AWS Backup: cross-service backup management, automated backup policies, compliance reporting. 2. Azure Backup: VM backups, SQL Server backup, file/folder level recovery. 3. Google Cloud Backup: automated VM snapshots, database backup scheduling. Disaster recovery planning: 1. Failover automation: DNS switching, load balancer reconfiguration, database promotion. 2. Recovery testing: monthly DR drills, automated failover testing, recovery time validation. 3. Documentation: runbooks, contact lists, escalation procedures, vendor contacts. Data validation: 1. Backup verification: restore testing, data integrity checks, backup completion monitoring. 2. Compliance: retention policies (7 years for financial data), encryption requirements. Monitoring and alerting: backup success/failure notifications, storage capacity monitoring, restore time tracking, compliance dashboard with audit trails.
