Implementing Backup Strategies

Overview

Design and implement backup strategies for databases, file systems, and cloud resources using tools like tar, rsync, pg_dump, mysqldump, AWS S3, and cloud-native snapshot APIs. Covers full, incremental, and differential backup schemes with retention policies, encryption, and automated verification.

Prerequisites

• tar, rsync, or restic installed for file-level backups
• Database client tools (pg_dump, mysqldump, mongodump) for database backups
• AWS CLI configured with S3 write permissions (or equivalent GCP/Azure storage access)
• Sufficient storage capacity at backup destination (local, NFS, or object storage)
• Cron or systemd timer access for scheduling automated backups
• GPG or OpenSSL for backup encryption at rest

Instructions

1. Inventory all data sources requiring backup: databases, application data directories, configuration files, secrets/certificates
2. Classify data by RPO (Recovery Point Objective) and RTO (Recovery Time Objective) requirements
3. Select backup strategy per data class: full daily + incremental hourly for databases, snapshot-based for block storage, rsync for file systems
4. Generate backup scripts using appropriate tools (pg_dump --format=custom, tar czf, rsync -avz --delete)
5. Configure retention policy: daily backups kept 7 days, weekly kept 4 weeks, monthly kept 12 months
6. Add encryption for backups containing sensitive data (gpg --encrypt or S3 server-side encryption with KMS)
7. Set up automated scheduling via cron jobs or systemd timers with proper logging
8. Implement backup verification: restore to a test environment on a weekly schedule and validate data integrity
9. Configure alerting for backup failures via email, Slack, or PagerDuty

Output

• Backup shell scripts with logging, error handling, and lock files to prevent concurrent runs
• Cron entries or systemd timer/service unit files
• Retention policy configuration (lifecycle rules for S3, cleanup scripts for local)
• Restore runbook with step-by-step recovery procedures
• Monitoring configuration for backup success/failure alerts

Error Handling

Examples

• "Create a backup strategy for a PostgreSQL database: full dump nightly to S3, WAL archiving for point-in-time recovery, 30-day retention."
• "Generate rsync scripts to mirror /var/www to a remote NAS with incremental daily backups and weekly full backups."
• "Implement encrypted backups for a MongoDB replica set with automated restore testing every Sunday."
