Goal
Implement and verify the complete Backup & Disaster Recovery infrastructure for SciDEX, including automated backups, S3 sync with lifecycle rules, integrity verification, alerting, and emergency restore procedures.
Acceptance Criteria
☑ backup-all.sh script performs WAL-safe SQLite backups (PostgreSQL, orchestra.db, neurowiki.db)
☑ Backup directory structure created (/data/backups/sqlite, /data/backups/config, /data/backups/neo4j)
☑ Tiered retention policy implemented (90d SQLite, 180d config, 30d Neo4j)
☑ S3 lifecycle rules configured via setup_s3_lifecycle.sh
☑ Automated backup integrity verification via verify_backup_integrity.sh
☑ Backup freshness monitoring via check_backup_freshness.sh and backup_alerts.sh
☑ Emergency restore runbook documented in docs/runbooks/emergency_restore.md
☑ Restore functionality tested via restore_database.sh
☑ Cron jobs configured via setup_backup_cron.sh for automated execution
☑ Backup status visible on /status page and /api/backup-status endpoint
Approach
Create backup-all.sh: Main backup script that:
- Performs WAL-safe SQLite backups using
.backup command
- Backs up config files (.env, nginx configs)
- Creates quick Neo4j tar backups
- Compresses all backups with gzip
- Applies tiered retention cleanup
- Syncs to S3
Verify existing scripts:
-
restore_database.sh - Database restore with safety checks
-
verify_backup_integrity.sh - Daily integrity verification
-
check_backup_freshness.sh - Freshness monitoring
-
backup_alerts.sh - Alerting system
-
neo4j_backup.sh - Crash-consistent Neo4j dumps
-
setup_s3_lifecycle.sh - S3 lifecycle configuration
-
docs/runbooks/emergency_restore.md - Runbook documentation
Create setup_backup_cron.sh: Cron setup script that schedules:
- Full backup cycle every 15 minutes
- Neo4j dump daily at 02:00 UTC
- Integrity verification daily at 03:00 UTC
- Backup alerts every 30 minutes
Verify API integration: Confirm /status page and /api/backup-status endpoint display backup informationTest backup workflow: Run backup-all.sh with --no-s3 flag to verify functionalityDependencies
Dependents
- All other tasks depend on reliable backups for data safety
