## Automation and Scheduling
### Performance Tuning
### Cron Integration
- **Parallel verification:** Enabled by default for faster operations
- **Performance monitoring:** JSON-based metrics collection
- **Automatic cleanup:** Configurable retention policies
Example crontab entries for automated operations:
## 📊 Monitoring & Alerting
```bash
# Daily Plex backup at 04:15
15 4 * * * /home/acedanger/shell/plex/backup-plex.sh --non-interactive --auto-repair 2>&1 | logger -t plex-backup -p user.info
### Health Checks
# Daily validation at 07:00
0 7 * * * /home/acedanger/shell/plex/validate-plex-backups.sh --fix 2>&1 | logger -t plex-validation -p user.info
```
The monitoring system tracks:
### Log Monitoring
- Backup success/failure rates
- Database integrity status
- Service uptime and performance
- Disk space utilization
- Recovery operation success
Monitor backup operations with:
### Performance Metrics
```bash
# Real-time monitoring
sudo journalctl -f -t plex-backup -t plex-validation
- Backup duration and size trends
- Database operation performance
- Service start/stop times
- Recovery operation benchmarks
# Historical analysis
sudo journalctl --since '24 hours ago' -t plex-backup
## 🚨 Emergency Procedures
# Performance analysis
jq '.[] | select(.operation == "backup") | .duration_seconds' logs/plex-backup-performance.json
```
### Database Corruption
## Troubleshooting
1. **First Response:** Run `backup-plex.sh --check-integrity`
2. **Gentle Recovery:** Try `recover-plex-database.sh --gentle`
3. **Advanced Recovery:** Use `icu-aware-recovery.sh` for Unicode issues
4. **Last Resort:** Execute `nuclear-plex-recovery.sh` with known good backup
5. **Validation:** Always run `validate-plex-recovery.sh` after recovery
### Common Issues
### Service Issues
1. **Database corruption**: Use `--auto-repair` flag or manual repair
2. **Insufficient disk space**: Check space requirements (2x backup size)
3. **Service management**: Ensure Plex service accessibility
4. **Archive validation**: Use validation script for integrity checks
1. **Check Status:** `./plex.sh status`
2. **Restart Service:** `./plex.sh restart`
3. **Monitor Logs:** Check system logs and script logs
4. **Validate Database:** Run integrity checks if service fails to start

- **[plex-management.md](./plex-management.md)**: Plex management and administration guide
### Integration Notes
- All scripts follow repository coding standards
- Consistent logging and error handling
- Color-coded output for readability
- Comprehensive help systems
## Migration Notes
When migrating from legacy backup scripts:
1. **Backup current configuration**: Save any custom modifications
2. **Test new scripts**: Run with `--check-integrity` first
3. **Update automation**: Modify cron jobs to use new options
4. **Monitor performance**: Check performance logs for optimization
The enhanced scripts maintain backward compatibility while adding significant new capabilities.

# ⚠️ WARNING: This script will completely replace existing databases!
# All data since the backup was created will be lost.
# Use only when standard repair methods have failed.
#
# Features:
# - Complete database replacement from backups
# - Automatic backup of current (corrupted) databases
# - Service management and safety checks
# - Comprehensive logging of all operations
# - Rollback capability if replacement fails
# - Verification of restored database integrity
#
# Related Scripts:
# - backup-plex.sh: Creates backups used by this recovery script
# - icu-aware-recovery.sh: ICU-specific recovery methods
# - restore-plex.sh: Standard restoration procedures
# - validate-plex-recovery.sh: Validates recovery results
# - plex.sh: General Plex service management
#
# Usage:
# ./nuclear-plex-recovery.sh # Interactive recovery
# ./nuclear-plex-recovery.sh --auto # Automated recovery
# ./nuclear-plex-recovery.sh --dry-run # Show what would be done
# ./nuclear-plex-recovery.sh --verify-only # Verify backup integrity
#
# Dependencies:
# - Valid Plex backup files
# - sqlite3 or Plex SQLite binary
# - systemctl (for service management)
# - tar (for backup extraction)

# Advanced Plex Database Recovery Script
################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Advanced database recovery script with multiple repair strategies
# for corrupted Plex databases. Implements progressive recovery
# techniques from gentle repairs to aggressive reconstruction
# methods, with comprehensive logging and rollback capabilities.
#
# Features:
# - Progressive recovery strategy (gentle to aggressive)
# - Multiple repair techniques (VACUUM, dump/restore, rebuild)
# - Automatic backup before any recovery attempts
# - Database integrity verification at each step
# - Rollback capability if recovery fails
# - Dry-run mode for safe testing
# - Comprehensive logging and reporting
#
# Related Scripts:
# - backup-plex.sh: Creates backups for recovery scenarios
# - icu-aware-recovery.sh: ICU-specific recovery methods
# - nuclear-plex-recovery.sh: Last-resort complete replacement
# - validate-plex-recovery.sh: Validates recovery results
# - restore-plex.sh: Standard restoration from backups
# - plex.sh: General Plex service management
#
# Usage:
# ./recover-plex-database.sh # Interactive recovery
# ./recover-plex-database.sh --auto # Automated recovery
# ./recover-plex-database.sh --dry-run # Show recovery plan
# ./recover-plex-database.sh --gentle # Gentle repair only
# ./recover-plex-database.sh --aggressive # Aggressive repair methods
#
# Dependencies:
# - sqlite3 or Plex SQLite binary
# - systemctl (for service management)
# - Sufficient disk space for backups and temp files
#
# Exit Codes:
# 0 - Recovery successful
# 1 - General error
# 2 - Database corruption beyond repair
# 3 - Service management failure
# 4 - Insufficient disk space
# 5 - Recovery partially successful (manual intervention needed)

# Description: Automated testing framework for the complete Plex backup
# ecosystem, providing unit tests, integration tests, and
# end-to-end validation of all backup operations.
#
# Features:
# - Unit testing for individual backup components
# - Integration testing for full backup workflows
# - Database integrity test scenarios
# - Service management testing
# - Performance benchmarking
# - Error condition simulation and recovery testing
# - Test result reporting and analysis
#
# Related Scripts:
# - backup-plex.sh: Primary script under test
# - restore-plex.sh: Restoration testing component
# - validate-plex-backups.sh: Validation testing
# - monitor-plex-backup.sh: Monitoring system testing
# - plex.sh: Service management testing
#
# Usage:
# ./test-plex-backup.sh # Run full test suite
# ./test-plex-backup.sh --unit # Unit tests only
# ./test-plex-backup.sh --integration # Integration tests only
# ./test-plex-backup.sh --quick # Quick smoke tests
# ./test-plex-backup.sh --cleanup # Clean up test artifacts
#
# Dependencies:
# - All Plex backup scripts in this directory
# - sqlite3 or Plex SQLite binary
# - jq (for JSON processing)
# - tar (for archive operations)
# - systemctl (for service testing)
#
# Exit Codes:
# 0 - All tests passed
# 1 - General error
# 2 - Test failures detected
# 3 - Missing dependencies
# 4 - Test setup failure

################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Comprehensive backup validation system that verifies archive
# integrity, database health, and backup completeness with
# automated repair capabilities and detailed reporting.
#
# Features:
# - Archive integrity verification (checksum validation)
# - Database integrity checking within backups
# - Backup completeness validation
# - Automated repair suggestions and fixes
# - Historical backup analysis
# - Performance metrics and reporting
# - Email and webhook notifications
#
# Related Scripts:
# - backup-plex.sh: Creates backups validated by this script
# - restore-plex.sh: Uses validation results for safe restoration
# - monitor-plex-backup.sh: Real-time system monitoring
# - test-plex-backup.sh: Automated testing framework
# - plex.sh: General Plex service management
#
# Usage:
# ./validate-plex-backups.sh # Validate all backups
# ./validate-plex-backups.sh --fix # Validate and fix issues
# ./validate-plex-backups.sh --report # Generate detailed report
# ./validate-plex-backups.sh --latest # Validate only latest backup
#
# Dependencies:
# - tar (for archive extraction and validation)
# - sqlite3 or Plex SQLite (for database validation)
# - jq (for JSON processing)
# - curl (for webhook notifications)
#
# Exit Codes:
# 0 - Success, all backups valid
# 1 - General error

# Plex Recovery Validation Script
################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Comprehensive validation script that verifies the success of
# Plex database recovery operations. Performs extensive checks
# on database integrity, service functionality, and system health
# to ensure complete recovery and operational readiness.
#
# Features:
# - Database integrity verification
# - Service functionality testing
# - Library accessibility checks
# - Performance validation
# - Web interface connectivity testing
# - Comprehensive recovery reporting
# - Post-recovery optimization suggestions
#
# Related Scripts:
# - recover-plex-database.sh: Primary recovery script validated by this tool
# - icu-aware-recovery.sh: ICU recovery validation
# - nuclear-plex-recovery.sh: Nuclear recovery validation
# - backup-plex.sh: Backup system that enables recovery
# - validate-plex-backups.sh: Backup validation tools
# - plex.sh: General Plex service management
#
# Usage:
# ./validate-plex-recovery.sh # Full validation suite
# ./validate-plex-recovery.sh --quick # Quick validation checks
# ./validate-plex-recovery.sh --detailed # Detailed analysis and reporting
# ./validate-plex-recovery.sh --performance # Performance validation only
#
# Dependencies:
# - sqlite3 or Plex SQLite binary
# - curl (for web interface testing)
# - systemctl (for service status checks)
# - Plex Media Server
#
# Exit Codes:
# 0 - Recovery validation successful
# 1 - General error
# 2 - Database validation failures
# 3 - Service functionality issues
# 4 - Performance concerns detected
# 5 - Partial recovery (requires attention)
