Implement enhanced crontab management system with automated backups and logging
- Added enhanced crontab entries with comprehensive logging to syslog. - Created a management script (`manage-enhanced-crontab.sh`) for installing and verifying crontab entries. - Introduced backup scripts for crontab management, including automated timestamped backups and cleanup. - Developed documentation for enhanced crontab and multi-system management. - Established a directory structure for managing crontab backups across multiple systems. - Implemented error handling and logging for backup operations. - Added health monitoring and reporting features for backup processes.
