CA VM:Backup

CA VM:Backup is a utility for z/VM environments that provides backup and restore capabilities for CMS and non-CMS file systems, including Linux. It supports backing up CMS minidisks, SFS filepools, and Linux file systems. The HiDRO (High-speed Disaster Recovery Option) allows for standalone backup and restores when no operating system is operational, facilitating rapid recovery from system failures.

Key components include the backup engine, restore engine, and configuration file management system. These components communicate through internal APIs and system calls. Configuration is managed through configuration files that define backup schedules, retention policies, and target devices.

The system uses z/VM security mechanisms like RACF for authentication and access control. The architecture supports integration with z/VM's security framework and storage management systems. Administrators can use the command-line interface (CLI) and potentially a web-based console for managing backup jobs and monitoring status.

CA VM:Backup competes with other z/VM backup solutions by offering integrated features for both CMS and Linux environments, with HiDRO providing a distinct advantage for rapid disaster recovery. The architecture is designed for high performance and scalability within the z/VM environment.
