MCGS HMI backup refers to the process of creating and storing duplicate copies of critical data, configurations, and programs associated with the MCGS HMI system. This backup data serves as a safeguard against potential losses or corruption of the primary data, allowing for swift recovery in the event of a system failure, hardware malfunction, or human error. A comprehensive MCGS HMI backup strategy involves regular data backups, secure storage, and a well-defined recovery plan.
Unlike cloud-based SCADA systems, most (such as the TPC series, 7072GT, or 1061Ti) store their runtime projects and recipe data on internal flash memory or removable SD cards. This makes them susceptible to:
: Maintain comprehensive documentation of the backup and recovery procedures. Ensure that personnel are trained on these procedures to facilitate quick and effective recovery in case of an emergency.
All plants using MCGS should adopt a formal backup policy based on the checklist in Section 10. Doing so ensures operational continuity and compliance.

Despite the low cost of external storage, many facilities perform ad-hoc backups or none at all. This paper aims to standardize the backup process for MCGS HMIs, covering both development environment (MCGS Embodied Development Software) and runtime environment (embedded HMI hardware).
