Most of us treat HMI backups as an afterthought—right up until the moment the industrial PC’s SSD dies at 2 AM on a holiday weekend. If your current MCGS (McgsPro or Embedded) backup routine is simply copying the .mcgs project file to a USB stick, you are not backed up. You are merely versioned.
Never overwrite a backup. Use filenames like MixerProject_v2.0_2025-03-15.mcgsx .
