If a physical MMC fails due to electrical surges, age, or environmental degradation, a high-quality image backup allows maintenance teams to burn the image onto a replacement card. This restores production in minutes without needing the original TIA Portal or Step 7 source project. 2. Version Control and Cloning
Works with many generic internal or USB-attached SD/MMC card readers. Why "Extra Quality" Matters in Industrial Backups
