| Component | Recommendation | |-----------|----------------| | | Minimum 1 GB for bootable environment, but 2 GB+ is better. | | USB Port | Use USB 3.0 if available; USB 2.0 will be very slow for large images. | | Destination Drive | Never save the backup to the same physical drive you are imaging. Use an external USB HDD/SSD or network location. | | Backup Mode | Choose “Sector-by-sector” only if you suspect file system corruption. Otherwise, “Standard” is faster. | | Compression | Set to “Normal” to balance speed and space on older CPUs. |
