Properly Archiving Data to Optical Media: Multipar & TeraCopy Tutorial

If you’re just dragging digital data files onto a disc and hitting “burn,” your backups are rotting away. Stop doing this. I’ve been doing this wrong for over 20 years and I’m a professional multimedia producer! In this video, I expose the critical step most people skip when burning Blu-ray (BD-R) and DVD-R discs. If you aren’t using MultiPar to create parity data, you’re basically guaranteeing your files will be corrupted by bit-rot or physical scratches. It's all about that Reed-Solomon Error Correction Code (ECC), baby! I show you exactly how to calculate your block size, create the redundant files and force them to the outer edge of the disc where they can actually save your data when (not if) the disc gets scratched. Don't let your backups die.
