I have been using optical media for backups since 1997. I started with 700 MB CDs and later upgraded to 4.7 GB DVD+R discs. My favorite brand is Verbatim (Media ID: MCC), and I use ASUS DVD burners.
I always burn two copies of each disc. In addition, I keep all the data on a hard drive for quick access and another copy on Google Drive in case of a local disaster.
I don’t rely solely on mechanical devices or electronics. Even when used properly, capacitors, motors, and NAND cells will eventually fail someday. Optical discs, however, can outlive me if they are stored correctly.
