   This is why you never ever use any optical media for backups. Despite the outer edge looking awful, it read without errors. What failed to read at all is around ~300MB of data 2/3 into the disk. There are no scratches or physical damage there, the actual media layer just failed or delaminated enough for it to be unreadable.
   
   Anybody that tells you optical media for backups is fine is simply wrong. It does not matter if it's a Blu-Ray, DVD, CD or Mdisc with its arbitrary marketing claims. I don't care if you spread parity data all over the disc, it fixes nothing. It's just a big cope. Use real archival storage like multiple tapes or even better a 24/7 disk array with redundancy and automatic scrubs.
