Once in a while, the topic of DVD backups arise in #ab. Earlier this week natsuneko [or nekosasu] mentioned backing up some 300GB onto DVD. All is good in the world, but DVD’s do get scratches and depending on the media, may start to lose data blocks after time. Is there anything that can be done to aid in preservation?
Yes, it’s called PAR2 (Parity Archiving).
