Hello. I am assuming many of you guys keep backups of large amounts of data. What would you say is the best media to store data? Right now I have DVDs and an hard drive, neither of which I trust. DVDs have their problems and hard drives are known for failing at any moment. Is Blu-ray any good? It can store large amounts of data and apparently they cannot be scratched, which I doubt is true but anyway. Even if they are hardier than DVDs surely they can decompose like their lesser brethren right? You know, when oxygen enters the disc and rots the reflective material...
