How do megasites like Youtube perform backups? According to https://www.quora.com/Where-does-YouTube-store-so-many-videos, 2014 they stored 76 PB every year, a number that most certainly has increased a lot since then. Is it even possible to backup this or do they solve the problems backups usually are used for in some other way (such as so much redundancy that it simply can't fail)?
