Not sure why are you being downvoted. That was actually the first thing I thought - what is the backup strategy? Mirroring is for performance + service continuity. Let me remind that there already was a fire that destroyed some equipment for internet archive but luckily not digitalized data: https://www.theverge.com/2013/11/7/5076166/the-internet-archive-seeks-donations-after-fire-destroys-equipment https://www.theverge.com/2013/11/7/5076166/the-internet-arch... Luckily that article from 2013 mentions: > None of the Internet Archive's digitized data was lost in the fire as backups are held in multiple locations.
