This would be the poster child for durable backups such as Microsoft Silica (if Microsoft dared to piss off those plaintiffs).

At 99 Petabytes, an offline copy would take about 2,000 LTO-9 tapes. I'm not familiar with other vendors, but a single IBM TS4500 tape library offers about 400 PB of near-line storage and I don't think IBM would be making the largest ones in existence.

Also, CERN could host multiple copies on unused blocks of their storage farm.

edit: just found a StorageTek (now Oracle) that can do "57.6 EB of uncompressed data". That's just surreal. HPE sells a much more modest unit that can store 2.5 EB.
