I need to archive 10PB of scientific data. Aerospace stuff. Anyone here have any thoughts on managing this kind of scale? Notes below:

• Format is just generic blob or file
• Ideally not tape or disc drives
• Archive/Cold tier, but will get accessed occasionally
• Need a way to backup or RAID

So far I’m coming back with a $150k budget requirement to purchase a boatload of 20TB storage drives, and that’s before backup/RAID. Cloud cost is something like $15k/mo, so it’s commensurate. Seems to me there’s got to be a better way to do this.

Any crazy ideas?

** Edit **

Appreciate all the responses already. Just to clarify, there will be professional advisors involved and I’m not betting the farm off of a Reddit thread. I’m just curious if anyone here has crazy ideas that the pros might not have top of mind, or if nothing else maybe someone has a cool annecdote to share that make for a neat thread.
