I need to back up 200TB to the cloud from a Nas, after looking at prices with Backblaze, Wasabi and Amazon. Seems that glaciar deep long term is what I'm thinking. Upload and forget it. $1 a Tb per month. Before I share this to my boss.

Anything else I should know? I'm familiar with the recover, egress fees.

I signed up for a free AWS trial but the interface doesn't seem so straight forward. Ideally I would like to have a drive mount on windows and use freefilesync to start the transfer. And drawback using this method?

Would I need to hire and technician do come in and do all the coding I see from watching the videos?

I personally have backblaze at home and I just have the simple icon on my task and a GUI interface and let it run.
