Of all the things Coinbase could spend money on, backups may be the smartest! Imagine if they lost a few billion dollars worth of crypto to a faulty SSD or something!
>I know that Coinbase used to spend $35,000 a month to back up the data directory of ETH nodes.
They paid backups to whom? Who was vendor....I'm interested.
Amazon. They put it on an EBS volume and kept it around.
