Google Cloud accidentally wiped an Australian super[annuation] (pension) fund's entire cloud deployment earlier this year. I think that if you really want durable backups, they have to be reducible to object storage and put in someone else's cloud.
... not quite. I worked directly with the folks involved on getting more RCA details public. This customer used a single product on GCP, a specific type of VMware hosting, and the "subscription" to that product failed, which turned those resources off. It's more like turning off all their VM's, rather than deleting their entire account, identities, access structures, etc.
Thank you to share that blog post. That blog post specifically mentioned that no data was lost. I am confused by your comment about durable backups. Deeper question: Do people think on-prem backups are more reliable than cloud? I would say for 95% of orgs: no.
