“UniSuper had backups in place with an additional service provider. These backups have minimised data loss, and significantly improved the ability of UniSuper and Google Cloud to complete the restoration.”

Again, the same quote I already quoted above, direct from UniSuper’s website. They needed to use their backups at a different cloud provider, as GCP’s data wasn’t recoverable. I don’t know why you’re arguing so strongly against this.

That they used external backups doesn't actually imply anything about the GCS backups being unavailable. And Google's press release explicitly notes that unisuper used both. (And there's all kinds of reasons to have used both, both good and bad)

Put formally, we have statements that

    - 1. A and B exist
    - 2. A was used
    - 3. A and B were used

Your conclusion from these statements is that, because (2) A was used, therefore B does not exist. Hopefully putting it like this makes it clear why I'm so confused.

I’ll concede my point, well argued.
