That was well dealt with. Especially the part about deleting all long-press recordings from the servers. Very thorough Google!

Hmm, not really. If they know it's from a long-press, at least the activity website should say so, and not from "hotword activation".

But otherwise, yes, this is stellar. Also, hardware is hard.

What about deleting everything from backups? Will they spend time to search all of the backups they have and delete that data? Is the data really deleted or just marked as deleted so it's not shown on the website?

They don't need to search backups manually. All products are required to have automated pipelines (along with monitoring) to wipe out user data.

Any source on that?

There's an example of the Music pipeline going wrong:

Another reference for Fi: https://www.linkedin.com/in/pliu1/ "Redesigned and refactored the Fi user data deletion system to ensure compliance with data deletion policy, to add instrumentation, and to improve performance"

There is a dedicated team that tracks compliance for all products. (source: I was at Google)

Not only that did they destroy the data on the disk or only delete the named links to the data.
