One thing you should absolutely not count on, but might be a course of actions for large clients, is to contact support and ask them to restore accidentally / maliciously deleted files.

I would never use this as part of the backup and restore plan; but I was lucky when a bunch of customer files were deleted due to a bug in a release. Something like 100k files were deleted from Google Storage without us having backup. In a panic we contact GCP. We were able to provide a list of all the file names from our logs. In the end, all but 6 files were recovered.

I think it took around 2-3 days to get all the files restored, which was still a big headache and impactful to people.

This is not a reliable mechanism btw. There will be times when they won't be able to restore the data for you. Their product has options to avoid this situation like object versioning.
