The links you posted say it was local files that had not been synced to Google Drive, so it's however long people were creating files that weren't synced to the cloud without the user noticing.
Does anyone have any technical insights as to what happened here? Was it related to Google's new account deletion policy or something totally separate?
I wonder if there is any correlation to the files deleted and the user accounts that were pruned--basically the file was deleted because you shared it with a user account that was pruned
Thanks! In regards to API quotas, the rate limiting happens on a per-user basis so we manage to stay away from the limits for most users. That being said, I did build the system with a retry mechanism with delays so in case something does hit a limit, it shouldn't be lost.
