In my attempts to use Google Drive for some automated important data backups, I'm making use of the API and a Service Account to upload data to a Team Drive. The account only has 'Contributor' access to this drive, and thus can only 'Add' or 'Edit' files.
However, Google states it may delete historical revisions after 100 revisions - Leading me to think some malicious agent could simply edit the file 100 times to effectively 'delete' the contents practically instantly.
Is this the case? If so, would I be able to restore the deleted revisions through the Google Admin panel like normally permanently deleted items? Can Google Vault save me from this? Is there another way around this?
