    Selectively delete file across all backups

    That's not possible from definition of the backup. Backup is backup state from past time, modyfiing backup = creating new backup from current time. Backup is read only. You never delete from backup. You delete backup usually via expiration parameters. GDPR has nothing to do with it.
