It does not backup photo correctly

I rely on this app to backup all my iPhone photos automatically. Everything works fine if you never need to restore from iPhone backups. (When you get a new iPhone, repair/replace iPhone). Once you restore from iPhone backup onedrive will treat all your photos new and re-sync to onedrive again! Creating duplicate copies and use all your storage space. I have to restore two times last year due to phone upgrade & repair, now there are three copies of 32gb photos on my onedrive. Very frustrating, since this is the basic feature and selling point of this app.
