How to backup photos to iCloud without deleting them from the iPhone?
My main method of backup is Google Photos and I do not plan to change that. I bough a subscription for iCloud as a secondary service to back up my photos and videos to.
Is there a way to backup photos to iCloud without deleting them from my iPhone? All the documentation I found online points me to the optimize storage option. This option doesn't seem to have a manual control and I'm afraid that iCloud will upload a photo and leave only a reduced file size copy on the phone before Google Photos backup picks it up. Is it possible to disable the optimize storage option? If yes, where do I need to go to do that?
If I manage to upload my photos from the phone to iCloud without deleting them at first, but come back and delete them later when my storage fills up, will that remove the photos from iCloud?
All these questions are coming from Google Photos allowing manual control of uploading and deleting the photos when my storage fills up. The app will guide you through how to make sure all your photos are backed up online before they are removed from the device. After you remove them from the device, they stay online, you can download them to the phone again, or via computer, delete them again, etc. You have a full manual control over your photos and videos, and nothing is removed unless you explicitly told the service to do so. I tried selecting the photos on my iPhone and manually pushing them to iCloud but seems like there is no such option, or I wasn't able to find it.
Just to clarify:
- I want to keep using Google Photos as my primary backup method, please do not suggest to stop using it and switch to iCloud exclusively.
 - I'm using a PC laptop so unfortunately iCloud allows me to only upload JPGs via the browser. Can I use any of the iCloud Windows apps to back up my photos and videos to iCloud Photos instead?
