Unbacked up google photos

Do google get your unbacked up photos saved to their server, cause google works like gallery (show your device gallery photos in google photos, but you need to back them up, if you want to view them from every device)

Hi,

Usually, Google drives automatically backups your gallery data. It doesn't require any action from your side; the images are automatically backed up. In case you don't want your files to be saved in Google Drive, then you can open Google Drive and just delete the desired files from there.
