On iOS, if I delete a backup will I still have all of my photos, even on my photo stream? I would like to know as my iCloud storage is running out so I want to get rid of my old backup and make a new backup. I really want to keep all of my photos and memories on my phone. Thanks
If you use Photo Stream as you mentioned your photos will be stored in iCloud separately and not in a backup, therefore it is safe to delete previous backups.
To further reduce backup size iPhone backup takes too much space
