So, we need more space on our devices. My goal was to increase our iCloud storage, move everything to iCloud that we want to keep and then delete them from our iPads.
After researching this topic, it sounds like deleting files from the iPad will also delete them from iCloud. We don't want to do this.
I also read that you can turn off Photos from your iPad, and then delete the photos you don't want from your iPad. Doing this will keep the photos on iCloud.
1) If we did turn off Photos on our iPad, delete the photos/videos we don't want and then turned Photos back on, would the Photos app try to resync with iCloud and therefore delete the photos on iCloud that had been deleted from the iPad? We would not want this to happen.
2) What is the best/safest/smartest way to backup files from your apple devices that you don't need to keep on your device?
Google photos - look into that.
