Thanks for replying so quickly LACAllen!
I have been under the illusion that i-Cloud STORED my photos forever, which is why I pay extra storage monthly, but I may have already lost some!
Now, I cannot see the sense in paying extra for storage when it cannot keep more than the storage on my phone...Am I correct? Perhaps i-Cloud Storage is helpful if I just back up my Mac photos directly, provided I do NOT sync my i-phone to i-Cloud and ONLY sync my i-phone to my Mac?
(My Mac is backing up to Google Photos automatically, thank goodness).
I have had photos uploading automatically (I think this is what is meant by 'synced'?) to my Mac, which has been helpful: However, despite the latest photos on my phone currently visible on my Mac, the phone says "Upload Paused for 101 items...Not Enough i-Phone storage"...?! (My phone does not appear in i-Tunes when I connect it to the Mac, so maybe that has something to do with it?) Does that mean they are wirelessly going to my Mac but not to i-Cloud from my phone? (I am bewildered how I can check the photos on i-Cloud from my Mac anyway...?!)
Do I need to stop that somehow, and never sync my phone to my Mac again...? But SEPARATELY back up my phone using the 'Google Photos App' (which cannot load on my phone because I don't have enough room!!)
If I don't stop 'syncing' from phone to Mac, and I delete all photos off my phone, what do I have to do first, to avoid losing them off ALL SYNCED DEVICES (ie my Mac and i-Cloud Library!)?
I may have some of this wrong but, if I understand you correctly, to free up space on my phone now, can I still have the phone's photos 'synced' to my Mac and NOT to i-Cloud, as long as I have my Mac backing up to i-Cloud (and also Google Photos)? If so, how?
Do i-Cloud and Google Photos recognise duplicates (even if I have changed the name on one of them?)?
I don't really want to have to back up the photos manually (on external hard drive and/or Google Photos), although I do irregularly back up onto an external hard drive.
As you can see I am desperately in need of wise Help! ;). I just hope you understand what I am asking...?
Thanks :)
