Rbrylawski and I are correct. iCloud is NOT a true data storage/archiving service.
I realise that 200 GBs of iCloud storage is cheaper per month than DropBox’s limited data subscription pricing plans, but iCloud isn't a permanent archiving solution, either.
You are saving money at the risk of losing, obviously important data.
You could consider supplementing your iCloud storage and use Google Drive/Photo data storage/backup storage.
While Google, like DropBox, doesn't have a variety of tiered storage size plans, they have, at least, a 100 GBs monthly storage plan for $1.99/month.
Coupled with Google's additional free tier of 15 GBs per month, that is 115 GBs of stored data for $1.99/month.
That is a pretty good pricing structure.
At least this will hold more than half your data safely and permanently without fear of removing or deleting data by accident, like when using iCloud.
AND with Google Drive/Photos, you CAN choose/decide what you want to store there.
iCloud is dangerous to use for any long term data storage as accidentally deleting important data can happen at any moment.
I only use the 50 GBs iCloud plan to backup things/data on my iPad that are only of small/medium importance to me, that I still do not really want to lose, but won't be a detriment or catastrophic to me if I accidentally lose some of this data.
I use Apple iCloud as my sole secondary data backup source, but do not sync any photos or any real important apps and other very important data to iCloud, at all!
