do you use syncing? because if so, then i thought this wasn't a good backup strategy?
for example, my photos could get deleted on my iphone accidentally and that change would sync with all my other devices and that data would be lost forever.
I guess that is a risk I'm accepting. For what it's worth, for photos specifically, Apple keeps them in a deleted folder for up to 30 days. But I'm pretty careful with my digital content and I would much rather them be synced.
