This is a most excellent place for technology news and articles.
I used iCloud Drive for a while since it was a two-fer with iPhone backups and end-to-end encryption.
But for some reason the Windows Store client is garbage. I've done the reinstall, etc. dance but it keeps hanging while attempting to sync and ballooning logs to hundreds of MB.
So I have no cloud storage. I instead just plug in my phone to iTunes for it's periodic local backup and drag-and-drop whatever files I want to have on my phone then.
I use my Synology NAS, which then backs up the most important stuff to Synology C2, and a redundant copy of all my photos and things from my Apple devices in iCloud. Apple One Premier comes with 2Tb, and I don’t use Apple One for the cloud storage. So it’s a bonus backup.
My family and I use iCloud. It’s $30 a month for 2TB of storage, Apple Music, fitness, and news. Also has private relay for protecting our devices, hide my email for generating temporary emails (LOVE this feature) and it automatically backs up all our devices to the cloud and it’s easy to store and share files from it. And it has all of apples privacy and security measures behind it. The only downside is if you forget your passwords and recovery keys apple can’t retrieve your data for you, and obviously you need to have a few apple devices for it to be completely useful. Being able to snap photos on any device and have them all synced together and also backed up is key for me, personally my photos are my most priceless data of all.
