Nice! I always love to see ‘hacked’, simple elegant solutions to problems like this (using a Raspberry Pi with an external SSD and some out-of-the-box software) vs. over-engineering something.

I am a little curious how the data replication actually works (and if it’s comprehensive replication of all iCloud data - how does the Photos app replication work specifically?), since one of the most convenient features of iCloud is the asynchronous media replication of your photos and videos.

Maybe that’s too nitpicky, but this seems to work great for your actual iCloud Drive files. Great work, Navid!
