The Dropbox app has a camera roll auto-upload feature. It's reliable, full-resolution image file backup and works for iOS and Android.

iCloud Photos is the worst: Last time I tried to download all my iCloud Photos/Videos (~1000) from the website it turned out to be impossible: You can download a few, but after 200 or so you just get server errors. And it always chokes on videos, stopping before having finished downloading the full file. There is no bulk export option like with Google Takeout.

Now I hear that this is not a problem if you have the Photos app on you Mac (it syncs), but I don't have a Mac.



One major flaw: Dropbox on iOS rotates the image data and resets the EXIF orientation header when it finds a rotated file. If you've ever used a different sync path you'll end up with a bunch of duplicate images with different hashes.


I have a lot of duplicate images from dropbox but I'd never known why until now. It just required me to get an additional app not by dropbox that evaluates images and deletes duplicates which took me a long time to find a good one as terrifying as that process is.


Which one did you use? I have had the same problem.


n.b. if anyone at Dropbox sees this or others want to reference it, here's the ticket: https://dropbox.zendesk.com/requests/3750448


That link doesn't work for me, says request not found.

Can you clarify this a bit? I.e what does the Dropbox app do if you take a picture in portrait mode, and what does iOS do? Is the rotation info lost completely?


Yes: it rotates the pixel data and resets the EXIF Orientation header. That means that it looks identical even when displayed as expected with a viewer which doesn't honor the EXIF orientation.

It's a lossless rotation - you can actually use something like jpegtran to rotate it back and the pixel checksum in ImageMagick's identify will match – but it completely breaks any system which uses checksums to detect duplicates, of course. I noticed when I started testing Google Photos and had a ton of duplicate images.

I know. I used to use it. It worked perfectly. I switched to Onedrive primarily because my free 48GB Dropbox expired and I got 100GB Onedrive with my new phone.
