How does this compare technically to iCloud[1] and (lesser known) Upthere[2]? And any other cloud storage providers that treat local files as purgeable / do selective syncing.<p>For example one major difference I've noticed is iCloud can sync while asleep (Power Nap). This has proven to be <i>very</i> useful with my iCloud Photo Library, which has tons of syncing to do every day and night over a slow connection.<p>Another distinction with Apple's approach, maybe not directly comparable to Dropbox Business, is how it is integrated with apps. I mentioned photos, but it also covers iTunes music and movies/TV. It lets it be smarter than a purely filesystem level sync, like downloading photo previews and purging movies only after you've watched them. In other words it has a direct Dropbox competitor in iCloud Drive, but also adds domain-specific syncing.<p>Are there any advantages to Dropbox's approach?<p>[1] <a href="https://support.apple.com/en-us/HT206996" rel="nofollow">https://support.apple.com/en-us/HT206996</a><p>[2] <a href="https://upthere.com/technology" rel="nofollow">https://upthere.com/technology</a>
