I chose pCloud as my provider of choice. It's not unlimited, but it's $10/mo for 2 TB of storage and 2 TB of traffic. That is more than enough for most users, and you can increase the size in 2 TB increments at additional cost. pCloud has pretty much all the bells and whistles one would need. I certainly consider it rich in features. I also like that it can be used as a sync storage or just as a "hard drive in the cloud" where I don't have to keep the data or folder structure on my machine if I don't want to. The only downside is that the integrated encryption is an additional charge. To get around that, I decided to go with Boxcryptor, which I already had. The average user can use the free version of Boxcryptor. It is awesome and I highly recommend it. Both pCloud and Boxcryptor show up as physical drives on your computer, which I find convenient. So I have my primary source drive synced with the Boxcryptor drive/location and Boxcryptor is set up on my machine to encrypt the data on the fly as it is copied (surprisingly, this is not the default setting). Then, I have a separate process that syncs the raw Boxcryptor directory where the files show in their encrypted format (the "drive" version shows them unencrypted because everything is done on the fly both ways) to my pCloud storage. In the end, I have 3 versions - the unencrypted source, the encrypted Boxcryptor copy, and the pCloud backup which contains the encrypted copy.
