I'm currently working with mega, although having issues installing their desktop app
though I don't think it could provide an integrated cloud experience with kali

What cloud solution is best for kali?

I have a laptop and desktop kali and I'm looking for a seamless way to synchronize data between both.
I like the integrated dropbox folder accessible from a local explorer proposed by dropbox, although I have reserves about the company itself.

bonus points for
available storage, privacy, accessibility and ease of use.
