Cloud sync services fully compatible with linux?

vendredi 22 juillet 2016

Hello all,
I wanted to hear what is your opinion on the best cloud services out there, that are fully compatible with Linux (and windows), offer enough storage space (eventually with a reasonable yearly fee) and offer good guarantee of safety when it comes to privacy.

I've used dropbox for some years, but 2gb is very little, and the security does not look top. I'm using box.com, where I have 50gb due to an old offer, but it does not work on Linux.
I was reading about alternatives such as Mega, which offer 50gb, but not sure it's very safe. Spideroak is well known, but only free trial.
Any experience/suggestions?
