One of the best Dropbox alternatives that most Linux users don’t know about is Zoho WorkDrive. It almost seemed too good to be true when I found it, but you get 1 TB of storage for only $2.50 per month.
They make a Linux desktop app that you can install on any Linux distro.
Everything is encrypted in transit and also encrypted on their servers.
I also use Zoho Mail because they have a nice mail app that comes as an AppImage for Linux and the feature set is quite nice.
They let you try out the cloud drive free for a few weeks, I believe. But it’s so cheap for that much storage, it was a no-brainer for me.
And you also get the Zoho office suite which is just as good as Google Docs.
