I learned my lessons with Dropbox, but couldn't find anything as "simple", secure with the bonus of being Canadian. So I eventually found and switched to SpiderOak but the speeds and Mac client are truly terrible, even at the end of 2016 and start of 2017. I couldn't even complete half a backup. Small files are fine but large files were impossible.

Switched to Sync.com a Toronto based company, with only Canadian servers. That means a lot to me as I've tried to remove myself from storing on American servers (just out of good practice on my part), and the service and support has been spectacular. I tried other options as well and this won me over.
