We have Dropbox for my Corp work stuff - anyone in the company can access it and I'm not the administrator, so I don't want my personal photos on it or any file or docs related to my other businesses.
I have Google drive that has 30 gigs of very private personal stuff, family photos etc. It also has notes to myself and files and docs related to my other businesses. I need to access this information both from my office computer and from my laptop at home. While Google says you can sync only specific folders to a computer, as soon as I fire it up it starts syncing all my photos onto my office computer - not good. Telling it to stop makes no difference, it just keeps syncing.
So I need a third cloud storage option. If I had one for the Corp, one for my other businesses, and one for private stuff I could feel more or less confident they would stay separate. I tried iCloud drive. It has some goofy restriction about uploading folders, you have to move one file at a time. That makes it a pain to migrate to.
Are there any other options? I'm looking to store and sync 2 or 3 gigs of mostly Word and Excel files.
