Does google drive work the same way as Dropbox? Cross platform, acts as a folder in your home dir, selective sync, etc? Seriously ready to move on from Dropbox and my google fiber account comes with a free terabyte of google drive.
The Windows and Mac clients create a folder in your home directory. There are ways to rename it, but essentially anything you put in the ~/Google Drive/ folder is synced just like Dropbox.
No native linux support is a bummer, but if you only need to use it there infrequently, the web client is quite capable for manual uploads and downloads.
