Insync is an unofficial Google Drive client that "extends Drive's web functionality to your desktop by integrating tightly with Windows, Mac and Linux so you can get work done".
|Insync for Linux: Nautilus integration / Ubuntu appindicator|
Insync for Linux is out of beta and it now offers the same features available for the Windows and Mac clients:
- multiple account support
- selective sync (all files and folders)
- offline access to Google Docs
- symlink support
- built-in sharing (without using a web browser)
- file manager integration
- recent changes
The Linux version also comes with a feature that allows you to add any folder on your system to Insync via the file manager context menu (using a symbolic link).
Insync was free to use while in beta only so to use the latest stable release you must pay a one-time fee of $9.99 per Google account (which includes unlimited installs across all desktops). You can try the stable release for free for 15 days. The trial period can be extended by 15 days if you refer a friend (both you and your friend get an extra 15 days).
The tool supports Ubuntu, Debian, Linu Mint, PCLinuxOS, MEPIS and Fedora with the following desktop environments: Unity, Cinnamon, GNOME Shell, KDE, LXDE, Xfce, MATE and Openbox + fbpanel and 5 file managers: Nautilus, Nemo, Caja, Dolphin and Thunar.

* The installer will try to detect your desktop environment and install the package required for file manager integration. If you change the desktop environment or use a different file manager, you'll have to install the file manager integration package from the repositories (the Insync repository is added automatically): simply search for Insync in Ubuntu Software Center, Synaptic, etc. and install the package for your file manager, like insync-thunar, insync-nemo, insync-nautilus and so on.
