AutoSave: the save Unity still does not do for you

The small Auto Save window: Save in 40, a tick to also back up the open scenes, and three buttons, Save, Cancel and Settings

Unity still does not save your scenes by itself. This tool does: every five minutes, a small window counts down in a corner, then saves everything.

  • Save, Cancel, or let it count. A Ctrl + S during the countdown closes it.
  • Silent when nothing changed, in play mode, during a build or a compilation, and when Unity is not the window in front.

The save itself is two lines:

EditorSceneManager.SaveOpenScenes();
AssetDatabase.SaveAssets();

A dated backup of every open scene​

Each save also copies every open scene into a folder named after the date and the time, outside the project: Unity never imports the copies, and they never end up in a commit.

A level broken on Tuesday? Tuesday morning's scene is one folder away.

The AutoSave folder: one folder per save, named with its date and time, and inside the three scenes that were open

Options​

The AutoSave page of the Project Settings: enable, time between two saves, logging, ask before save, popup delay, backup of the open scenes and its folder

In Project Settings > Unity Essentials > AutoSave: the time between two saves (5 minutes by default), the length of the countdown or "ask before save", and the backup folder.

Part of Unity Essentials, the toolbox of the Kugle Corp games. It started from Tarodev's Unity-AutoSave, a few open-source lines that save on a timer; the countdown window, the checks, the backups and the settings were added on top.
