+### Protect your state from failures using `rollback`
+
+Sometimes stores may fail and you want your data back. In these cases, you'll need
+a rollback mechanism. When a store says it needs to be rolled back, **every sibling
+store on same dispatcher will be warned about it**.
+
+```javascript
+  ...
+  todos: [],
+
+  initialize: function (url) {
+    var self = this;
+
+    this.rollback(function () {
+      // bring old todos back, also it will tell another stores
+      // to be rolled back.
+      self.todos = self.oldTodos.slice(0);
+    });
+  },
+
+  addTodo: function (data) {
+    // Let's backup the data
+    self.oldTodos = self.todos.slice(0);
+
+    // Now apply the view
+    self.todos.push({text: data});
+    self.emitChange();
+
+    // Now try to react to the server
+    $.post('/todos', {text: data}, function (response) {
+      if (response.status === false) {
+        // if something goes wrong with the server, emit rollback.
+        self.emitRollback();
