# backingStoreType()

Returns the type of backing store you want for your screen saver’s window.

```
class func backingStoreType() -> NSWindow.BackingStoreType
```

## Discussion

This method returns <doc://com.apple.documentation/documentation/AppKit/NSWindow/BackingStoreType/buffered> by default. If you want to change the backing store type, override this method and return a new value. If you override the method, you don’t need to call the inherited version.
