how to get backup Your iphone – Erasing and Restoring with iTunes
If you’ve forgotten your iPhone’s passcode, you can erase the phone’s data and passcode with iTunes, then restore using a backup.
Your passcode will be removed in the process, allowing you to set a new one.
You can also use Siri to get around the lock screen; please note that doing so on any iPhone other than your own can be illegal.
Also note that the Siri bypass only works on iOS 9, and is subject to change; as with any methods that allow you to bypass the passcode, this glitch is unintentional and thus liable to be fixed by Apple as soon as they recognize it.
