Hi @Евгений1310. let me see if I can help you out here.
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
If you have forgotten your pattern lock for your phone i would recommend you to perform a software repair using Xperia Companion and a computer. You can find a step by step guide here.
Do note that it is not possible to create a backup of your data as the phones memory is not available when the screen lock is active.
Let me know how it went!
