dead phone / backup transfer

Hello, I had an xperia z5 that i dropped and the screen shattered. I think some water got in because no one seems to be able to fix it. I bought a new phone (huawei), my question is if it’s possible to transfer the backup of the Z5 that i have on my pc to the new phone.. I can’t seem to find any way of doing that, i’ve lost all my contacts/files and so on, so any help is greatly appreciated. Thank you.
