Welcome to Android Central! Did you already try Huawei's own backup service? https://consumer.huawei.com/us/support/backup/

To roll back to the previous Android version, I think you'd have to root the phone and flash the previous firmware. Not advisable for a non-technical person. Is there a reason you want to do this?
