Backing up Azure

Does anyone out there have any experience with backing up VMs and storage on Azure? We currently are storing long-term docs and files in Azure storage, and we have a few production and dev servers that we want to backup system state and files from. Would it be best practice/a good idea to check out the Azure Backup Vault solution, or not put all of our eggs in one basket and find something else? I really appreciate the input ahead of time.
