However, you still need to maintain the VM by performing tasks, such as configuring, patching, and installing the software that runs on it. Azure virtual machines can be used in various ways.

On-premises - Back up files, folders, system state using the Microsoft Azure Recovery Services (MARS) agent. Or use the DPM or Azure Backup Server (MABS) agent to protect on-premises VMs (Hyper-V and VMWare) and other on-premises workloads. Azure VMs - Back up entire Windows/Linux VMs (using backup extensions) or back up files, folders, and system state using the MARS agent. Azure Files shares - Back up.
