On-premises workloads can be secured using Microsoft Azure Recovery Services (MARS) agent, Azure backup server (MABS), or by interaction with System Center Data Protection Manager while VMs and the workloads housed in those VMs are backed up using a backup extension (DPM). For Linux VM backups, Azure Backup supports the list of Linux distributions endorsed by Azure. Its primary drawback is the need for an extra step during backup and restore as well as for additional local disk space. If Backup can't take an app-consistent snapshot, then it takes a file-consistent snapshot of the underlying storage (because no application writes occur while the VM is stopped).
