Quotiperius backup hyperv11/27/2023 Passthrough allows the virtual machine to directly access the storage device and doesn't store virtual volume data in a VHD file. Use guest-level backup if you want to protect data stored on passthrough disks. For example, to recover specific SharePoint items from a backed-up VM, you should do guest-level backup of that VM. At host-level you can recover an entire VM or specific files, but it won't provide recovery in the context of a specific application. This backup is useful if you want to protect specific workloads running on a virtual machine. If you deploy host level backup, you can recover an entire virtual machine, or files and folders (item-level recovery). These backups are flexible because they work regardless of the type of OS running on the guest machines and don't require the installation of the MABS protection agent on each VM. At the guest level, the agent is installed on each virtual machine and protects the workload present on that machine.īoth methods have pros and cons: Host-level backups At the host level, the MABS protection agent is installed on the Hyper-V host server or cluster and protects the entire VMs and data files running on that host. MABS can do a host or guest-level backup of Hyper-V VMs. The MABS protection agent is installed on each cluster node. Virtual machines in a cluster with CSV storage - Back up virtual machines hosted on a Hyper-V cluster with Cluster Shared Volume (CSV) storage. The MABS protection agent must be installed on all hosts. For example: a hard drive, a storage area network (SAN) device, or a network attached storage (NAS) device. Virtual machines with local or direct storage - Back up virtual machines hosted on Hyper-V host standalone servers that have local or directly attached storage. MABS can back up virtual machines running on Hyper-V host servers in the following scenarios: This article describes how to back up and restore Hyper-V virtual machines using Microsoft Azure Backup Server (MABS).
