You can use the Metallic software to back up and restore VMs that are hosted on a Hyper-V cluster or a standalone Hyper-V server. You can configure a hypervisor to represent a Hyper-V cluster, a Hyper-V server in a cluster, or a standalone Hyper-V server.
Backups
Data You Can Back Up
Hyper-V VMs (powered on or powered off)
VHD and VHDX files
Snapshot files
Configuration files for the VMs
Metadata required for granular recovery of files (NTFS and ext3 volumes only)
VHDX formatted hard disks with sector size of 4K bytes without metadata
Hyper-V replica VMs that are stopped
Data You Cannot Back Up
Pass-through disks
Hard links (only for disk-level backup)
Virtual machine smart paging files
Certain virtual machines in which Volume Shadow Copy Service (VSS) fails to create a shadow
Devices residing in a guest virtual machine over iSCSI or vHBA
Hyper-V replica VMs that are running
Page and swap files (Hyper-V Integration Services must be installed on guest VMs)
VM folders with compression enabled
When a virtual machine resides on a VM folder that has compression enabled, backups of that virtual machine fail. However, manual snapshots of the virtual machine complete.
Backups You Can Perform
Full backups
Incremental backups
Synthetic full backups
Streaming backups
IntelliSnap backups
Backup copy
When You Can Perform Backups
On a schedule: The server plan that you assign manages scheduled backups
On demand: You can perform on-demand backups at any time
Restores
Restores You Can Perform
Guest files and folders
Full virtual machines
Disk files
Live Recovery
Backups You Can Use for Restores
The most recent backup: For example, restore the most recent backup to its original location
A backup from a specific date: For example, restore data to a point in time before it became unusable
Backups from a date range: For example, restore data that was accidentally deleted
