You can use the Metallic software to back up and restore VMware virtual machines that are hosted on a vCenter or a standalone ESX server. You can configure a hypervisor to represent a vCenter or a standalone ESX server.
Backups
Data You Can Back Up
Virtual machines (Windows and Linux, powered on or powered off)
VM templates (using HotAdd, NAS, NBD, or NBDSSL transport modes)
VMDK files
Virtual RDMs
GPT or dynamic disk volumes
vSphere tags on virtual machines
VM custom attributes
VM vApp options
Settings for Distributed Resource Scheduler (DRS)
Fault-tolerant virtual machines that meet the following requirements:
Configured as fault tolerant in the vSphere Web client
Hosted on ESX 6.x or a more recent version
VM hardware version 11 or a more recent version
Data You Cannot Back Up
Virtual machines that contain SCSI adapters that are configured for bus sharing (physical or virtual)
Virtual machines that are configured with fault tolerance (before ESX 6.x or hardware version 11)
Virtual machines that do not have a disk attached
Virtual machines replicated by VMware Site Recovery Manager (SRM)
VM templates (using SAN transport mode)
VM Settings for High Availability (HA)
Physical RDMs
Independent disks
Disks using the multi-writer option (install an in-guest agent on the VM to protect data on multi-writer disks)
Page and swap files (VMware Tools must be installed on guest VMs)
Backups You Can Perform
Full backups
Incremental backups
Synthetic full backups
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
Full virtual machines
Guest files and folders
Disk files
Attaching disks to an existing virtual machine
Virtual machine files
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
Destinations You Can Restore To
The current location (in place)
A different location (out of place)
A guest agent
A different hypervisor (cross-hypervisor restore)
