The Flash VM Boot feature allows you to run (boot) VMware and Hyper-V VMs directly from compressed and deduplicated VM backups, without recovering entire VMs first. When you boot a VM from a backup, NAKIVO Backup & Replication creates a new VM on the target server.
When the VMware VM is created, NAKIVO Backup & Replication takes a snapshot of the VM: this way all changes that occur to the VM are temporarily stored in the snapshot and discarded when you stop the job. When the Hyper-V VM is created, the application temporarily stores the changes to the VM in a disk-based write cache in the Backup Repository; changes are discarded when the job is stopped.
