A disk backup created while executing a backup plan can be converted to a virtual machine immediately, on schedule, or combining both methods.
The conversion task will be created on the machine being backed up, and will use this machine's date and time. If the agent that backs up the machine is installed outside it (such is the case when a ESX(i) or Hyper-V virtual machine is backed up at a hypervisor level), the task will be created on the machine where the agent is.
The target virtual machine must be powered off by the time of conversion, otherwise the conversion task will fail. If this happens, you can restart the conversion task manually after powering off the machine. Any changes made to the machine while it was powered on, will be overwritten.
