integration is enabled, such machines appear as unmanageable. A backup policy cannot be
applied to them.
Agent for Hyper-V
is installed on the host
You can choose between creating a virtual machine on the Hyper-V server and creating a
VMware Workstation, Microsoft Virtual PC or Parallels Workstation machine in the folder you
select.
Virtual machines created on the Hyper-V server as a result of backup, will not appear on the
management server, because such machines are not supposed to be backed up.
What is the host's processing power?
The conversion task will be created on the machine being backed up, and will use this machine's date
and time. In fact the task will be executed by the host that you select and so will take that host's CPU
resource. If multiple backup plans use the same host, multiple conversion tasks will be queued on
that host and it may take considerable time to complete them all.
What storage will be used for the virtual machines?
Network usage
As opposed to ordinary backups (TIB files), virtual machine files are transferred uncompressed
through the network. Therefore, using a SAN or a storage local to the host that performs conversion,
is the best choice from the network usage standpoint. A local disk is not an option though if the
conversion is performed by the same machine that is backed up. Using a NAS also makes good sense.
Disk space
On VMware ESX/ESXi, new machines are created with pre-allocated disks. This means that virtual
disk size is always equal to the original disk capacity. Assuming that the original disk size is 100 GB,
the corresponding virtual disk will occupy 100 GB even if the disk stores 10 GB of data.
Virtual machines created on a Hyper-V server or workstation type machines (VMware Workstation,
Microsoft Virtual PC or Parallels Workstation) use as much disk space as the original data occupies.
Since the space is not pre-allocated, the physical disk on which the virtual machine will run is
expected to have sufficient free space for the virtual disks to increase in size.

Recovering data
When it comes to data recovery, first consider the most functional method: connect the console to
the managed
machine running the operating system
and create the recovery task.
If the managed machine's
operating system fails to start
or you need to
recover data to bare metal
,
boot the machine from the bootable media (p. 371) or using Acronis Startup Recovery Manager (p.
53). Then, create a recovery task.
Acronis Universal Restore (p. 54) lets you recover and boot up
Windows on dissimilar hardware
or a
virtual machine.
A
Windows system can be brought online in seconds
while it is still being recovered. Using the
proprietary Acronis Active Restore (p. 56) technology, Acronis Backup & Recovery 10 will boot the
machine into the operating system found in the backup as if the system were on the physical disk.
The system becomes operational and ready to provide necessary services. Thus, the system
downtime will be minimal.
