Restore Options for All Selected Items (General) - Attach Disks to an Existing Virtual Machine

Use this dialog box to control how disks from the source virtual machine will be attached to a target virtual machine. The following options are available when you are attaching disks to an existing virtual machine:

Destination client

Displays the name of the proxy computer that will be used to perform the restore operation. By default, the proxy computer that was used to back up the virtual machine is used for the restore.

vCenter

Displays the name of the vCenter where the disks will be restored. Click Change to restore to a different vCenter.

VM and Disk

This column displays the list of all virtual machines and disks selected for restore. Expand each virtual machine to view the disks in that virtual machine.

Restore to Existing VM

Click in this column and click ; then select the target virtual machine to which you want to attach all disks from the source virtual machine. By default, disks will be restored to the same virtual machine from which they were backed up.

Datastore

This column displays the datastore of each disk. To change the datastore of any disk, click in the corresponding row; then select a datastore from the list.

Virtual Machine Configuration

  • Unconditionally overwrite disks with the same name

    Select this option to overwrite an existing disk with the same name.

  • Disk Provisioning: Select a provisioning type:
    • Original (default): Use the same disk provisioning that the source virtual machine used at the time of backup.
    • Thick Lazy Zero: Use thick lazy zero provisioning to allocate disk space for all disks. This method only writes to sectors of the disk that contain data.
    • Thick Eager Zero: Use thick eager zero provisioning to allocate disk space for all disks. This method writes zeros to any unused sectors of the disk.
    • Thin: Thin provisioning allocates full size and commits only as much storage space as the disk needs for its initial operation.
  • Transport Mode: Select a transport mode:
    • Auto (default): The most suitable transport is selected automatically based on the setup.
    • SAN: For directly connected storage using Fibre Channel (FC) or Internet SCSI (iSCSI) protocols; only available if the proxy is on a physical machine.
    • Hot Add: Used when the Virtual Server Agent is installed on a virtual machine on an ESX server.
    • NBD: Data is transmitted over a TCP/IP connection between the ESX server and proxy.
    • NBD SSL: Uses the TCP/IP connection with encrypted data transfer.

Save As Script

Click to open the Save As Script dialog, which allows you to save this operation and the selected options as a script file (in XML format). The script can later be executed from the Command Line Interface using qoperation execute command.

When you save an operation as a script, each option in the dialog will have a corresponding XML parameter in the script file. When executing the script, you can modify the value for any of these XML parameters as per need.
