Virtual machine restore

Phoenix Editions: File:/tick.png Business File:/cross.png Enterprise File:/tick.png Elite

Phoenix lets you restore your virtual machines to a Hyper-V host that is registered with Phoenix. You can choose to restore your virtual machine to the original location or the alternate location. 

Restore virtual machine to the original host

  1. Log on to Phoenix Management Console.
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
  3. On the menu bar, click VMs > Hyper-V.
  4. Click the Configured Virtual Machines tab.
  5. In the Name column, click the virtual machine name that you want to restore.
  6. Click Restore. The Restore VM wizard appears. 
  7. From the Snapshots panel, expand Hot, Warm, or Cold. Hot snapshots are available if Phoenix CloudCache is configured in your infrastructure. 
  8. Select a snapshot from the left-side panel, and click Full VM Restore.
  9. In the next step, select Original Location and click Next
  10. In the Restore Summary step, verify all your selections and click Finish

Note: If you change the virtual machine configuration such as name, memory, and vCPUs after backing up the virtual machine:

  • Phoenix overwrites the updated configuration at the time of restore
  • Phoenix restores the virtual machine with original configuration such as name, memory, and vCPUs  of the virtual machine at the time of backup

After the agent fetches the virtual machine from the cloud, it performs the following tasks on the host:

  1. The agent deletes the virtual machine. Deleting the virtual machine does not delete the virtual machine's files and disks. 
  2. The agent downloads the disks and configuration files and restores them to the original location that Phoenix records at the time of backup. 
  3. The agent renames the files and disks in that location. The agent adds the suffix ‘.Phoenix.${restore_job_id} to the existing files and virtual disks. 
  4. The agent creates a virtual machine using the disks and configuration files it restores. 
  5. If a virtual disk was excluded in the backup policy, then the disk is not attached to the restored virtual machine. 
  6. A physical disk or shared disk attached to the original virtual machine is not attached at the time of restore. Phoenix does not backup physical disks or shared disks attached to a virtual machine.
  7. Virtual machine ID is preserved to let a user perform a guest repair.
  8. Virtual machine checkpoints created at the time of backup are preserved. 

Restore virtual machine to an alternate host

  1. Log on to Phoenix Management Console.
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
  3. On the menu bar, click VMs > Hyper-V.
  4. Click the Configured Virtual Machines tab.
  5. In the Name column, click the virtual machine name that you want to restore.
  6. Click Restore. The Restore VM wizard appears. 
  7. From the Snapshots panel, expand Hot, Warm, or Cold. Hot snapshots are available if Phoenix CloudCache is configured in your infrastructure. 
  8. Select a snapshot from the left-side panel, and click Full VM Restore.
  9. In the next step, select Alternate Location and provide the following details:
    Field Description
    VM Name If you choose an alternate location for restore, a new virtual machine is created on the destination host. Provide a name in this field that Phoenix uses to create a new virtual machine.
    Destination Hyper-V Host Select the destination Hyper-V host. 
    Configuration File Location Specify the location on the host where the configuration files are downloaded. You can choose: 
    • A local folder
      You can browse and select the destination folder
    • SMB share 
      Type the shared folder path
    Disk(s) Location Specify the location where the virtual disks are downloaded. You can choose:
    • A local folder
      You can browse and select the destination folder
    • SMB share 
      Type the shared folder path
    After you enter all the details, click Next
  10. In the last step, review all the details you provided and click Finish.

After the agent fetches the virtual machine from the cloud, it performs the following tasks on the host:

  1. Agent downloads the disks at the entered disk location and configuration files at the entered configuration file location.
  2. If disks or files are present in the entered location, the agent renames the files with suffix ‘.Phoenix.${restore_job_id}
    If multiple disks use the same name, the agent renames the disks by adding a suffix such as _1, _2, and _3
  3. The agent creates the virtual machine using the restored disks and configuration files and a new virtual machine ID.
  4. If a virtual disk was excluded in the backup policy, then the disk is not attached to the restored virtual machine. 

  5. A physical disk or shared disk attached to the original virtual machine is not attached at the time of restore. Phoenix does not backup physical disks or shared disks attached to a virtual machine.
  6. All checkpoints at the time of backup are preserved.

Note: The virtual machine is in powered-off state after it is restored.
