NOTE : THIS IS NOT AN OFFICAIL SCRIPT FROM TINTRI.
To restore a virtual machine using the Tintri PowerShell Toolkit, you can follow these steps:

Step 1: Install the Tintri PowerShell Toolkit: Before you can use the Tintri PowerShell Toolkit, you need to install it. You can download the toolkit from the Tintri Support website and follow the installation instructions provided in the documentation.

Step 2: Connect to the Tintri VMstore: To interact with the Tintri VMstore, you need to establish a connection using the appropriate credentials. Use the following PowerShell code to connect to the Tintri VMstore:

# Import the Tintri PowerShell module
Import-Module Tintri.Powershell

# Set the VMstore IP address or hostname and credentials
$VMstoreIP = "VMSTORE_IP_ADDRESS_OR_HOSTNAME"
$Username = "USERNAME"
$Password = "PASSWORD"

# Connect to the VMstore
Connect-TintriServer -Server $VMstoreIP -Credential (Get-Credential -UserName $Username -Message "Enter Tintri Password")

Step 3: Get the Tintri Backup Details: To restore a virtual machine from a Tintri backup, you need to retrieve the backup details. Use the Get-TintriVmBackup cmdlet to list available backups:

# Specify the name of the VM and the backup date
$VMName = "VM_Name"
$BackupDate = "yyyy-MM-dd"  # Format: "2023-08-15"

# Get the Tintri backup details for the VM on the specified date
$Backup = Get-TintriVmBackup -Name $VMName -BackupDate $BackupDate

Step 4: Restore the Virtual Machine: Once you have the backup details, you can proceed with the restore operation using the Restore-TintriVmBackup cmdlet:

# Specify the name and folder for the restored VM
$RestoredVMName = "Restored_VM_Name"
$RestoredVMFolder = "Restored_VM_Folder"

# Restore the VM
$RestoredVM = Restore-TintriVmBackup -BackupId $Backup.Id -Name $RestoredVMName -FolderName $RestoredVMFolder

Step 5: Optional: Customize Restored VM Settings: If needed, you can customize the settings of the restored VM using the Tintri PowerShell cmdlets. For example, you can change the VM’s network settings, disk attributes, and other configurations using the appropriate cmdlets provided by the Tintri Toolkit.

Step 6: Disconnect from the Tintri VMstore: After completing the restore process, you can disconnect from the Tintri VMstore using the following PowerShell code:

# Disconnect from the VMstore
Disconnect-TintriServer

That’s it! The virtual machine has now been restored from the Tintri backup using the Tintri PowerShell Toolkit. Make sure to customize the restored VM settings according to your requirements before using it.
