Azure File Share Snapshot

Question

I am new to Azure, we have an Azure file share in the China region, but unfortunately the China region does not provide the function of Azure file backup. So I can only find some Powershell code from the web to produce snapshots. Below is the code, but when test run it keeps saying "does not contain a method named 'Snapshot'."

System.Management.Automation.RuntimeException: Method invocation failed because [Microsoft.WindowsAzure.Commands.Common.Storage.ResourceModel.AzureStorageFileShare] does not contain a method named 'Snapshot'.

Can someone help me fix this? I wish you a happy day！

Param(
 [string]$KeyVaultName,
 [string]$SecretName,
 [string]$StorageAccountName,
 [string]$FileShareName
)

# Authenticate with your Automation Account
$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Add-AzAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationID $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint -Environment AzureChinaCloud

#Create Snapshot
$keyvaultsecret = (Get-AzKeyVaultSecret -vaultName $KeyVaultName -name $SecretName -AsPlainText)
$context = New-AzStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $keyvaultsecret 
$share = Get-AzStorageShare -Context $context -Name $FileShareName
$share.Snapshot()

# Generate Snapshot List
$SnapshotList = Get-AzStorageShare -Context $context | Where-Object {$_.Name -eq $ShareName -and $_.IsSnapshot -eq $true -and $_.SnapshotTime -lt ([datetime]::UtcNow.AddDays(-4))}

# Delete Snapshots older than 4 days
foreach ($Snapshot in $SnapshotList)
    {
        Remove-AzStorageShare -Share $Snapshot -Verbose -Force
    }

can you check the following

Param(
 [string]$KeyVaultName,
 [string]$SecretName,
 [string]$StorageAccountName,
 [string]$FileShareName
)

# Authenticate with your Automation Account
$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Add-AzAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationID $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint -Environment AzureChinaCloud

#Create Snapshot
$keyvaultsecret = (Get-AzKeyVaultSecret -vaultName $KeyVaultName -name $SecretName -AsPlainText)
$context = New-AzStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $keyvaultsecret 
$share = Get-AzStorageShare -Context $context -Name $FileShareName
$shareObj = [Microsoft.Azure.Commands.Management.Storage.Models.PSFileShare]::new($share.ICloudFileShare)
$shareObj.Snapshot()

# Generate Snapshot List
$SnapshotList = Get-AzStorageShare -Context $context | Where-Object {$_.Name -eq $FileShareName -and $_.IsSnapshot -eq $true -and $_.SnapshotTime -lt ([datetime]::UtcNow.AddDays(-4))}

# Delete Snapshots older than 4 days
foreach ($Snapshot in $SnapshotList)
    {
        Remove-AzStorageShare -Share $Snapshot -Verbose -Force
    }
