我们需要备份 azure 数据库并将其存储在 blob 中，以便可以恢复它。我看过这个博客，但它使用第三方 cmdlet。

http://weblogs.thinktecture.com/cweyer/2011/01/automating-backup-of-a-sql-azure-database-to-azure-blob-storage-with-the-help-of-powershell-and-任务调度器.html

有人可以指导/帮助如何使用powershell实现上述目标。

Azure DB 不支持备份到 WA Blob Store，而是使用 PITR 功能为您自动备份。您会发现以下文档很有用：

希望这可以帮助。

首先完成您的 Azure 自动化设置（请参阅此处）。

编辑打击脚本并将其保存为 .ps1 文件。当您第一次运行它时，它会询问您的 Azure 自动化帐户和数据库凭据。在此过程中，它会将您的凭据安全地保存在本地文件中（请参阅此处如何完成）。在病房的这段时间之后，它使用保存的凭据。

.psl 文件和加密的凭证文件应存储在一个目录中

一旦你满意，你可以安排它在任务调度程序中运行。 

function Get-MyCredential
{
param(
$CredPath,
[switch]$Help
)
$HelpText = @"

    Get-MyCredential
    Usage:
    Get-MyCredential -CredPath `$CredPath

    If a credential is stored in $CredPath, it will be used.
    If no credential is found, Export-Credential will start and offer to
    Store a credential at the location specified.

"@
    if($Help -or (!($CredPath))){write-host $Helptext; Break}
    if (!(Test-Path -Path $CredPath -PathType Leaf)) {
        Export-Credential (Get-Credential) $CredPath
    }
    $cred = Import-Clixml $CredPath
    $cred.Password = $cred.Password | ConvertTo-SecureString
    $Credential = New-Object System.Management.Automation.PsCredential($cred.UserName, $cred.Password)
    Return $Credential
}


function Export-Credential($cred, $path) {
      $cred = $cred | Select-Object *
      $cred.password = $cred.Password | ConvertFrom-SecureString
      $cred | Export-Clixml $path

这是我的PowerShell脚本
