Question

我在Azure中托管了2个数据库，一个生产环境和一个临时环境。一夜之间，我希望使用生产数据库的副本清除和恢复登台数据库。

有没有人知道这是否可以通过azure或我需要编写自己的自定义脚本？我查看了Azure Data Sync，但看起来它会合并数据。

谢谢，

您可以使用“复制数据库”功能将其复制到同一个或另一个逻辑服务器：

首先选择database backup of production to a storage account

$subscriptionId = "YOUR AZURE SUBSCRIPTION ID"

Login-AzureRmAccount
Set-AzureRmContext -SubscriptionId $subscriptionId

# Database to export
$DatabaseName = "DATABASE-NAME"
$ResourceGroupName = "RESOURCE-GROUP-NAME"
$ServerName = "SERVER-NAME"
$serverAdmin = "ADMIN-NAME"
$serverPassword = "ADMIN-PASSWORD" 
$securePassword = ConvertTo-SecureString -String $serverPassword -AsPlainText -Force
$creds = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $serverAdmin, $securePassword

# Generate a unique filename for the BACPAC
$bacpacFilename = $DatabaseName + (Get-Date).ToString("yyyyMMddHHmm") + ".bacpac"

# Storage account info for the BACPAC
$BaseStorageUri = "https://STORAGE-NAME.blob.core.windows.net/BLOB-CONTAINER-NAME/"
$BacpacUri = $BaseStorageUri + $bacpacFilename
$StorageKeytype = "StorageAccessKey"
$StorageKey = "YOUR STORAGE KEY"

$exportRequest = New-AzureRmSqlDatabaseExport -ResourceGroupName $ResourceGroupName -ServerName $ServerName `
   -DatabaseName $DatabaseName -StorageKeytype $StorageKeytype -StorageKey $StorageKey -StorageUri $BacpacUri `
   -AdministratorLogin $creds.UserName -AdministratorLoginPassword $creds.Password
$exportRequest

# Check status of the export
Get-AzureRmSqlDatabaseImportExportStatus -OperationStatusLink $exportRequest.OperationStatusLink

现在try restoring using below powershell

# Restore a database to a previous point in time

#$resourceGroupName = {resource-group-name}
#$serverName = {server-name}
$newRestoredDatabaseName = "{new-database-name}"
$localTimeToRestoreTo = "{12/9/2016 12:00:00 PM}" # change to a valid restore point for your database
$restorePointInTime = (Get-Date $localTimeToRestoreTo).ToUniversalTime()
$newDatabaseEdition = "Basic"
$newDatabaseServiceLevel = "Basic"

Write-Host "Restoring database '$databaseName' to its state at:"(Get-Date $restorePointInTime).ToLocalTime()", to a new database named '$newRestoredDatabaseName'."

$restoredDb = Restore-AzureRmSqlDatabase -FromPointInTimeBackup -PointInTime $restorePointInTime -ResourceGroupName $resourceGroupName `
 -ServerName $serverName -TargetDatabaseName $newRestoredDatabaseName -Edition $newDatabaseEdition -ServiceObjectiveName $newDatabaseServiceLevel `
 -ResourceId $databaseToRestore.ResourceID

$restoredDb

这些entire things can be automated as well
