Azure 數據庫隔夜復制

Question

我在 Azure 中托管了 2 個數據庫，一個生產環境和一個臨時環境。 一夜之間，我希望使用生產數據庫的副本清除和恢復臨時數據庫。

有誰知道這是否可以通過 azure 實現，或者我是否需要編寫自己的自定義腳本？ 我查看了 Azure 數據同步，但看起來它會合並數據。

謝謝，

Answer 1

首先將生產的數據庫備份到存儲帳戶

$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

現在嘗試使用以下 powershell 進行恢復

# 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

這些整個事情也可以自動化

您可以使用“復制數據庫”功能復制到同一台邏輯服務器或另一台邏輯服務器：
