<# .SYNOPSIS Create a database copy in Azure SQL Database instance .DESCRIPTION Create a new database by cloning a database in Azure SQL Database instance .PARAMETER DatabaseServer The name of the database server If on-premises or classic SQL Server, use either short name og Fully Qualified Domain Name (FQDN) If Azure use the full address to the database server, e.g. server.database.windows.net .PARAMETER DatabaseName The name of the database .PARAMETER SqlUser The login name for the SQL Server instance .PARAMETER SqlPwd The password for the SQL Server user .PARAMETER NewDatabaseName Name of the new / cloned database in the Azure SQL Database instance .PARAMETER EnableException This parameters disables user-friendly warnings and enables the throwing of exceptions This is less user friendly, but allows catching exceptions in calling scripts .EXAMPLE PS C:\> Invoke-AzureBackupRestore -DatabaseServer TestServer.database.windows.net -DatabaseName AxDB -SqlUser User123 -SqlPwd "Password123" -NewDatabaseName ExportClone This will create a database named "ExportClone" in the "TestServer.database.windows.net" Azure SQL Database instance. It uses the SQL credential "User123" to preform the needed actions. .NOTES Author: Rasmus Andersen (@ITRasmus) Author: Mötz Jensen (@Splaxi) #> Function Invoke-AzureBackupRestore { [CmdletBinding()] [OutputType('System.Boolean')] param ( [Parameter(Mandatory = $true)] [string] $DatabaseServer, [Parameter(Mandatory = $true)] [string] $DatabaseName, [Parameter(Mandatory = $true)] [string] $SqlUser, [Parameter(Mandatory = $true)] [string] $SqlPwd, [Parameter(Mandatory = $true)] [string] $NewDatabaseName, [switch] $EnableException ) Invoke-TimeSignal -Start $StartTime = Get-Date $SqlConParams = @{DatabaseServer = $DatabaseServer; SqlUser = $SqlUser; SqlPwd = $SqlPwd; TrustedConnection = $false} $sqlCommand = Get-SqlCommand @SqlConParams -DatabaseName $DatabaseName $commandText = (Get-Content "$script:ModuleRoot\internal\sql\newazuredbfromcopy.sql") -join [Environment]::NewLine $commandText = $commandText.Replace('@CurrentDatabase', $DatabaseName) $commandText = $commandText.Replace('@NewName', $NewDatabaseName) $sqlCommand.CommandText = $commandText try { Write-PSFMessage -Level InternalComment -Message "Executing a script against the database." -Target (Get-SqlString $SqlCommand) Write-PSFMessage -Level Verbose -Message "Starting the cloning process of the Azure DB." -Target (Get-SqlString $SqlCommand) $sqlCommand.Connection.Open() $null = $sqlCommand.ExecuteNonQuery() } catch { $messageString = "Something went wrong while <c='em'>cloning</c> the Azure DB database."
