function Copy-DbaBackupDevice { <# .SYNOPSIS Copies backup devices one by one. Copies both SQL code and the backup file itself. .DESCRIPTION Backups are migrated using Admin shares. If the destination directory does not exist, SQL Server's default backup directory will be used. If a backup device with same name exists on destination, it will not be dropped and recreated unless -Force is used. .PARAMETER Source Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher. .PARAMETER SourceSqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER BackupDevice BackupDevice to be copied. Auto-populated list of devices. If not provided all BackupDevice(s) will be copied. .PARAMETER Force If this switch is enabled, backup device(s) will be dropped and recreated if they already exists on destination. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Migration, Backup Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires: sysadmin access on SQL Servers .LINK https://dbatools.io/Copy-DbaBackupDevice .EXAMPLE PS C:\> Copy-DbaBackupDevice -Source sqlserver2014a -Destination sqlcluster Copies all server backup devices from sqlserver2014a to sqlcluster using Windows credentials. If backup devices with the same name exist on sqlcluster, they will be skipped. .EXAMPLE PS C:\> Copy-DbaBackupDevice -Source sqlserver2014a -Destination sqlcluster -BackupDevice backup01 -SourceSqlCredential $cred -Force Copies only the backup device named backup01 from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If a backup device with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used. .EXAMPLE PS C:\> Copy-DbaBackupDevice -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force Shows what would happen if the command were executed using force. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess, ConfirmImpact = "Medium")] param ( [parameter(Mandatory)] [DbaInstanceParameter]$Source, [PSCredential]$SourceSqlCredential, [parameter(Mandatory)] [DbaInstanceParameter[]]$Destination, [PSCredential]$DestinationSqlCredential, [object[]]$BackupDevice, [switch]$Force, [switch]$EnableException ) begin { if (-not $script:isWindows) { Stop-Function -Message "Copy-DbaBackupDevice does not support Linux yet though it looks doable" return } try { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $Source return } $serverBackupDevices = $sourceServer.BackupDevices $sourceNetBios = $Source.ComputerName if ($Force) {$ConfirmPreference = 'none'} } process { if (Test-FunctionInterrupt) { return } foreach ($destinstance in $Destination) { try { $destServer = Connect-SqlInstance -SqlInstance $destinstance -SqlCredential $DestinationSqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $destinstance -Continue } $destBackupDevices = $destServer.BackupDevices $destNetBios = $destinstance.ComputerName foreach ($currentBackupDevice in $serverBackupDevices) { $deviceName = $currentBackupDevice.Name $copyBackupDeviceStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = $deviceName Type = "Backup Device" Status = $null Notes = $null DateTime = [Sqlcollaborative.Dbatools.Utility.DbaDateTime](Get-Date) } if ($BackupDevice -and $BackupDevice -notcontains $deviceName) { continue } if ($destBackupDevices.Name -contains $deviceName) { if ($force -eq $false) { $copyBackupDeviceStatus.Status = "Skipped" $copyBackupDeviceStatus.Notes = "Already exists on destination" $copyBackupDeviceStatus | Select-DefaultView -Property DateTime, SourceServer, DestinationServer, Name, Type, Status, Notes -TypeName MigrationObject Write-Message -Level Verbose -Message "backup device $deviceName exists at destination.
