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 destination directory does not exist, SQL Server's default backup directory will be used. If 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 greater. .PARAMETER SourceSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Destination Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $dcred = Get-Credential, then pass this $dcred to the -DestinationSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER Force Drops and recreates the backup device if it exists. .PARAMETER Silent If this switch is enabled, the internal messaging functions will be silenced. .NOTES Tags: Migration, DisasterRecovery, Backup Original Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Copy-DbaBackupDevice .EXAMPLE 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 Copy-DbaBackupDevice -Source sqlserver2014a -Destination sqlcluster -BackupDevice backup01 -SourceSqlCredential $cred -Force Copies a single backup device, 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 Copy-DbaBackupDevice -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force Shows what would happen if the command were executed using force. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true)] [DbaInstanceParameter]$Source, [PSCredential] $SourceSqlCredential, [parameter(Mandatory = $true)] [DbaInstanceParameter]$Destination, [PSCredential] $DestinationSqlCredential, [switch]$Force, [switch]$Silent ) begin { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential $destServer = Connect-SqlInstance -SqlInstance $Destination -SqlCredential $DestinationSqlCredential $source = $sourceServer.DomainInstanceName $destination = $destServer.DomainInstanceName $serverBackupDevices = $sourceServer.BackupDevices $destBackupDevices = $destServer.BackupDevices Write-Output "Resolving NetBios name" $sourceNetBios = Resolve-NetBiosName $sourceServer $destNetBios = Resolve-NetBiosName $destServer } process { foreach ($backupDevice in $serverBackupDevices) { $deviceName = $backupDevice.Name $copyBackupDeviceStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = $deviceName Type = "BackupDevice" Status = $null DateTime = [Sqlcollaborative.Dbatools.Utility.DbaDateTime](Get-Date) } if ($backupDevices.Length -gt 0 -and $backupDevices -notcontains $deviceName) { continue } if ($destBackupDevices.Name -contains $deviceName) { if ($force -eq $false) { $copyBackupDeviceStatus.Status = "Skipped" $copyBackupDeviceStatus Write-Message -Level Warning -Message "backup device $deviceName exists at destination.
