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 Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if SourceSqlCredential 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 the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or 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 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, DisasterRecovery, Backup 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 only the backup device named backup01 from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster.
