function Restore-DbaBackupFromDirectory { <# .SYNOPSIS Restores SQL Server databases from the backup directory structure created by Ola Hallengren's database maintenance scripts. Different structures coming soon. .DESCRIPTION Many SQL Server database administrators use Ola Hallengren's SQL Server Maintenance Solution which can be found at http://ola.hallengren.com Hallengren uses a predictable backup structure which made it relatively easy to create a script that can restore an entire SQL Server database instance, down to the master database (next version), to a new server. This script is intended to be used in the event that the originating SQL Server becomes unavailable, thus rendering my other SQL restore script (http://goo.gl/QmfQ6s) ineffective. .PARAMETER SqlInstance The SQL Server instance to which you will be restoring the database. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Path Specifies the full path to the directory that contains the database backups. The SQL Server service must have read access to this path. .PARAMETER ReuseSourceFolderStructure If this switch is enabled, the folder structure used on the instance where the backup was made will be recreated. By default, the database files will be restored to the default data and log directories for the instance you're restoring onto. .PARAMETER NoRecovery If this switch is enabled, the database is left in the No Recovery state to enable further backups to be added. .PARAMETER Force If this switch is enabled, any existing database matching the name of a database being restored will be overwritten. .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. .NOTES Tags: DisasterRecovery, Backup, Restore Requires: sysadmin access on destination SQL Server. dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Restore-SqlBackupFromDirectory .EXAMPLE Restore-SqlBackupFromDirectory -SqlInstance sqlcluster -Path \\fileserver\share\sqlbackups\SQLSERVER2014A All user databases contained within \\fileserver\share\sqlbackups\SQLSERVERA will be restored to sqlcluster, down the most recent full/differential/logs. #> #Requires -Version 3.0 [CmdletBinding()] Param ( [parameter(Mandatory = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter]$SqlInstance, [parameter(Mandatory = $true)] [string]$Path, [switch]$NoRecovery, [Alias("ReuseFolderStructure")] [switch]$ReuseSourceFolderStructure, [PSCredential]$SqlCredential, [switch]$Force ) Write-Warning "This command is no longer supported.
