function Test-DbaRecoveryModel { <# .SYNOPSIS Find if database is really a specific recovery model or not. .DESCRIPTION When you switch a database into FULL recovery model, it will behave like a SIMPLE recovery model until a full backup is taken in order to begin a log backup chain. However, you may also desire to validate if a database is SIMPLE or BULK LOGGED on an instance. Inspired by Paul Randal's post (http://www.sqlskills.com/blogs/paul/new-script-is-that-database-really-in-the-full-recovery-mode/) .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server. .PARAMETER RecoveryModel Specifies the type of recovery model you wish to test. By default it will test for FULL Recovery Model. .PARAMETER Detailed Output all properties, will be deprecated in 1.0.0 release. .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: DisasterRecovery, Backup Author: Claudio Silva (@ClaudioESSilva) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Test-DbaRecoveryModel .EXAMPLE PS C:\> Test-DbaRecoveryModel -SqlInstance sql2005 Shows all databases where the configured recovery model is FULL and indicates whether or not they are really in FULL recovery model. .EXAMPLE PS C:\> Test-DbaRecoveryModel -SqlInstance . | Where-Object {$_.ActualRecoveryModel -ne "FULL"} Only shows the databases that are functionally in 'simple' mode. .EXAMPLE PS C:\> Test-DbaRecoveryModel -SqlInstance sql2008 -RecoveryModel Bulk_Logged | Sort-Object Server -Descending Shows all databases where the configured recovery model is BULK_LOGGED and sort them by server name descending .EXAMPLE PS C:\> Test-DbaRecoveryModel -SqlInstance localhost | Select-Object -Property * Shows all of the properties for the databases that have Full Recovery Model #> [CmdletBinding()] [OutputType("System.Collections.ArrayList")] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [PSCredential]$SqlCredential, [validateSet("Full","Simple","Bulk_Logged")] [object]$RecoveryModel, [switch]$Detailed, [Alias('Silent')] [switch]$EnableException ) begin { Test-DbaDeprecation -DeprecatedOn 1.0.0 -Parameter Detailed Test-DbaDeprecation -DeprecatedOn 1.0.0 -Alias Test-DbaFullRecoveryModel if(Test-Bound -ParameterName RecoveryModel -Not){ $RecoveryModel = "Full" } switch($RecoveryModel){ "Full" {$recoveryCode = 1} "Bulk_Logged" {$recoveryCode = 2} "Simple" {$recoveryCode = 3} } $sqlRecoveryModel = "SELECT SERVERPROPERTY('MachineName') AS ComputerName, ISNULL(SERVERPROPERTY('InstanceName'), 'MSSQLSERVER') AS InstanceName, SERVERPROPERTY('ServerName') AS SqlInstance , d.[name] AS [Database] , d.recovery_model AS RecoveryModel , d.recovery_model_desc AS RecoveryModelDesc , CASE WHEN d.recovery_model = 1 AND drs.last_log_backup_lsn IS NOT NULL THEN 1 ELSE 0 END AS IsReallyInFullRecoveryModel FROM sys.databases AS D INNER JOIN sys.database_recovery_status AS drs ON D.database_id = drs.database_id WHERE d.recovery_model = $recoveryCode" if ($Database) { $dblist = $Database -join "','" $databasefilter += "AND d.[name] in ('$dblist')" } if ($ExcludeDatabase) { $dblist = $ExcludeDatabase -join "','" $databasefilter += "AND d.[name] NOT IN ('$dblist')" } $sql = "$sqlRecoveryModel $databasefilter" Write-Message -Level Debug -Message $sql } process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $sqlcredential -MinimumVersion 9 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } try { $results = $server.Query($sql) if (-not $results) { Write-Message -Level Verbose -Message "Server '$instance' does not have any databases in the $RecoveryModel recovery model." } foreach ($row in $results) { if (!([bool]$row.IsReallyInFullRecoveryModel) -and $RecoveryModel -eq 'Full') { $ActualRecoveryModel = "SIMPLE" } else{ $ActualRecoveryModel = "$($RecoveryModel.ToString().ToUpper())" } [PSCustomObject]@{ ComputerName = $row.ComputerName InstanceName = $row.InstanceName SqlInstance = $row.SqlInstance Database = $row.Database ConfiguredRecoveryModel = $row.RecoveryModelDesc ActualRecoveryModel = $ActualRecoveryModel } | Select-DefaultView -Property ComputerName,InstanceName,SqlInstance,Database,ConfiguredRecoveryModel,ActualRecoveryModel } } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } } } } |
