function Test-DbaFullRecoveryModel { <# .SYNOPSIS Find if database is really in the Full 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. This state is also known as 'pseudo-Simple'. 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 SQL Server instance. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER Detailed Returns default information plus 'Notes' column .NOTES Tags: DisasterRecovery, Backup Author: Claudio Silva (@ClaudioESSilva) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Test-DbaFullRecoveryModel .EXAMPLE Test-DbaFullRecoveryModel -SqlInstance sql2005 Shows all databases which actual configured recovery model is FULL and says if they are really in FULL recovery model or not .EXAMPLE Test-DbaFullRecoveryModel -SqlInstance . | Where-Object {$_.ActualRecoveryModel -ne "FULL"} Only shows the databases that are in 'pseudo-simple' mode. .EXAMPLE Test-DbaFullRecoveryModel -SqlInstance sql2008 | Sort-Object Server, ActualRecoveryModel -Descending Shows all databases which actual configured recovery model is FULL and says if they are really in FULL recovery model or not.
