function Get-DbaDbRecoveryModel {
<#
    .SYNOPSIS
        Get-DbaDbRecoveryModel displays the Recovery Model.
 
    .DESCRIPTION
        Get-DbaDbRecoveryModel displays the Recovery Model for all databases. This is the default, you can filter using -Database, -ExcludeDatabase, -RecoveryModel
 
    .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
        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 RecoveryModel
        Filters the output based on Recovery Model. Valid options are Simple, Full and BulkLogged
 
        Details about the recovery models can be found here:
        https://docs.microsoft.com/en-us/sql/relational-databases/backup-restore/recovery-models-sql-server
 
    .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.
