function Get-DbaBackupHistory {
    <#
        .SYNOPSIS
            Returns backup history details for databases on a SQL Server.
 
        .DESCRIPTION
            Returns backup history details for some or all databases on a SQL Server.
 
            You can even get detailed information (including file path) for latest full, differential and log files.
 
            Backups taken with the CopyOnly option will NOT be returned, unless the IncludeCopyOnly switch is present
 
            Reference: http://www.sqlhub.com/2011/07/find-your-backup-history-in-sql-server.html
 
        .PARAMETER SqlInstance
            SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
        .PARAMETER SqlCredential
            Credential object used to connect to the SQL Server Instance as a different user. This can be a Windows or SQL Server account. Windows users are determined by the existence of a backslash, so if you are intending to use an alternative Windows connection instead of a SQL login, ensure it contains a backslash.
 
        .PARAMETER Database
            Specifies one or more database(s) to process. If unspecified, all databases will be processed.
 
        .PARAMETER ExcludeDatabase
            Specifies one or more database(s) to exclude from processing.
 
        .PARAMETER IncludeCopyOnly
            By default Get-DbaBackupHistory will ignore backups taken with the CopyOnly option. This switch will include them
 
        .PARAMETER Force
            If this switch is enabled, a large amount of information is returned, similar to what SQL Server itself returns.
 
        .PARAMETER Since
            Specifies a DateTime object to use as the starting point for the search for backups.
 
        .PARAMETER Last
            If this switch is enabled, the most recent full chain of full, diff and log backup sets is returned.
 
        .PARAMETER LastFull
            If this switch is enabled, the most recent full backup set is returned.
 
        .PARAMETER LastDiff
            If this switch is enabled, the most recent differential backup set is returned.
 
        .PARAMETER LastLog
            If this switch is enabled, the most recent log backup is returned.
 
        .PARAMETER DeviceType
            Specifies a filter for backup sets based on DeviceTypes. Valid options are 'Disk','Permanent Disk Device', 'Tape', 'Permanent Tape Device','Pipe','Permanent Pipe Device','Virtual Device', in addition to custom integers for your own DeviceTypes.
 
        .PARAMETER Raw
            If this switch is enabled, one object per backup file is returned. Otherwise, media sets (striped backups across multiple files) will be grouped into a single return object.
 
        .PARAMETER Type
            Specifies one or more types of backups to return. Valid options are 'Full', 'Log', 'Differential', 'File', 'Differential File', 'Partial Full', and 'Partial Differential'. Otherwise, all types of backups will be returned unless one of the -Last* switches is enabled.
 
        .PARAMETER LastLsn
            Specifies a minimum LSN to use in filtering backup history. Only backups with an LSN greater than this value will be returned, which helps speed the retrieval process.
 
        .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.

        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance SqlInstance2014a
 
            Returns server name, database, username, backup type, date for all backups databases on SqlInstance2014a. This may return many rows; consider using filters that are included in other examples.
 
        .EXAMPLE
            $cred = Get-Credential sqladmin
            Get-DbaBackupHistory -SqlInstance SqlInstance2014a -SqlCredential $cred
 
            Does the same as above but logs in as SQL user "sqladmin"
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance SqlInstance2014a -Database db1, db2 -Since '7/1/2016 10:47:00'
 
            Returns backup information only for databases db1 and db2 on SqlInstance2014a since July 1, 2016 at 10:47 AM.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance sql2014 -Database AdventureWorks2014, pubs -Force | Format-Table
 
            Returns information only for AdventureWorks2014 and pubs and formats the results as a table.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance sql2014 -Database AdventureWorks2014 -Last
 
            Returns information about the most recent full, differential and log backups for AdventureWorks2014 on sql2014.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance sql2014 -Database AdventureWorks2014 -Last -DeviceType Disk
 
            Returns information about the most recent full, differential and log backups for AdventureWorks2014 on sql2014, but only for backups to disk.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance sql2014 -Database AdventureWorks2014 -Last -DeviceType 148,107
 
            Returns information about the most recent full, differential and log backups for AdventureWorks2014 on sql2014, but only for backups with device_type 148 and 107.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance sql2014 -Database AdventureWorks2014 -LastFull
 
            Returns information about the most recent full backup for AdventureWorks2014 on sql2014.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance sql2014 -Database AdventureWorks2014 -Type Full
 
            Returns information about all Full backups for AdventureWorks2014 on sql2014.
 
        .EXAMPLE
            Get-DbaRegisteredServer -SqlInstance sql2016 | Get-DbaBackupHistory
 
            Returns database backup information for every database on every server listed in the Central Management Server on sql2016.
 
        .EXAMPLE
            Get-DbaBackupHistory -SqlInstance SqlInstance2014a, sql2016 -Force
 
            Returns detailed backup history for all databases on SqlInstance2014a and sql2016.
