function Get-XpDirTreeRestoreFile { <# .SYNOPSIS Internal Function to get SQL Server backfiles from a specified folder using xp_dirtree .DESCRIPTION Takes path, checks for validity. Scans for usual backup file .PARAMETER Path The path to retrieve the restore for. .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER SqlCredential Credential object used to connect to the SQL Server as a different user .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 PS C:\> Get-XpDirTreeRestoreFile -Path '\\foo\bar\' -SqlInstance $SqlInstance Tests whether the instance $SqlInstance has access to the path \\foo\bar\ #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [string]$Path, [parameter(Mandatory)] [DbaInstanceParameter]$SqlInstance, [System.Management.Automation.PSCredential]$SqlCredential, [switch]$EnableException, [switch]$NoRecurse ) Write-Message -Level InternalComment -Message "Starting" $server = Connect-SqlInstance -SqlInstance $SqlInstance -SqlCredential $SqlCredential $pathSep = Get-DbaPathSep -Server $server if (($path -like '*.bak') -or ($path -like '*.trn')) { # For a future person who knows what's up, please replace this comment with the reason this is empty } elseif ($Path[-1] -ne $pathSep) { $Path = $Path + $pathSep } if (!(Test-DbaPath -SqlInstance $server -path $path)) { Stop-Function -Message "SqlInstance $SqlInstance cannot access $path" } if (!(Test-DbaPath -SqlInstance $server -path $Path)) { Stop-Function -Message "SqlInstance $SqlInstance cannot access $Path" } if ($server.VersionMajor -ge 14) { # this is all kinds of cool, api could be expanded sooo much here $sql = "SELECT file_or_directory_name AS subdirectory, ~CONVERT(BIT, is_directory) as [file], 1 as depth FROM sys.dm_os_enumerate_filesystem('$Path', '*') WHERE [level] = 0" } elseif ($server.VersionMajor -lt 9) { $sql = "EXEC master..xp_dirtree '$Path',1,1;" } else { $sql = "EXEC master.sys.xp_dirtree '$Path',1,1;" } #$queryResult = Invoke-DbaQuery -SqlInstance $SqlInstance -Credential $SqlCredential -Database tempdb -Query $query $queryResult = $server.Query($sql) Write-Message -Level Debug -Message $sql $dirs = $queryResult | Where-Object file -eq 0 $Results = @() $Results += $queryResult | Where-Object file -eq 1 | Select-Object @{ Name = "FullName"; Expression = { $path + $_.subdirectory } } if ($True -ne $NoRecurse) { foreach ($d in $dirs) { $fullpath = $path + $d.subdirectory Write-Message -Level Verbose -Message "Enumerating subdirectory '$fullpath'" $Results += Get-XpDirTreeRestoreFile -Path $fullpath -SqlInstance $server } } return $Results } |
