Script out XMLA for all databases

Question

I have several SSAS databases. I only want to script out the XMLA for them on a nightly basis. This will be a second tier backup in addition to the regular backups we have.

How do I auto-generate XMLA scripts for all the databases?

How were they deployed in the first place? If they were deployed through an SSAS project, to me at least, that seems like a backup already. Assuming the project files are in source control, which is backed up regularly. — Jon Seigel, Oct 07 '13 at 16:21
Yes, some of them are in Source Control, but I want a snapshot of the database as is on Prod (with the new partitions, for example). — Raj More, Oct 07 '13 at 16:33

You can do it using powershell.

$serverName = "servername\instanceName" 
$outputFolder = "D:\data\"
load the AMO and XML assemblies into the current runspace
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices") > $null 
[System.Reflection.Assembly]::LoadWithPartialName("System.Xml") > $null 
$dateStamp = (get-Date).ToString("yyyyMMdd")
connect to the server
$svr = new-Object Microsoft.AnalysisServices.Server 
$svr.Connect($serverName) 
foreach ($db in $svr.Databases) 
{ 
    write-Host "Scripting: " $db.Name 
    $xw = new-object System.Xml.XmlTextWriter("$($outputFolder)DBScript_$($db.Name)_$($dateStamp).xmla", [System.Text.Encoding]::UTF8) 
    $xw.Formatting = [System.Xml.Formatting]::Indented 
    [Microsoft.AnalysisServices.Scripter]::WriteCreate($xw,$svr,$db,$true,$true) 
    $xw.Close() 
} 
$svr.Disconnect()
