Murphy's Law can apply anywhere anytime and my recent re-installation of SharePoint is certainly no exception to the rules.
Soon after I finished recreating our SharePoint intranet, I stared sharing it with my immediate colleagues. While I was not really expecting some "Oh!" and "Aaah!" cheerful comments, I was still hoping for some kind of "Cool, it's back, thanks for the tool.".
But no, even that was expecting too much. The very first comment I received was an assassin comment like: "And I suppose you managed to retrieve all files stored in the previous SharePoint database ?". That comment triggered a machine-gun like stare from me to my colleague. No, I did not manage so far to retrieve these files and yes I had tried already. SQL Management Studio did not really help me by the way.
I had been cornered and really had to find a solution this time. So I returned to the web, googling frantically, trying various unsuccessful solutions until finally my patience and stubbornness got rewarded. I found found a great article from Keith Richie describing how to export the site content from a SharePoint Database for recovery purpose.
His article include a small source code and instruction to compile and run the program. It worked almost like a charm from the first run. Yet, as some of the recovered files were quite large, I had to boost the buffer size (as I worked locally this was not a problem) and even tweak the SQL query to work on a per directory basis to limit the execution run time. Happily this time SQL Server Management Studio was of great help to test and fine-tune the queries. Within 30 minutes from the moment I read Keith's post I had recovered all files I needed.
Today all files are imported in the new SharePoint and I preciously kept the program source and instruction ... just in case one day I need to recover files from another SharePoint database.

Restoring data from failed SharePoint server is not an easy task. A third party SharePoint database recovery software may help the users to get upto 100 % data in such type situations. One of the best and globally used application can be downloaded from here:

Here is a little script to export File-Blobs as Files from a sharepoint database directly (without Sharpoint Web running)
' VBS to read a BLOB (actually Image) column in SQL Server and save each row's image to a file.
' Example here reads PDFs stored in DocImage.Image column and saves each to a PDF file.
set oFS=CreateObject("Scripting.fileSystemObject")
sub MakePath(p)
if oFS.FolderExists(p) then exit sub
i=instrrev(p,"\")
if i=0 then return
MakePath(left(p,i-1))
WScript.Echo("Create '"+p+"'")
oFS.CreateFolder(p)
end sub
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
if WScript.Arguments.Count < 3 then
WScript.Echo "Sorry, you have to enter some details for export:"
WScript.Echo "BlobExport.vbs "
WScript.Echo " is the SQL-Server name and instance e.g. 'SPSRV\SQLEXPRESS'"
WScript.Echo " is the name ob the sharpoint database"
WScript.Echo " is the source path - without starting URL"
WScript.Echo " is the destination path for the export (for example 'D:\Willi')"
WScript.Quit 0
end if
sqlserver = WScript.Arguments.Item(0)
database = WScript.Arguments.Item(1)

outPath = WScript.Arguments.Item(3)
WScript.Echo "SQL-Server: "+sqlserver
WScript.Echo "Database : "+database
WScript.Echo "Source : '"+source+"'"
WScript.Echo "Dest : "+outPath
Set rs = CreateObject("ADODB.Recordset")
