J’ai développé un petit script PowerShell qui permet de sauvegarder toutes les sites collections WSS d’une ferme hors site collection d’administration.

Il ne prend pas de paramètre car il sauvegarde la ferme local.

[system.reflection.assembly]::LoadWithPartialName(“Microsoft.Sharepoint”)

#Pour resoudre Prb output
$bindingFlags = [Reflection.BindingFlags] “Instance,NonPublic,GetField”
$objectRef = $host.GetType().GetField(“externalHostRef”, $bindingFlags).GetValue($host)

$bindingFlags = [Reflection.BindingFlags] “Instance,NonPublic,GetProperty”
$consoleHost = $objectRef.GetType().GetProperty(“Value”, $bindingFlags).GetValue($objectRef, @())

[void] $consoleHost.GetType().GetProperty(“IsStandardOutputRedirected”, $bindingFlags).GetValue($consoleHost, @())
$bindingFlags = [Reflection.BindingFlags] “Instance,NonPublic,GetField”
$field = $consoleHost.GetType().GetField(“standardOutputWriter”, $bindingFlags)
$field.SetValue($consoleHost, [Console]::Out)
$field2 = $consoleHost.GetType().GetField(“standardErrorWriter”, $bindingFlags)
$field2.SetValue($consoleHost, [Console]::Out)
