PowerShell Drivesnapshot Backup Script
Da ich mittlerweile ein Fan von der Imaging Software Drivesnapshot bin habe ich mich mal hingesetzt um das ganze zu Automatisieren.
Rausgekommen ist ein kleines feines PowerShell Script das natürlich an die lokalen Gegebenheiten angepasst werden muss.
Das Script erstellt im Ziel Pfad zuerst einen Ordner mit der Kalenderwoche, in diesem landet ein Voll Image und an den darauffolgenden Tagen jeweils ein Differentielles.
Wenn im Ziel Pfad Images älter als 2 Wochen gefunden werden, löscht das Script diese Automatisch um ein Voll laufen des Datenträgers zu verhindern.

#Drivesnapshot Backup Script by Michael Reischl http://www.gamorz.de /-/ Alpha 0.2
#This Script takes Images per Week, in every Week Folder you´ll find one full Image and 6 Differential Images.
#The Hash file is Stored directly on C Drive
#Images Older than 2 Weeks got Deleted in Standard Setting
#Base Informations
$date = Get-Date -Format dddd.d.MM.yyyy #Get the Date in a easy Readable Form.
$time = Get-Date -uFormat %T #Get Time when Backup Starts
$week = get-date -uFormat %V #Get Week Number
$destbackup = "\\path\to\your\backup\folder\$week" #Backup Destination Folder with Week Number

#Create the Backup Destination Folder Based on Week Number, if the folder exists go further.
if (!(Test-Path -path $destbackupmk\$week))
{
New-Item $destbackupmk\$week -type directory
}

$check = (Get-Childitem $destbackup | Measure-Object).count
#Take the Image and Store the Hash file on C Drive for Diff backups!
if ($check -le 0)

Das Script ist sicherlich nicht perfekt aber ein guter Ansatz auf dem man Aufbauen kann.
Zum schluss möchte ich noch meinen Dank an Tom Ehlert aussprechen der dieses Geniale Stück Software Programmiert hat!
