Installation:
1. Wenn Du es das erste mal startest, erzeugt es einen Ordner mit dem Namen "SyncFolders_Script_aliases" auf deinem Start-Volumen und öffnet diesen.
2. In diesen Ordner ziehst Du zunächst Aliase der Quell-Ordner (ja Du kannst mehrere Ordner in einen Zielordner synchronisieren).
3. Diese Ordner-Alias bennenst Du um in SOURCE.. irgendwas, wichtig ist nur, dass SOURCE am Anfang steht
4. Dann erstellst Du da noch einen Alias deines Zielordners, den Du DESTINATION irgendwas nennst
Dann nur noch starten und das Skript legt los =)
Wie es funktioniert?:
Die Dateien werden an Hand von md5 Prüfsummen unterschieden. Jede Dateien, deren md5-Prüfsumme mit denen der Dateien im Zielordner nicht übereinstimmt, wird umbenannt, nach dem Schema (+OUT<aktuelles Datum>) und dann kopiert. Sollte es beim Kopieren zu Problemen kommen, wird die Datei wieder "zurück-benannt" und das Skript läuft weiter. Am Ende erscheint in dem Fall aber eine Fehlermeldung.
In dem Skript Ordner wird zudem ein Datei log.txt geführt, in der dann bei jedem Start geschrieben wird, wie viel wohin kopiert wurde und ob es Fehler gegeben hat...
