Backup-Job schlägt fehl!

Hi Leute,

Ich hab einen Backup-Job und einen Maintanceplan auf einem MS SQL-Server 2005 eingerichtet.
Nun hab ich das Problem, dass der Maintance-Plan nicht ausgeführt wird.
Hier die Fehlermeldung:

"08/20/2009 14:24:41,DailyBackup.Subplan_1,Error,0,DUCK,DailyBackup.Subplan_1,(Job outcome),,The job failed. The Job was invoked by User DUCK\Administrator. The last step to run was step 1 (Subplan_1).,00:01:18,0,0,,,,0

Ich hab schon alles probiert, die Rechte auf dem Zielordner eingestellt, den Connectionstring und den Owner angepasst, aber es nutzt nichts.
Der Job will ned, weiß jemand was ich da noch tun kann?
