ntbackup doesn't run as scheduled, only manually

[aldi]

Hello,

I have ntbackup scheduled to run at midnight on a win 2003 server. The backup doesn't run at the scheduled time, but I can run it manually from the scheduled task.

Please see the settings below and let me know what is wrong with it:

C:\WINDOWS\system32\ntbackup.exe backup "@C:\Documents and Settings\MIAdmin\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\medibak.bks" /n "Media created 1/25/2007 at 10:00 AM" /d "Set created 1/25/2007 at 10:00 AM" /n "Media created 1/25/2007 at 10:00 AM" /v:yes /r:no /rs:no /hcn /m normal /j "mediinn" /l:f /p "4mm DDS" /UM

Thanks in advance!
