backup error - windows server 2003

Question

I have server loaded with windows 2003 it is scheduled for a system state backup using Ntbackup utility, for some time it worked fine as scheduled , since a couple of days the scheduled backup isn't running, so i have daily manual job of taking backup, even the system does not shows any error for failure.

Answer 1

• Check the scheduled task return code in the Scheduled Tasks app. That will give you clues as to what is happening.
• Verify that the user account that the task is running under is still valid. (Totally stolen from ErikA)
• Check the NT Backup log file for interesting bits of information. It's located at C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data
