There is more to the solution than meets the eye
Check your scheduled Jobs,
they must reference a bks file in the form "@c:\pathname\filename.bks"
If your job is in the form
C:\WINDOWS\system32\ntbackup.exe backup systemstate /n "Monday... you need
to change it to
C:\WINDOWS\system32\ntbackup.exe backup "@c:\pathname\filename.bks" /n "Monday
When you apply the changes, you will probably need to add the job password
again.
Next
Use NTBACKUP to load that bks selection file, and in the selections, as well
as SYSTEM State ticked, a file on the same drive as your ADLOGs must be
ticked, optionally tick a dummy file on all drives. If you were not using a
selections file before, you need to save thse selections and go back to step
1 above to reference this file - note the "@" is ESSENTIAL, or you will just
backup the bks file.
Next
Test run your sheduled Job
I note that the Job type should be normal or copy e.g." /m normal" in the
scheduled job command line, otherwise if the file is not changed since the
last archive the attribute will not be set and this MAY cause the file to be
ignored and the System state to fail as well as no shadow was created- I am
not sure.
