Hi,
If you could give a bit more info, we can help.
IE
What drives are to be backed up?? C:, D:??
Do you need a log file, where do you want it to go on the drive?
Do you need to use hardware compression?
But the at command will be something like.
AT 23:00 /EVERY:M,T,W,TH,F C:\BACKUP.BAT
Also make sure the schedule service is running and set to automatic, to check this look in start/settings/control panel/services. Make sure the "schedule" or "task scheduler" service is started and set the automatic. If not start the service and set the startup type to automatic.
Where backup.bat is the batch file to backup the data.
A batch flie to backup the C: and D: drives, and the local registry then verify the data, and use hardware compression, then put the log file in a folder called c:\backuplogs would be.
@echo off
ntbackup backup C: D: /v /b /hc

n /l "c:\backuplogs\backup.log /t normal
ntbackup eject
Think thats about it.
