Our network administrator sticks with NTBackup for all his backups. He routinely checks Event Viewer on all the servers to ensure that the backup started, went smoothly and finished OK.
Except on Friday when one of our remote servers failed to finish although it didn’t log a reason why. Our network manager rebooted the server twice, each time trying to get the backup to start running. On examining Event Viewer he noticed that Microsoft Operations Manager had suffered a Critical Error trying to monitor the IIS logs folder. Of course he had no idea what this Operations Manager piece of software was 
and so quizzed me about it when arrived.
To get him off my back I uninstalled the MOM agent on that remote server whilst checking the Operations Console. I remarked that MOM had registered an event saying that drive E was low on space. Drive E is a large USB drive where all the backups are stored.
It doesn’t take too much thought to realise that the backups failed because there was no space on the drive. Yet the network administrator had blindly tried to get them to run without checking nor finding what the problem really was – as well as blaming the MOM agent for something totally unrelated. If it wasn’t for me, I wonder just how long it would have taken him to figure out what wrong 
?
