Backupexec 2014 utilising external USB drives as backup target. Each day the current drive is removed and a new one is inserted (from a pool of 5).
Each day a random or couple of random usb drives that are not connected to the server generate the 'offline' error in BE. Doesn't seem to have any effect on the actual running of things - if the drives are plugged in then they work just fine - its just generating huge numbers of alerts.
The problem of generating seemingly false alerts like this is that I cant use this fault condition to notify local users that a real fault exists.
