Hi Wanda,

It could be caused by a premature termination of a prior backup.
You could check the DP/Exchange log and Windows Event Log to see if there are 
any signs of a premature failure just prior to the backups starting to fail. 
Look for a missing backup or incomplete console captures of the backups just 
prior to this problem.

You might be able to clear the condition by changing the passive to active and 
then back again. You could also try dismounting and mounting the database.

Thanks,

Del
