Hi to all
 
I have an exchange server Windows2003 (not in cluster) with TDP version 5.2.1 I 
backup it at Sunday Tuesday Thursday full (at 23:00) and between 3 times a day 
incremental (at 9 , 15 , 20).
 
The 3 incrementals after the full are running correctly but the second day I 
got the following error:
 
          Sunday                             Monday                            
Tuesday ........
            Full (23:00)   OK         I (09:00)   OK                   I 
(09:00)  Error
                                                   I (15:00)    OK              
    I (15:00)   Error
                                                   I (20:00)   OK               
   I (20:00)    Error

The database missed a previous full backup before the incremental backup. 
 
 
My backup copy group are:
 
Full backup       nolimit nolimit   8   8
Incr backup      nolimit nolimit  15  15
 
The Exchange administrator told me that is not running any defrag on the 
database .....
 
Any clue ?????
