I have a SBS 2003 which is running backup fine every night.
It has three partitions, with the current 'data' sizes in brackets;
C: Main system Partion (18GB)
B: Which is a data drive (40GB)
E: Which contains the exchange information store only (24GB) - installed on the E: when the server was configured.
So total data size for the backup would be about 82GB.
I can see that in the backup (ntbackup) logs that we're backing up approx 116GB which looking through I can see that we're backing up C, B & E and then also backing up the first information store as well, so in effect - backing up the E: drive twice.
My question is should I exclude the E: drive from the backup configuration - however, I don't want to stop the backup of the first information store either. I'm assuming that ntbackup will continue to back the information store up irrespective of whether the drive has been excluded or not.
