I am using NT Backup to back up my Win2003 Server. In NT Backup, I have selected the entire C:\ drive, the System State, and the Microsoft Information Store. I am under the impression that NT Backup on Win 2003 uses the Volume Shadow Copy to backup open files, and when I look at a backup catalog, I see that the .edb and .stm files are listed in the backup.
My question is this: Am I backing up the Exchange DB twice? I know that the .edb and .stm files are pretty much useless for restoring the Exchange Information Store, but how about for a full server restore? Do I need them for that? Or is it OK to exclude the .edb and .stm files from the backup as long as I have the Microsoft Information Store selected?
Thanks in advance.
