Hello all, Two questions: 1) I have been unsuccessful performing an offline defrag of the IS, problem seems to be that datastore and transaction logs are on different partitions? Priv1.edb and pub1.edb are on d:\ drive. Transaction logs are on e:\ drive, priv1.stm and pub1.stm are on c:\ drive. I think my problem lies in getting them all located when running the defrag utility but I can't discern switches needed or other methodology. Any help here greatly appreciated. 2) When I backup my Exchange box I get approximately 25GB of data but my .edb files are 14GB, the .stm files 2GB and the transaction logs 50MB. What am I not understanding that results in a backup of 25GB?
