Hi, I am using DPM 2007 to backup our Exchange 2007 server. The backup works fine but it does NOT clear the transaction log files in our data stores. I am doing a nightly express full backup and I don't have a synchronization schedule except before creating a recovery point. Any suggestions or ideas why the transaction log files don't clear will be greatly appreciated. Thank you.

Do you have the Run Eseutil to check data integrity Check box enabled in your DPM protection group?-Steve

I did check the "Run Eseutil to check data integrity". The strangest thing is that it was working fine until one day it just stopped clearing up the log files. Any suggestions or ideas will be greatly appreciated. Thank you.
