All of us, who grew up using ntbackup for backing up Exchange databases by using disk-to-disk-to-tape method, were unsatisfied when we discovered that in Windows 2008 it was not possible anymore to use ntbackup as the tool of choice. Exchange 2007 backup was therefore complicated or impossible to execute with native tools.
With Exchange 2010 and Windows 2008 R2 it is possible to backup/recover Exchange databases by using Windows Backup tool. It uses VSS engine but supports truncating the Exchange logs when proper backup method is used.
When creating Backup Schedule it is necessary to select Custom and not Full server backup. The reason lies in VSS backup method. We need to select VSS Full backup later on.
When we click Advanced settings, VSS full backup must be selected in order logs to be properly truncated.
