Windows server backup fails consistency check of the Exchange database

Trying to backup Exchange 2010 and purge transaction logs using the built-in Windows Server Backup app (Windows 2008).

– Backup completes but with warnings and log files won’t purge

-Found that the backup will run successful only if database files and the transaction log files on the same volume

Moved the transaction logs files via the EMC to the save volume as the databases and got past the consistency check failure issue, and got a good backup w/flushed logs.
