Exchange: How to truncate DB Logs

Exchange constantly writes DB Logs to disk. These logs only get cleared when a backup is done.

If you need to clear those logs without a backup, use the following commands (if the DB log files are on the d: drive):

Open a cmd box with admin rights

diskshadow

add volume d:

begin backup

create

end backup

That's it. You should now have much more free disk space.
