Unfortunately, the transaction log files grow very quickly, but not at a consistent time of day that I can tell.</p> <p>While I can truncate the logs, this breaks the log chain for DPM. What I am looking for is to understand what is causing the tansaction logs to grow so quickly and large (20 GB), and what I can do to control their size without truncating the logs.</p> <p>Thoughts?</p> <p>Richard</p><div style="clear:both;"></div>
