Hello,<br />
<br />
even with all the native protection offered by DAG, we will be continuing to backup Exchange 2010. <br />
We have 3 databases in the DAG and all are active on a single server. The passive member of the DAG only contains passive DBs.<br />
<br />
question: if we backup the Active copy using MS recommended method of VSS to truncate logs.<br />
Do we need to do anything to the passive copy for log truncation? What mechanism is in place to allow us to keep the logs on the passive under control, or is that not an issue.<br />
