Careful with those alerts! If you have a slower connection to your DR site or if maintenance causes larger than normal T log backup file size you will get alerts and plenty if the frequency of the check is short. I setup the schedule for the alert to not run during that time. To me, one of the best features of log shipping besides the obvious is how forgiving it is. There have been times I needed to take down either the source or destination and I've never had issues with things coming back online. I know the way it works is why this is possible but I appreciate the simplicity. We use log shipping and replication and generally things run smooth.
