Hi there,
We have Backup Exec 2014 SP1 installed on a Windows Server 2008 R2 and using a Buffallo Terastation as disk storage (1GB switch connection) between server and NAS.
I know the DLM runs several times a day and I don't think you configure it to start at a certain time (magic start time!)
We are finding that when a full SDR backup is run, sometimes the DLM kicks in and causes Backup Exec to error and drop it's connection to the NAS and leaves the job with a "loading media" state. Or it's just coincidence that it happens but we saw it a few times with BESX 2012. The only work around I've found is to chop the into small jobs with flat file, GRT (exchange) and system state and working around the times when the DLM process runs. Either our server does not have enough "horse power" 16 GB RAM should be enough. We want to achieve a full SDR backup at least once a week.
We've got servers with 2012 R2 and they have been running fine with no issues. I know that BESX2012 really shows down on system states on 2008 R2 servers.
If you have any thoughts and suggestions we would like to hear them.
