I've encountered a unique scenario with my WHS 2011 installation on a headless HP ex485 MediaSmart Server. At least unique from what I can tell. I used a server called AirVideo HD to stream movies to mobile devices and then airshare it to a TV box (ie Apple TV). It worked great on WHS v1, but after I upgraded to WHS 2011 and wanted to take advantage of the automated server backup in the event I screw something up along the way of tweaking, since it really is a pain in the rear to re-install the server from scratch and all.
Anywho, after adding the media folders to my streaming server, the server backup requires that drive/folder to be added to the bare metal system recovery. Seeing as how I have almost a TB of movies, then add in the OS backup and client PC backups. That server backup now surpasses the 2TB limit.
At first I thought it was StableBit StoragePool causing this error. But after moving files around and deleting the storage pool and recreating and hours and hours of pulling my hair out, I was able to figure out it was the media streaming software. A support tech from StableBit suggested Plex to me. So I tried plex out and thought it was a pretty slick setup. Didn't even need a paid app for my mobile devices. A day later when the server went to back itself up, I encountered the same problem. My server backups were exceeding the 2TB limit again. This made me conclude that the media streamers link to the data is somehow triggering the server backup to require the data to be backed up as well, since it's linked to the streaming server.
I've had AirVideo HD and Plex installed as a windows service running under the Administrator credentials. Perhaps this may be causing the problem, but seems silly if it were. The only way I can get a proper backup is to have the streaming server shutdown while the backup runs. But again, this is a silly resolution.
Has anyone else encountered this? Or is anyone else able to replicate this? How can I resolve this without disabling things to get other things to run?
