Thanks for the comments. Adding a cloned camera is a solution which I would like to avoid. For now I will use another software for continuous recording. But I don't think this is silly. Perhaps someone who thinks it's silly is using the software in a different way. I don't know what's silly about using already implemented features in
Blue Iris - motion detection already there, split recording on motion already there, conversion to another format from BVR already there, upload to FTP or moving to another folder already there.
I just want to stick to BVR on the server where Blue Iris runs but I want to upload a backup in H264 or another playable format to a backup server running Plex. The reason why I want to do this is because if a burglar comes, first thing he will do is disconnect power and cut cameras. Uploading last moments of motion to another location while on the UPS will allow me to 1) get an alert that power went down 2) that there was a motion detected just before the power went down and most importantly - 3) I will be able to access the recording and see what's was going on. With BVR recordings, I have two issues - one, they don't play in Plex and two, they're too large to be QUICKLY uploaded to a backup location - the upload must happen quickly so that there's time to upload the clip to offsite location before the UPS goes out and/or the burglar switches off the internet and/or Blue Iris server. If you think I'm asking a silly thing, then I'm probably using Blue Iris for a wrong purpose. This is not "waste" of CPU in my opinion but rather very meaningful use of CPU when it comes to running a surveillance software.
