Yes, the DB is running on the same pi as the backend.

I don’t recall having to do anything special on the backend machine. I used the standard raspbian stretch desktop. Since I am not running a frontend(or Kodi) on the backend machine, video memory can be left at the default setting.

I have scheduled several recordings for this evening, and I will let it run overnight, but based on experimentation today, including recording 3 or 4 streams from each channel to ’saturate’ the channel, and watching one of them as it records, it works well as a recording only backend. It won’t be doing any fancy stuff such as comm flag or transcoding, but for just recording, it is working fine.

I did install phpmyadmin on the backend, so that also brings in apache on it as well.

When I did my earlier tests a few months ago using a sandisk USB 3 128Gb memory stick as the recordings directory the results were not  good. With a 3.5 inch external Toshiba drive, though it is working just fine as above.
