I am another of the several that are moaning about the lack of a backup capability for Repiter Host. I was tempted to ask the same question a year ago, but I poked around enough to get the feeling that I knew the answer.
Without second-guessing the reasons for the approach chosen, for my use and maybe some others, it makes it more difficult than any other program I use in 3D printing to be able to save/duplicate, or restore a complex installation of Repetier Host. I have a dedicated PC on my printer, and another desktop in a more comfortable area that I use for everything that leads up to actual printing. With other programs, it is an easy matter to place things like CAD files, Slicer profiles and model files in a cloud location so they are available everywhere. I'd like to do the same with Repetier Host configuration data so I can have the same setup in two locations.
I'm beginning to see a need for several defined printer profiles to accommodate a mixing extruder, a 2 to 1 switching extruder, and a conventional single and dual extruder configuration. Maybe some can become multi-purpose, but it is still a pain to reproduce one or more from photos-only. I took a look at the registry data, but I'm not likely to try to save or restore anything like that, and I sure can't make much sense out of what I saw.
I know there isn't much gain for the average user to justify a change, but I can hope that maybe if there is ever a lull in the process, a change will be considered. I recently took a look at the two Cura programs. While there is some interesting capability in the slicer and plug-ins, I was disappointed at the lack of control that I take for granted in Repetier Host. I believe I did manage to hook a later version of Cura Engine into RH, but otherwise, I have probably seen enough of Cura. Viva-La-Repetier-Host!
