Many moons ago I worked on a Windows graphical shell for Tarsnap. It never really went anywhere and I mostly forgot about it.

I was never quite sure what people wanted from such a client, which is partly why development stalled. If you just want something a little easier to use (click buttons, browse folders, etc.), I’ve got you covered. If you wanted some sort of Enterprise Workgroup management interface, I figure you already have far greater access to and familiarity with tools that can help do that than I do.

The one pain point I can imagine individual Windows users having that isn’t solved is simply getting Tarsnap running. Compiling Tarsnap from source may be outside the comfort zone of a lot of users. (As far as I know, the only way to compile or run tarsnap.exe is via cygwin.) Maybe I could host a Windows version, but do you trust me? Also there’s the problem of the cygwin dependency. It’s actually only a few DLLs which can be easily copied, but then I’m on the hook for providing the source to build cygwin1.dll, too. FWIW, once you’ve gotten tarsnap.exe built, it’s easily portable to other Windows systems that don’t have cygwin. Details in the readme.txt file.
