The manual for QRecall is bundled in the application. Download it, install it, and chose Help > QRecall Help.
There's also a fairly recent copy of the manual on-line.
As long as you can mount the storage for your Micro PC as a volume on the Mac, QRecall should work.
While QRecall is focused on capturing and restoring macOS native filesystems, the archive can be stored on any volume that can be mounted on macOS, which includes networked servers, NAS devices, thumb drives and more. Not every filesystem is supported (because some are flawed), but that's the goal.
