As suggested:
- From Phiserman:
This can be done, although not with pull-cut Japanese saws. There is a tool that fits over the saw teeth to guide a file over the teeth. I believe I've seen this described in a tool sharpening book by "Lee." It takes patience, bright natural light, magnification and a keen eye.

This is one of those areas, "...where angels fear to tread."
The Galoots get into this pretty good, though. Here's a link to their search page.

usually refer to Leonard Lee's book on sharpening but even he doesn't have much to say about this. I just satisfy myself with following the old tooth configuration with a feather edge file.
Good luck. Regards, Tom Thomas J. Watson-Cabinetmaker Gulph Mills, Pennsylvania

From Tom Watson Charlie:
It bothered me that I couldn't lay my hand on an article dealing with this so I went on what I figured might turn out to be a snipe hunt.
Found a snipe, though.
Ian Kirby did a sidebar on sharpening backsaws (including dovetail saws) in issue #39 of FWW, which was later compiled into the Taunton, "Fine Woodworking On...", series book, "Hand Tools.
It looks pretty solid. If you don't have access to either of the above sources, I can scan it and send you a .jpg.

From ToolMiser Sounds interesting, and I would appreciate a copy of it also. I have two older saws that need to be touched up, and I always forget to ask my sharpening person if they can do them.
