After using another Backup program, I discovered FBackup last week, and I must say that I am quite pleased. Congratulations, you won me.
In time, I'm sure there'll be some things that I'd like to see improved or enhanced, but for the moment the thing that bothers me most is the logo. (That's a good thing huh, if the logo is the one thing... ;-)
The logo is too complicated, and therefore hardly unrecognizable. Particularly the favicon/tray-icon where resolution is against us, becomes a blur of gray and black pixels.
Maybe you should consider something different, more simple, more elegant. What the hack, even a simple stylized FB, like with doPDF, would do much better for recognition than this little robot which just has too much detail.
I'm not much of an artist, so I hope you'll find some inspiration elsewhere.
In the meantime, I've offered my assistance for the Dutch translation in another thread.
