Hello.

I, too, would like the functionality of being able to do a Smart Update on the Users data only, without cloning or erasing the OS non-Users files. Or, for that matter, the ability to do a Smart Update on any subset of your data without cloning or erasing the rest of the files.

Three days ago I cloned my drive onto an external drive (using a Smart Update of all files) not realizing that since I had booted my stable system two days prior, something had happened which would allow it to boot but not progress to the login screen. Thus, I had damaged a booting system. It wasn't SuperDuper!'s fault, of course.

I don't use SuperDuper! so much to keep an identical copy of my internal disk as to keep an identical copy of my Users data (and my TeX installation, together with a few other scripts I've installed in /usr/local/bin/). I like to have a bootable external drive, however, so that I can boot from it now and then to run DiskWarrior or do other repairs (not too often). Of course, I could partition the external drive to have one with a pristine System to boot from and the other to have cloned data. That is what I guess I'll do.

Thank you for SuperDuper!. Please do not think of the above as a whine and that I think you owe it to me. I'm happy with SuperDuper! as it is and I think you've done more than enough for the registration fee.
