Thanks, Stu!

(1) My system is configured as follows. I have a dual 800MHz G4 QuickSilver machine with 1.5GB RAM. I have two internal drives, one is the original "master", an 80GB Seagate, and one is a drive I added, a 120GB Seagate "slave". I also have two external FW drives. One is a 200GB LaCie d2 single FW interface, and the other is a 200GB d2 triple interface. On the internal master drive resides most of my data, including everything but music and movies (about 30 GB at present, counting Apps, System, Library, Users, etc.), and I am using the slave as a backup clone. One of the external d2's holds the data I can't fit on the internal drive, namely media (music and movies), which is currently about 90GB. I am currently backing that stuff up on the other d2. I am wondering if you think this is an optimal backup strategy, or if in your wisdom, you see a better solution.
Well, in general, I'd suggest keeping your backup on an external drive. If you're dealing with drives that are about the same age, remember that their MTBF is going to be about the same, too. The last thing you want are both drives being "active" for the same number of hours!

So, I'd probably suggest backing everything up to the external drive, and using the slave as your 'extra' drive (for the movies and music), and then using the externals as your clones.

I don't want to use the Copy Different/Copy Newer functions, since they don't delete the stuff I might have deleted on the original drive. The only option I see is to partition the drive, one partition for /Users (from my Master drive) and another for /Music and /Movies (from my #1 external drive). Do you see any other solutions? LaCie's SilverKeeper does offer folder level backup options and I was wondering if this might be a realistic future addition for your program.
Take a look at the FAQ entitled "How do I update an image?" This'll explain how to create an image file that you can use for this kind of backup -- one that is generally even better than using a "folder root".

To provide the flexibility needed to allow wildcards in file specifications (and to go as fast as possible), SuperDuper! doesn't make two passes over the data, once to get a 'tree' of files (which are pruned by the selections), and then a second to actually back things up. We evaluate both passes on the fly, which is why you're seeing directories go by that aren't getting copied -- they're getting evaluated, in one pass.

However, when I explore the constituent folders in each drive, and check the size of these, everything appears to be there. What accounts for this large discrepancy? Could it be invisible/system files? If so, shouldn't they be copied in a clone. 20GB seems like a lot of data to be "superfluous".
Well, it depends a lot on what was going on. You can see, by looking at the copy scripts, exactly what we're skipping. Perhaps you had a lot of temporary or VM swap files? We don't know of any cases where files aren't being copied, and as you might guess, we check for this all the time...

It makes things more convenient, and lessens the chance of making a mistake when manually setting the configuration options each backup session. However, it would be useful to have a delete function for old, unwanted settings files. Currently, I have to manually delete the file in the Application Settings folder (no big deal, but just giving a suggestion for a trivial feature, nonetheless).
Yeah, we didn't want to provide a whole lot of UI for something that could be done pretty easily in the Finder. Part of our philosophy is to minimize this kind of thing. But, we've got some ideas here that might make it in there later on...

What, specifically, are you looking for?

Thanks, Stu -- my pleasure.
