I have two 3 Terabyte drives for my images. One is the backup. When I backup, I use Superduper and have one drive mirror the other. Now I want an off site backup using three older external drives. Am I able to use Superduper to backup using all three drives? Or should i just drag folders manually. It is finally time for me to address this issue.

I never used Superduper or similar software, maybe I don't trust it too much ???
I also back up most of my work on at least two external devices, and do it manually. Still, I guess it depends on your workflow...

I use ChronoSync to run an incremental backup to an offsite machine (it's my mother's iMac, in fact, but it could as well be a NAS drive in her house) every night. It works, pretty much flawlessly, and even sends me an email telling me what it's backed up. Free updates for life, too. I recommend it. Look here (http://www.econtechnologies.com).

SuperDuper handles cloning local drives well. It's what I do.
Buy drives in triples. Put your working data on one drive. Clone via SuperDuper to another drive after each work day. Once a week, take the current back-up drive at work to your off-site storage (for me, my house), and then bring the back-up drive bring the back-up drive that was off-site to work. I carry just the drives, leaving the electricity adapters and data cables in place.
Never have all three drives in the same physical location.
IME, spanning back-ups across more than one drive requires to much administration (in short, I have to think about what's where). Your data is worth the cost of a new 3 TB drive. (If I understand, you are asking whether you can use SuperDuper to span a back-up of your 3 TB drives to three older drives.)
ChronoSync get recommended regularly. I haven't looked into it because I don't have high-speed Internet at my studio.

What ever you do - do it. and do it often
The last thing you want is a HD failure and then not to have a backup of that data. That would hurt. So keep it up.

I can't imagine going back to offsite physical drives anymore, such a PITA compared to the simplicity and ease of cloud solutions these days. Backblaze. Simple, cheap, fast (depending on your connection, but any pro should have a great connection if they are working). Do nothing, you are always covered.

I upload some of them to the clound. ;)

I will consider using rsync that is build into the mac and a couple of scripts. Carbon Copy Cloner is a less geeky solution.
Here is a how to:

I am not a professional photographer (I work on systems), and I have a fast connection, but keep in mind that not everybody lives on the first world and fast upload speed could be difficult to find in many places. For someone working with a one megabit upload speed 32GB is more than 71h using all the bandwidth (no internet access then) under perfect conditions.
And I can tell you 1Mbit upload is the best home service in Costa Rica at this moment for ADSL.
As they say :
Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

In places were you have capacity caps (not in my country) it could be cheeper too, just copy the disk and ship it to a safe location and get the current location disk back.
