What's the best way to use SuperDuper to back up multiple hard drives to partitions on a single drive? Here's the setup I'm setting up:


Mac HD (500GB SSD)
Media HD (2TB SSD)
Daily Backup HD (3TB HDD, partitioned into a 2TB Daily Backup Mac HD, a 500GB Daily Backup Media HD, and an irrelevant 500GB Spare HD)
Time Machine HD, (4TB, but this drive isn't relevant for my question).


Using SuperDuper, what's the proper way to back up two separate drives to partitions on a single external drive?  Can I back up my Mac HD and my Media HD at the same time?  It'll be running automatically in the middle of the night, so speed isn't a concern.  I've been backing up one drive M/W/F and the other T/T/S, but I'd like to switch to backing both drives up daily.  With SuperDuper, can I schedule both to run at the same time?

Also: Since my Mac and Media drives are SSD but my backup drive is a partitioned HDD, is there anything I should be careful of when I format the backup drive?

EDIT: I'm specifically asking about backing up multiple hard drives to separate partitions on a single drive.  I already have an external 3TB drive partitioned for backups.  If my Mac hard drive dies, I like having a bootable backup ready to go in an instant without needing to restore it first.  If my Media drive dies, I like having a backup ready to go without needing to restore it first.  I also have another external drive for Time Machine.  I'm religious about backing everything up (safety first, as they say).  I just want to make sure it's fine to back up two hard drives to two partitions on a single drive at the same time.
Actually this is quite possible to store the backups, all different drives on one volume with little effort. The magic words here are "back up to a disk image."

When you select the destination in SuperDuper one of the options is Disk Image. Just give the disk image a name and point it at your backup drive and all files will go into the disk image, completely accessible and completely separate from everything else on that drive.

If you like you can also encrypt the disk image for added security but you would have to create an encrypted sparseimage DMG from within Disk Utility first. I think that would work, never tried it but it makes sense it would.
