Confused about "Cloning" and "Sharing"

Yes, that makes more sense to me.
But when this works best for a safety clone, why not for a full backup?
Why should a full backup have the same name?

BTW: yesterday I partitioned my backup drive into two partitions, one for a full mirror of my internal drive, and one for storing several backup archives as sparsed images. Works great! SuperDuper! is simple but yet powerful!

The things I like:

- Smart Update -> saves time
- custom copy scripts based on standard scripts -> ability to exclude files or to backup single directories
- use of sparse images -> let me create more than one backup set on my backup disk
- save configurations and let them run through applescript -> automate several backup/archiving tasks

As others said before: SuperDuper! is worth every cent.
