dal suo help:
There are two typical scenarios in which you may want to clone
the contents of your source volume to a subfolder of the target volume
rather than the root level of the target volume: 1) You maintain items
at the root level of your target volume that you do not want to be
erased, yet you want to do incremental backups, deleting items on the
backup that were deleted from the source. 2) You want to use the target
volume to back up more than one computer.
In the first scenario, your goal is to make regular, incremental
backups to a target volume, deleting from the backup the files that you
have deleted from the source. Except you don't want to delete items that
were on the target volume before you started backing up! In general,
these are conflicting goals. However, previous versions of CCC handled
this situation quite gracefully. CCC version 3 uses a different approach
to backing up than previous versions, and it is no longer capable of
simply excluding preexisting items on the target volume. There are two
solutions to this dilemma. The first is to use the "Clone to a
subfolder..." setting. By specifying a subfolder (simply indicate the
name of a folder, CCC will create it if it does not exist), CCC will
copy the contents of your source volume into a single folder on the
target volume. Any other files or folders on the target volume will be
left unaffected. If you choose to use the "Delete items that don't exist
on source", this rule will only apply to items within the subfolder that
you have indicated.
While this seems like the perfect solution to the problem, note
that you will not be able to boot from the backup volume, nor will you
be able to select the subfolder as a source volume. You can still access
your backup files via the Finder. An alternative to this method is to
place items from the target volume that you don't want to lose into a
directory prefixed with "_CCC", then specify the "Archive modified and
deleted items" option. When using this option, CCC automatically ignores
any directory prefixed with "_CCC", as that is the prefix used on the
directories used to store archives of modified and deleted items.
Another alternative is to clone to a disk image on the target. This
option is explained below.
In the second scenario, your goal is to backup multiple
computers. Despite that it is tempting, you are discouraged from using
the "Clone to subfolder" feature to solve this problem. Instead, you
should clone to separate disk images.
