What is the best way to image copy a FreeBSD system?

[Xn Nooby]

On Linux I use clonezilla, which understands the EXT3 filesystem, and
it can skip unused space (I'm using about 3GB out of 1TB).

On FreeBSD, I have to fill the 1TB drive with zero-filled files, then
delete them, on each partiton, since CloneZilla uses DD+gzip on the
entire drive.

I like to make image copies of new systems, so I can revert back to my
starting point in case I break it, but CloneZilla is taking 9 hours to
image the drive.  I can re-install a lot faster than that.

I normally store my image copies on a Samba share on another system,
they are stored as files.  I am not copying to another raw drive.

Is there an image-copy backup program that understands the UFS
file-system? Or perhaps there is a better solution on FreeBSD?
