Some of the development versions of Clonezilla do understand UFS. It's
been a few months since I looked at this, and I need to go back and
figure out exactly which.

Others have already mentioned good points of dump and restore. They can
be used even on mounted partitions, so the system can stay up while a
backup is running. Some scripting could make restores as easy as
Clonezilla. A bare-metal restore could be made from a modified FreeBSD
install CD. Partition the target disk (interactively or not), locate
the dump files, restore them, then do any interactive fixup needed.
