Depends on _what you want to back up. For backing up FreeBSD system
files, use dump(8). My machines have separate partitions for /, /usr and
/var. These are all backed-up by making dumps.
For backing up user data, like /home, I prefer rsync.
If my machine breaks, I can restore the system from dumps using nothing
but a boot CD and the dumps. (to get / and all ports back up and
running), and then use rsync to restore the user data.

Use the OS's native dump(8) command to back up the system
partitions. It's the best way to do a bare metal recovery.
For the rest, use rsync(1).
