I second using Clonezilla. It doesn't make a single file, but splits things into 2G files that aren't as unwieldy as larger files. Keep a copy of the Clonezilla CD or image with the backup. > 2.

Copying a FreeBSD disk is better done with dump and restore. I have some notes on all three of these methods in Backup Options For FreeBSD: http://www.wonkity.com/~wblock/docs/html/backup.html
