PXE booting gives a lot of possibilities.  I use it to boot Clonezilla 
to back up Windows systems.  That is better than dd, since only used 
disk blocks are copied.  But neither does incremental backups.

For FreeBSD and other open operating systems, sysutils/rsnapshot is a 
possibility.  Normally run from cron, could be run manually, or 
automatically when the backup server is detected.  It does incremental 
copies, is space-efficient (rsync with hard links), and only depends on 
rsync and Perl.
