Depending on the backup strategy that you want, I highly recommend  
rsnapshot (/usr/ports/sysutils/rsnapshot <http://www.rsnapshot.org/ 
 >). It handles most of the management of retaining past backups up  
to X days, X weeks, etc, and uses hardlinks to save space between the  
backups. So because it uses rsync, it uses the bandwidth of an  
incremental backup, but because it uses directory trees of hardlinks,  
each backup is completely restorable like a full backup.
