If its local:
	rsync -av srcdir destdir
if its remote:
	rsync -ave ssh srcdir host:/dest/dir
	(be sure and have sshd running on the remote, and write perms to the  
appropriate dirs)

also, look at rdiff-backup (i've been using it lately), its nicer for  
doing backups
you do a snapshot, and after that, incrementals so you can go back in  
time

here is an example of some backups I've done at work:
# rdiff-backup -l somehost::/some/dir
Found 13 increments:

Current mirror: Sat Nov 18 07:32:15 2006

If I do a straight restore, I'll get it from Sat Nov 18 @ 7:32, if I  
specify an increment I'll get it from, say, Nov 8 @ 6:42
