Can rsync transfer data from a database to other database

[twang at cs.concordia.ca]

Hi all:

As we know rsync is powerful in transfer/backup files,
now my question is, is it possible to send/copy/backup 
a bunch of data from a database into other database? 

If yes, how?
If not, is there any other tool(s) able to do so?

Your any advice is appreciated.
Best regards!

Tony
