I'd look at rsync:
http://networking.earthweb.com/netos/article.php/10951_1573881_3
1. Install rsync into /usr/local/
2. Create a seperate user account for the backup process on the server
you are going to copy from and to. I create a user called rsync on both
servers.
3. Use ssh-keygen and create create a key without a password
ssh-keygen -t dsa
- Place the file id_dsa in the .ssh directory of the rsync user
- Place the file authorized_keys into the server .ssh directory of where
the data will be copied to.
4. Make sure that the ssh daemon allows keys. You can usually find the
config for this under /etc/ssh/sshd_config
5. Add this to your crontab -e under the user rsync
0 0 * * * /usr/local/bin/rsync -av -e ssh [copy from directory]
rsync@[ip address]:[copy to directory]
