If the backup device is another IPBrick, the server must be prepared to act as a rsync server. First let's suppose that the client IPBrick machine has that configurations:
192.168.69.199;
ipbrick.domain.com;
At the IPBrick rsync server we need to:
ipbrick.domain.com;
rsync allways running when the server reboots:
update-rc.d rsync defaults 20
nano /etc/rsyncd.conf
uid = root
gid = root
use chroot = yes
[ipbrick.domain.com]
path = /home1/_shares/ipbrick.domain.com
hosts allow = 192.168.69.199
read only = false
write only = false
nano;
/etc/init.d/rsync start
Note: A complete network backup solution is also included at IPBrick, supporting tape and disk backup. Link: http://www.bacula.org.
