rsync setup details
Installing and Configuring rsync
Install rsync
(http://rsync.samba.org)
on both systems.
rsync will be using
the secondary network interfaces to transfer the data. The rsync setup is
pretty much how Rudy Pawul describes in the heartbeat document on rsync,
except that ssh is not being used.
The rsync configuration file, /etc/rsyncd.conf looks like the following:
use chroot = yes
hosts allow = 10.0.0.1
[postgresql]
path = /home/pgsql
uid = postgres
gid = postgres
read only = false
comment = PostgreSQL backup
(make sure 'hosts allow' is set to the secondary network interface of the
opposite system).
If you invoke the following command on the primary system,
/usr/bin/rsync -auv --delete /home/pgsql/ 10.0.0.2::postgresql/
you should see a copy of all the postgres files on the secondary in
/home/pgsql. If not, then your rsync installation isn't correct yet.
