Getting ready
To properly archive WAL files, we recommend that you provision a server dedicated to backups or file storage. Depending on the transaction volume, an active PostgreSQL database might produce thousands of these daily. At 16 MB apiece, this is not an idle concern. For instance, for a 1 TB database, we recommend at least 3 TB of storage space.
Also, we will be using rsync as a daemon on this archive server. To install this on a Debian-based server, execute the following command as a root-level user:
sudo apt-get install rsync
Red Hat-based systems will need this command instead:
sudo yum install rsync xinetd
