pgbackrest is an amazing tool that saves entire PostgreSQL clusters with ease.

In this post we’ll go trough the configuration of the backup using a remote backup server.

For the extensive documentation and detailed instructions please refer to the user guide.

operating system configuration

For our example we’ll use two virtual machines on virtualbox with devuan 1.0 Jessie installed.

Each machine is configured in the same way.

• 1 cpu
• 1 GB ram
• Hard disk of 12 GB with single partition ext4
• sshd up and running

The machines have one bridged network adapter eth0. The network configuration is using a static ip address.

When I started writing pg_chameleon I had in mind a tool making simple to migrate from different dbms engines to PostgreSQL.

The name was inspired by the Culture Club’s Karma chameleon song which suggested me the idea of a tool capable to move data between different database technologies.

Then tool’s scope changed becoming a replica system rather a migration system but I’ve kept the name as I think the idea is still valid.
