Building our own backup server using the Raspberry PI
by Michal Remias @ wpress.io:
We’ve been always thinking about building our own backup server using the ARM solution of Raspberry PI. When we needed to manage approx. 25 WordPress web projects couple of months ago we did some experiments with MainWP on virtual server at DigitalOcean.
To make the server a bit more reliable and stable, we decided to add a standalone power supply and a bit of intelligence to the whole solution. The additional components are not necessary but will help you to keep the server running even in the case of short power failures which could lead to damage of the backup files and errors in database.
