• Hughes Systique Corp. > Research & Innovation > Newsletter > Issue 2 > mySQL – A typical MySQL cluster requires at least 4 nodes for deploying a High Available MySQL database cluster. The typical configuration of any enterprise application is a 2 Node solution (Active-Standby mode or Active-Active Mode). This is where the real challenge lies: in fitting the MySQL Cluster Nodes in the 2 Nodes offering the application services and then making it work in the configuration without a single point of failure.
• Corosync / Pacemaker – Execute script on failover – Raymii.org – With Corosync/Pacemaker there is no easy way to simply run a script on failover. There are good reasons for this, but sometimes you want to do something simple. This tutorial describes how to change the Dummy OCF resource to execute a script on failover. In this example it is a script which triggers a few SNMP traps, sends an alert to Nagios and sends some data to Graphite. SNMP alone could be done with the ocf:heartbeat:ClusterMon resource, but the other stuff not.

• UrBackup – Client/Server Open Source Network Backup for Windows and Linux – UrBackup is an easy to setup open source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time. File and image backups are made while the system is running without interrupting current processes. UrBackup also continuously watches folders you want backed up in order to quickly find differences to previous backups. Because of that incremental file backups are really fast. Your files can be restored through the web interface or the Windows Explorer while the backups of drive volumes can be restored with a bootable CD or USB-Stick (bare metal restore). A web interface makes setting up your own backup server really easy.
