Presented by:

Gratien D'haese is a Belgian independent IT Consultant who is already 25 years active in the Unix world (and with Linux since its invention in 1991). Gratien has a broad experience with Unix in general, Unix networking and security, big system administration tasks, clustering, consultancy and project management.

Gratien is quite active in the Unix/Linux Open Source world and is giving talks around various topics since the days of the Belgian UNIX Users Group and other organizations promoting Unix/Linux and the Open Source movement. On occasions he talks about his projects on conferences, such as at Fosdem, LinuxTag, T-Dose, and LOAD with talks around Relax-and-Recover, IPv6, upgrade-ux, adhocr. Gratien is the co-founder and main designer of Relax-and-Recover (rear) together with Schlomo Schapiro (from Germany). This project started in 2006 and the software is part of Fedora, EPEL and SLES HA - []

Linux Disaster Recovery exercises are not every day tasks and most system engineers lack experience how to practice them. This talk will describe the basic knowledge about Disaster Recovery (DR) and Business Continuity (BC) and go deeper into the different aspects of each. However, we will also show you how to start up DR plan and explain some handy tools, such as Relax and Recover (rear) so you can get started and being prepared. Rear can store the details about your systems on disks (NAS, USB, SAN,...) or network (PXE, NFS, CIFS,...) including the complete backup. It also creates a bootable image which you need to recreate your system from scratch. Furthermore, thanks to the modular concept, we can integrate rear with foreign backup solutions (commercial or not) to do the backup and restore part which makes rear very scalable in big enterprises. Rear scales even with Cloud solutions and is the heart of another great project (drlm or disaster recovery linux manager).
