After several years of getting their teeth on Linux, Debian and Wheezy, switching to installations on different machines, with one or more internal hard drives that required the use of LVM, it became necessary to upgrade its software to be able to use the evolutions of other software like for example PHP 5 within the framework of web developments.

This complete reinstallation of the system also eliminated all functions, servers, security systems, monitoring, device drivers that had been installed for testing, or out of curiosity or to learn the techniques used in general computer.

The starting point is also different, since the operations of backup, preparations, ... are made from Linux and not from Windows.
