The LRS-CD module of the LRS

 
This module allows the creation of hard disk auto-recovery bootable CD-Roms. PC images that are stored on the LRS can be backed up on bootable CD-Roms.
 
It is particularily usefull for :

• portable computers ;
• PCs used for demonstrations. In the case a hard disk is damaged one just has to find a hard disk and to boot the PC on the CD-Roms. The PC is then restored in a few minutes (operating system, softwares, configuration) ;
• administrators that instal PCs that are not linked to the newtork or that are physically distant ;
• PC retailers that can offer fast recovery CD-Roms that contain the exact image of the hard disk originally sold.

 

1. The LRS-CD module

 
As for the LRS server administration module, the module that generates reinstalment CD-Roms is integrated to the webmin interface.
 

2. User interface

 
The only thing to do (excluding parameters, such as the maximal size of the CD-Roms that need to be generated) is to choose the image of the PC that will be used as a base for the reinstalment CD-Rom. The module takes care of :

• the distribution of the LRS's images according to the CD-Roms defined size (650Mo/700Mo ou autre) ;
• the generation of the ISO9660 images of the CD-Rom(s) ;
• the adding of boot-loader on the first CD-Rom so as to make it bootable.

 
 

3. Use of the reinstalment CD-Rom

 
The recovery of a PC with the CD-Rom(s) that has (have) been generated only requires to push on one button at boot and eventually change the CD-Rom if the capacity of the disk's backup is larger then the capacity of a single CD-Rom.
 
 

4. Modules for CD-Rom engraving

 
Webmin integrates already the modules needed to engrave directly the ISO9660 images generated by the LRS-CD modules, which creates automatically the necessary 'profiles' for the functionning of the module 'burner' (included in Webmin >=0.96).
 
It is also possible to engrave those images whith any engraving CD-Rom (Linux, Windows....).
 
The LRS-CD is included in the last versions of the Linbox Rescue Serveur.
