- | Has anyone tried Clonezilla as a backup solution and found it wanting? My problem has always been on a dual-boot PC (with Linux and that other operating system), where I have frequently stopped the machine from booting after somehow corrupting either the Linux OS, the GRUB boot menu, or both. While Clonezilla will, with a little prodding, back up the entire disk drive, it refuses point blank to restore just the Linux partition. Or, at least, it did the way that I used Clonezilla. | + | **Has anyone tried Clonezilla as a backup solution and found it wanting?

The program can create a backup using either its savedisk or saveparts feature. Savedisk allows the entire disk to be restored but will not restore single partitions. In contrast, saveparts will restore one or more partitions, but will not restore the master boot record or the partition table, and so can’t be used to restore the entire disk. Clearly, this is not very helpful when it comes to flexibility in restoring disks and/or partitions. | The program can create a backup using either its savedisk or saveparts feature.

Savedisk restaure le disque entier, mais pas une partition. En revanche, saveparts restaurera une ou plusieurs partitions, mais ni le MBR (secteur d’amorçage maître) ni la table des partitions et ne peut pas être utilisé pour restaurer le disque entier. Clairement cela n’aide pas quant à la flexibilité de la restauration d’un disque et/ou des partitions. |

It can be downloaded as an ISO file (the current version is rescuezilla-2.4.1-64bit.jammy.iso) that can be used to create a bootable USB flash drive. As the “jammy” portion of the filename indicates, the USB boots into a version of Ubuntu Linux; however, the Ubuntu desktop is initially hidden from the end user as Rescuezilla loads in full-screen mode. | ||

Cette dernière option est un travail en cours et devra finalement permettre de monter une partition disque à partir de l’image de sauvegarde afin d’en extraire des fichiers et des dossiers individuels. Toutefois, ici, nous allons examiner tout simplement les deux options principales – celles de Backup et Restore. | ||
