Et j'utilise aussi duplicity pour /etc

A tenter aussi alors ! Plus y'a de choix mieux c'est. Finalement j'ai fait mes backups ce soir, et partclone marche à merveille, et en plus il est rapide

[waitnsea]

Bonjour,
Je fais mes sauvegardes-système depuis un cd-live monté sur une clef USB (j'utilise PMagic qui offre Clonezilla et partimage, mais il y en a plein d'autres, à commencer par l'iso d'installation d'Arch avec partclone comme détaillé) et un DD externe.
J'interviens juste pour dire que j'ai eu des erreurs en branchant en USB 3.0 et aucune en branchant en 2.0 (j'ai 2x USB 2.0 et un 3.0), mais ça doit dépendre des bécanes et des Bios, la mienne n'est pas très récente.
Pour les données seulement, avec Unison, tout se fait depuis une session normale bien sûr.

Personnellement, je suis fada de BTRFS

Attention ce n'est pas une sauvegarde, juste un moyen facile de naviguer dans l'historique. Si tu as le moindre souci, logiciel comme matériel, tu perds tout

[Xorg]

En terme de sauvegarde efficace mais coûteuse, il y a le RAID (niveau 1, 5, 6...). Si, par exemple j'ai deux disques durs en RAID 1, un disque dur lâche, j'aurais toujours les mêmes données sur le second et tout ne sera pas perdu.
Par contre, si le PC tombe du 100ème étage, ou qu'il y a un très gros incendie vers le PC, je ne garantis pas que tous les disques durs survivent.
Pour les fadas de LVM, il y a un moyen de faire du RAID 1 sans mdadm (réalisé ici grâce à ceci).

D'où l'intérêt d'avoir une sauvegarde externe au PC. Puis cumuler RAID et sauvegarde, ça fait un peu de la redondance, et c'est ça qu'il faut en terme de sauvegarde, de la redondance.

[benjarobin]

Le RAID n'est pas non plus une sauvegarde, bien que ce soit plus robuste que de ne rien avoir. Le RAID permet de se prémunir d'une défaillance matériel sur un ou plusieurs disques, mais ne protégera en aucune façon d'un problème d'alimentation, ou de tout autres problèmes matériels, un problème logiciel, un problème d’interface chaise-clavier, ...

Effectivement ! Mais ensuite, à grands coups de BTRFS send/receive ou de duplicity, je mets tout à l'abri ailleurs
