  2. Sommaire • Introduction • Principes • Historiques • Bacula • Conclusion

  3. Introduction • Utilisation de l’informatique • Eviter les problèmes • Défaillance du matériel, • Erreur humaine… • Solution • Sauvegarde.

  4. Principes • Stratégies de sauvegarde • Client, • Serveur, • Internet. • Méthodes de sauvegarde • Complète, • Incrémentale, • Différentielle.

  5. Historique • Dump/Restore • Sauvegarde l'intégralité d'un système de fichiers d'un périphérique, • Complète, incrémental. • Tar • Créer une archive, • Rajouter/Extraire/Remplacer des fichiers, • Réaliser des différences.

  6. Historique • Cpio • Entrée/Sortie standard, • Formats de sortie possible : binaire, tar, … • Prise en compte des expressions régulières, • Tailles de blocs paramétrable.

  7. Historique • Avantages • Outils en ligne de commande, • Aisément « scriptables », • Utilisation très précise. • Inconvénients • Convivialité, • Possibilités, • Outils limités au monde Unix.

  8. Logiciels libres • Bacula • Backup + Dracula • Amanda • Advanced Maryland Automated Network Disk Archiver

  9. Bacula - Introduction • Libre sous licence GPL, • Grande modularité, • Sauvegarde, restauration et vérification des données, • Architecture client/serveur, • Gestionnaire d’évènements, • GZIP, • TLS, PKI.

  10. Bacula - Architecture • Bacula Director • Cœur du système, • Déclenche les sauvegardes, restaurations et vérifications, • Gère les catalogues.

  11. Bacula - Architecture • Storage daemon • Lecture/écriture des données sur support physique,

  12. Bacula - Architecture • File daemon • Service, • Communique avec le Director et le Storage daemon.

  13. Bacula - Architecture • Catalog database • SQL Database, • Stocke les informations relatives aux fichiers sauvegardés

  14. Bacula - Architecture • Console • Lister des informations, • Gestion manuelle des sauvegardes/restaurations.

  15. Bacula - Architecture

  16. Bacula - Configuration • 4 fichiers différents • Director, • File daemon, • Storage daemon, • Console. • Système de fonctions • Permet d’être modulable
