Un script shell peut très bien faire le travail :
copier entre ---- DEBUT et ----- FIN dans un fichier par exemple darc.sh à mettre dans ~/bin, faire un chmod 755 ~/bin/darc.sh dans une fenêtre Terminal, et ensuite
~/bin/darc.sh Nom_du_dossier_à_sauvegarder
créera un Nom_du_dossier à sauvegarder.dmg.tgz, une image dmg du dossier compactée avec tar et gzip,
seule restriction pas d'espace dans le Nom_du_dossier_à_sauvegarder
(la restriction ne s'applique pas aux fichiers/dossiers inclus dans le dossier à sauvegarder)
le Nom_du_dossier_à_sauvegarder peut-être un fichier, il peut y avoir plusieurs noms... dans ce cas une archive par paramètre (voir aussi option -o)
différentes options
-r effacera le dmg intermédiaire
-R effacera le dmg ET l'original
-l listera le contenu du backup dans un .txt
-L listera le contenu du backup dans un .bom
(man mkbom)
-v travaille en mode "verbeux" (plus de message)
-o archive_file_name spécifie le nom e la dmg et si l'on pase plusieurs paramètres, ils seront TOUS dans cette archive unique
-h donne les explications (en anglais)
comme quoi en lisant les pages man on peut faire beaucoup de choses : man ditto mkbom lsbom hdiutil hdid grep awk sh test
Eviter quand même de faire un sudo darc.sh -R sur /bin ....
