| 41 | 4 | Mehdi Abaakouk | Dans le module puppet, le changement le plus important est le parametre compression: |
| 42 | 4 | Mehdi Abaakouk | |
| 43 | 4 | Mehdi Abaakouk | <pre> |
| 44 | 4 | Mehdi Abaakouk | attic create ... <repo>-> borg create --compression zlib,6 ... <repo> |
| 45 | 4 | Mehdi Abaakouk | </pre> |
| 46 | 4 | Mehdi Abaakouk | |
| 47 | 4 | Mehdi Abaakouk | Sinon le prochain backup sera non compressé, et aucun nouveau chucks ne correspondra aux anciens -> perte de la dedup. "zlib,6" étant le niveau de compression de attic. |
