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.
