Migration Attic vers Borg¶

• https://github.com/borgbackup/borg/pull/231
• old: https://chiliproject.tetaneutral.net/projects/git-tetaneutral-net/repository/puppet-backup
• new: https://chiliproject.tetaneutral.net/projects/git-tetaneutral-net/repository/puppetmaster/revisions/master/entry/modules/ttnn/manifests/backup.pp
  • git history BackupPC => Attic => Borg

# apt-get -t jessie-backports install borgbackup
$ cd /backup/attic/
$ borg upgrade <repo>
$ borg check --repair <repo>
$ mv <repo> ../borg/
$ chown -R backupinfra: /backup/borg/<repo>

Dans le module puppet, le changement le plus important est le parametre compression explicite pour correspondre au défaut de attic create :

attic create ... <repo> -> borg create --compression zlib,6 ... <repo>

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.
