‘tank’ zfs pool (mirror)

The zfs pool is then used for the following filesystems, which share disk space (there isn’t a size limit for each):

  • containers/code

  • data/evboard

  • data/git

  • data/neon

  • data/phabricator

  • data/staging

  • data/sysadmin

Backups

There is nothing interesting in recluse itself; the important data is in the ‘code’ container. Thus, the backup script only gets configuration info: /etc, user cronjobs, and list of installed packages. They are sent to the Hetzner backup space via sftp.

Name etymology

The recluse spiders, also known as brown spiders, fiddle-backs, violin spiders, and reapers, is a genus of spiders that was first described by R. T. Lowe in 1832. They are venomous spiders known for their bite, which sometimes produces a characteristic set of symptoms known as loxoscelism.
