Backup Object Tagging​

You can attach key-value metadata tags to backup artifacts—such as base backups, WAL files, and history files—via the .spec.configuration section of the ObjectStore resource.

  • tags: applied to base backups and WAL files
  • historyTags: applied to history files only

Example​

apiVersion: barmancloud.cnpg.io/v1
kind: ObjectStore
metadata:
  name: my-store
spec:
  configuration:
    [...]
    tags:
      backupRetentionPolicy: "expire"
    historyTags:
      backupRetentionPolicy: "keep"
  [...]

Extra Options for Backup and WAL Archiving​

You can pass additional command-line arguments to barman-cloud-backup and barman-cloud-wal-archive using the additionalCommandArgs field in the ObjectStore configuration.

  • .spec.configuration.data.additionalCommandArgs: for barman-cloud-backup
  • .spec.configuration.wal.additionalCommandArgs: for barman-cloud-wal-archive

Each field accepts a list of string arguments. If an argument is already configured elsewhere in the plugin, the duplicate will be ignored.

Example: Extra Backup Options​

kind: ObjectStore
metadata:
  name: my-store
spec:
  configuration:
    data:
      additionalCommandArgs:
        - "--min-chunk-size=5MB"
        - "--read-timeout=60"
