# Backups of authentik's database by CNPG itself, through the barman cloud
# plugin (apps/templates/plugin-barman-cloud-helm.yaml): a base backup every
# night, and every WAL segment as soon as it is full or 5 minutes old
# (archive_timeout). Both go to the bucket cnpg-authentik in Garage on the
# NAS (nas/garage), so the database can be restored to any moment of the
# last 30 days. Velero copies the data directory while PostgreSQL runs,
# which is not a consistent copy.
# The key is Garage's cnpg-authentik, in Vault as kv/cnpg-authentik-s3; it
# can only reach this bucket.
