Backup

You can configure Block Storage (cinder) to back up volumes to Object Storage (swift) by setting variables. If enabled, the default configuration backs up volumes to an Object Storage installation accessible within your environment. Alternatively, you can set cinder_service_backup_swift_url and other variables listed below to back up to an external Object Storage installation.

  1. Add or edit the following line in the /etc/openstack_deploy/user_variables.yml file and set the value to True:

    cinder_service_backup_program_enabled: True

  2. By default, Block Storage will use the access credentials of the user initiating the backup. Default values are set in the /opt/openstack-ansible/playbooks/roles/os_cinder/defaults/main.yml file. You can override those defaults by setting variables in /etc/openstack_deploy/user_variables.yml to change how Block Storage performs backups. As needed, add and edit any of the following variables to the /etc/openstack_deploy/user_variables.yml file:

    ...
cinder_service_backup_swift_auth: per_user
# Options include 'per_user' or 'single_user'. We default to
# 'per_user' so that backups are saved to a user's swift
# account.
cinder_service_backup_swift_url:
# This is your swift storage url when using 'per_user', or keystone
# endpoint when using 'single_user'.  When using 'per_user', you
# can leave this as empty or as None to allow cinder-backup to
# obtain storage url from environment.
cinder_service_backup_swift_url:
cinder_service_backup_swift_auth_version: 2
cinder_service_backup_swift_user:
cinder_service_backup_swift_tenant:
cinder_service_backup_swift_key:
cinder_service_backup_swift_container: volumebackups
cinder_service_backup_swift_object_size: 52428800
cinder_service_backup_swift_retry_attempts: 3
cinder_service_backup_swift_retry_backoff: 2
cinder_service_backup_compression_algorithm: zlib
cinder_service_backup_metadata_version: 2

During installation of Block Storage, the backup service is configured. For more information about swift, refer to the Standalone Object Storage Deployment guide.
