Persistent data is placed in encrypted volumes otherwise it may be deleted at any moment, when the host fails. A daily backup of all volumes is done by the host in the backup-service-group group. Exactly one host must be set in the ~/.enough/example.com/inventory/services.yml file, like so:
backup-service-group: hosts: bind-host:
The number of backups is defined with the backup_retention_days variable as documented in this file and can be set in ~/.enough/example.com/inventory/group_vars/backup-service-group.yml like so:
--- backup_retention_days: 7
If the quota for volume snapshots displayed by enough –domain example.com quota show is too low, a support ticket should be opened with the cloud provider to increase it.
A volume backup can be used to restore a service in the state it was at the time of the backup.
The volumes are replicated three times and their data cannot be lost because of a hardware failure.
