7 Backup and Restore

This chapter provides instructions for administrators who work with the integrated backup service. The purpose of this service is to store data that allows a crucial system service or component to be restored to its last known healthy state. It does not create backups of the environment created by users of the cloud resources in the Compute Enclave.

Caution:

Backup Retention

To optimize storage space consumption, the Backup and Restore Service applies a retention period of 14 days. When a backup operation runs, backups older than the retention period are deleted from shared storage on the ZFS Storage Appliance.

Automatic purging of backups – regardless of whether it is a standard daily backup or a manually triggered operation – is particularly critical for backups of the MySQL database. If a MySQL backup must be stored longer than the retention period, for example because it represents an important restore point, ensure that the data is copied to another location before the retention period expires. Contact your Oracle representative for assistance.

See Identifying Converted Snapshots for information about when the retention period does not apply and you need to manually delete snapshots.

Caution:

In appliance software version 3.0.2-b1081557 and newer, the monitoring data from Prometheus is not included in automated backups. To preserve your Prometheus data, create a backup and restore it manually. For more information, refer to the note with Doc ID 3021643.1.

For implementation details and technical background information for this feature, see "Backup and Restore" in the Appliance Administration Overview chapter in the Oracle Private Cloud Appliance Concepts Guide.
