Exadata Cloud Compute Node Backup and Restore Operations for RoCE systems (Doc ID 2782912.1)

Last updated on JULY 16, 2021

Applies to:

Gen 2 Exadata Cloud at Customer - Version N/A to N/A [Release All Releases]
Oracle Cloud Infrastructure - Exadata Cloud Service - Version N/A to N/A [Release N/A]
Linux x86-64 on Oracle Public Cloud

Goal

Per the Exadata Cloud Services description, operational management, including backup of the virtual machine, is a customer responsibility. Oracle Cloud Services automatically manages basic Exadata Cloud Services virtual machine backups for catastrophic failures. The Oracle Cloud managed virtual machine backups should be supplemented by a customer managed virtual machine backup solution to meet any additional backup and restore requirements.

This document describes the backup and restore of a Exadata Cloud Services virtual machine using snapshot based backups managed by the customer.

The procedure described in the note applies only to KVM Guest (RoCE) Exadata based systems: x8m and x9m.

For other Exadata hardware, see MOS note 2670579.1.
