The oVirt engine is an essential core component of the oVirt virtualization management platform. It provides a convenient way to centrally manage and monitor virtualized environments and plays an important role in critical moments. The backup function is particularly notable. It not only safeguards important data and system configurations, but also reduces the risk of business interruption.
Moreover, the backup function can effectively respond to potentially catastrophic events, making it an indispensable tool for maintaining the stability and data integrity of virtualized environments. With the backup of oVirt engine, administrators can rest assured that critical information is protected, ensuring the reliability and stability of their virtualized environments.
Backup is an indispensable tool for maintaining the stability of the virtualized environment and ensuring data integrity. Following that, a detailed overview of the steps involved in performing oVirt engine backup will be provided to ensure the comprehensive protection and reliability of critical information.
To backup oVirt engine, just follow these steps:
1. Set the cluster into global maintenance mode and execute on the node host:
hosted-engine --set-maintenance --mode=global
2. Use the command backup:
engine-backup
3. After the engine backup is completed, exit the cluster's global maintenance mode and execute the following on the node hosts:
hosted-engine --set-maintenance --mode=none
In addition to the critical task of backing up the oVirt engine, it is equally important to be prepared for engine recovery when needed. A disaster recovery plan plays a vital role in ensuring the continuity and availability of your oVirt environment.
To recover oVirt engine, just follow these steps:
1. Put the cluster into global maintenance mode and execute on the node host:
hosted-engine --set-maintenance --mode=global
2. To clear the configuration files and database of the original environment on the engine, execute the command:
engine-cleanup
3. To restore, execute
engine-back –mode=restore on the engine
To specify the location of the backup file, use the -file option (if the backup file was previously placed on an external storage server, it needs to be copied to the engine first). Use the –restore-permissions option to specify permissions, as shown below:
engine-backup --mode=restore --file=/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200703103111.backup --restore-permissions
4. Execute engine-setup and configure all defaults as follows:
engine-setup
5. After engine recovery is complete, remove the cluster from global maintenance mode and execute on the node host:
hosted-engine --set-maintenance --mode=none
6. Now you can go and access the restored engine
There is a close relationship between the backup of oVirt engine and the backup of VMs. This is because the oVirt engine is the core component used to manage and monitor the virtualized environment, while the VMs are the key elements that operate in this environment. To ensure the reliability and resilience of the entire virtualized environment, it is important to consider backing up both the oVirt engine and the VMs.
