Restoring Configuration Settings

Veeam Backup for Nutanix AHV offers restore of the configuration database that can be helpful in the following situations:

• The configuration database got corrupted, and you want to recover data from a configuration backup.
• The backup appliance got corrupted, and you want to recover its configuration from a configuration backup.
• The backup appliance went down, and you want to apply its configuration to a new backup appliance.
• You want to roll back the configuration database to a specific point in time.
• You want to apply the backed-up configuration of a Nutanix AHV backup appliance version 4.0 (or later) to a newly deployed Nutanix AHV backup appliance.

When you restore the configuration database of a Nutanix AHV backup appliance, consider the following:

• If the Nutanix AHV backup appliance is still present in the backup infrastructure, you cannot restore its configuration to another Nutanix AHV backup appliance added to same backup infrastructure. This limitation prevents collisions between jobs with the same database ID.
• Network settings of the Nutanix AHV backup appliance remain unchanged. However, you will be able to change these settings after the configuration restore.
• Configuration settings of dedicated workers will be restored from the configuration backup, and all existing workers will be removed. If any of the settings (such as cluster, worker network settings, host affinity or storage container configuration) is invalid in the current virtual environment, a warning message will be displayed in configuration restore logs. To update worker settings, modify worker configuration after the configuration restore.
• [Applies only to the standalone cluster deployment] If you restore the configuration database of a Nutanix AHV backup appliance originally residing in another cluster to protect migrated VMs, you will need to reconfigure backup jobs. UUIDs of migrated VMs change, therefore, you will need to re-add VMs to a backup job that will start new backup chains for them.

You will also need to reconfigure backup jobs and workers, if the original appliance was configured to manage jobs in a Prism Central deployment and the new appliance is connected to a standalone cluster.

• [Applies only to the Prism Central deployment] If you restore the configuration database of a Nutanix AHV backup appliance originally residing in another cluster registered with the same Prism Central, Veeam Backup for Nutanix AHV will update backup jobs and worker configuration automatically.

To restore the configuration database, do the following:

1. Launch the Configuration Restore wizard.
2. Choose a backup file.
3. Review the backup file information.
4. Provide the encryption password.
5. Choose restore options.
6. Specify credentials for the backup appliance account.
7. Track the restore progress.
8. Finish working with the wizard.
