Managing Configuration Database
You can back up and restore the configuration database that Veeam Backup & Replication uses. If the backup server fails for some reason, you can re-install the backup server and quickly restore its configuration from the configuration backup. You can also use configuration backups to apply the configuration of one backup server to another backup server in the backup infrastructure. During configuration backup, Veeam Backup & Replication exports data from the configuration database and saves it to a backup file in the backup repository.
If you use cloud plug-ins to protect VMs in Google Cloud, AWS and other environments, you can also back up configurations of cloud backup appliances. To back up the configurations, you must enable encryption as described in section Creating Encrypted Configuration Backups.
For more information on appliance configuration backup and restore, see the following guides:
It is recommended that you regularly perform configuration backup for every backup server in the backup infrastructure. Periodic configuration backups reduce the risk of data loss and minimize the administrative overhead if any problem with backup servers occurs.
If you have a hardened repository in your backup infrastructure, you must enable data encryption for configuration backup. Otherwise, you cannot perform configuration backups. For more information, see Creating Encrypted Configuration Backups.
Do not back up the backup server configuration using backup jobs in Veeam Backup & Replication. For backup, Veeam Backup & Replication uses VM snapshots. During snapshot creation and commit, the VM freezes for some time, which can potentially lead to the following consequences:
- Disconnection from the configuration database. For more information, see the Veeam KB1681 article.
- Disconnection from remote Veeam Backup & Replication agents.
- Disconnection from network storage (for example, storage presented through iSCSI) and so on.
For this reason, you must always use the configuration backup functionality to back up and restore configuration of the backup server.
