Performing Configuration Backup and Restore

In this article

You can back up and restore the configuration database that Veeam Backup & Replication uses.

During configuration backup, Veeam Backup & Replication exports data from the configuration database and saves it to a backup file in the backup repository. 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.

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.

You must 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 https://www.veeam.com/kb1681.
Disconnection from remote Veeam Backup & Replication agents.
Disconnection from network storages (for example, storages presented via iSCSI).
And other.

For this reason, you must always use the configuration backup functionality to back up and restore configuration of the backup server.
