Before You Begin
Before you start the restore process, check the following prerequisites:
- Make sure the user, who initiates the backup configuration restore process, has the Debug programs policy applied. Otherwise, Veeam Backup & Replication returns the Access is Denied error. To learn how to apply the policy, see this Veeam KB article.
- Multi-factor authentication (MFA) for the user account must be disabled before launching configuration database restore wizard. To learn how to disable MFA, see Multi-Factor Authentication.
- Stop all jobs that are currently running. During restore of configuration, Veeam Backup & Replication temporary stops the Veeam Backup Service and jobs.
- Save registry values that you changed or created on the backup server. After restore, you will need to recreate or change the keys manually because the configuration database does not store them.
- Check the version of the backup server. On the backup server running Veeam Backup & Replication 12, you can restore configuration backups created with the following product versions: 11a (build 184.108.40.2061), 11 (build 220.127.116.117), and 10a (build 10.0.1.4854).
- Make sure that the certificate chain restored from a configuration backup will successfully pass validation on the target backup server. This precaution is required if the following conditions are met:
- You want to restore configuration database of a backup server used in the Veeam Agent management scenario.
- The backup server whose configuration database you want to restore uses a custom certificate issued by a Certificate Authority instead of the default self-signed certificate to ensure a secure connection in the Veeam Agent management infrastructure.
- If you plan to restore configuration data to the database on another Microsoft SQL Server, make sure the account for using Veeam Backup & Replication has sufficient permissions. For more information, see Permissions.
- You can not use Microsoft SQL Server configuration backup created in Veeam Backup & Replication 11 or earlier to restore the configuration database to PostgreSQL.
- [for Veeam Backup for Nutanix AHV users] After you restore the configuration database of Veeam Backup & Replication, you must remove existing AHV backup proxies from Veeam Backup & Replication infrastructure and connect to them again. Otherwise, these AHV backup proxies will not be able to perform backup and restore due to missing authentication certificates. For instructions on how to connect to an existing AHV backup proxy, see the Adding Nutanix AHV Backup Proxy section in the Veeam Backup for Nutanix AHV User Guide.
- After you run configuration restore for capacity tier, Veeam Backup & Replication will put the capacity tier extents into the Sealed mode. Rescan the backup infrastructure and then remove the extents from the Sealed mode.
- If you use a Veeam Backup & Replication server as a Veeam repository, after restore to a new host this repository will be located in the same file path as it was before the migration.
You can start configuration restore only from the Veeam Backup & Replication console installed locally on the backup server. You cannot start configuration restore from the console installed on a remote machine.
