Backup and Restore in a Modular Architecture¶
Backups that were made before topology migration to a modular architecture can not be restored to the topology after migration. Manual intervention is required to restore.
A new modular architecture backup must be created immediately after topology migration. This backup will be on the highest priority secondary db node.
Important
Backups for an Application and Web Proxy type node are not required. A backup created on the secondary database node will include all the relevant data, excluding the web certificates.
After a restore is performed by following the documented process: Restore the Backup, the web certificates need to be reinstalled on each of the Application and Web Proxy nodes. For commands, see: Web Certificate Commands. These certificates should already be stored in a safe location after initially installed, therefore do not require inclusion in the backups.
When restoring a backup on a cluster, the latest backup from the highest weighted secondary database server must be used to ensure the entire cluster (excluding the web certificates) including the database is restored and the cluster is automatically provisioned as part of the restore.
