Restore Crosswork Network Controller data from a backup file to recover a cluster after data loss or other service-impacting issues.

This task describes how to perform a data restore operation from the Crosswork Network Controller UI.

The time taken for the restore process varies based on the type of backup, your cluster size, and the applications in the cluster.

Before you begin

  • Ensure you have a backup file available for restore.

  • You must install the exact build versions of the applications that were present when the backup was created. Any mismatch can result in data loss and failure of the data restore job.

Procedure

1.

Go to Administration > Backup and Restore.
2.

Select the backup file for restore:

  1. In the Backup and Restore Job Sets table, select the data backup file you want to use for the restore. The Job details panel displays information about the selected backup file.

  2. Click the Data restore button to start the restore operation.
3.

Monitor the restore progress:

The system creates a restore job set and adds it to the job list. To view the progress, click the link to the progress dashboard.

If MDT (Model-driven Telemetry) collection jobs were deleted after the backup, the restore operation will fail to recover them, leaving them in an error state due to missing device configurations. To rectify this, perform one of the following actions:

  • Restore the backup taken for external NSO (only applicable if the original backup included external NSO).

  • Move the devices associated with MDT collection DOWN and UP in Device Management.

  • Detach and attach devices to the Crosswork Data Gateway pool.

Note

In a geo-redundant setup, if external destinations are added and Data Gateway is re-enrolled after a backup, restoring the backup file may result in stale certificate expiry alarms. These alarms must be manually cleared.

The system initiates the restore operation from the selected backup file. The restore job appears in the job list with status detail.
