Restoring Central database by using the roxctl CLI

You can use the roxctl CLI to restore Red Hat Advanced Cluster Security for Kubernetes (RHACS) by using the restore command. This command requires an API token or your administrator password.

Restoring by using an API token

You can restore the entire database of RHACS by using an API token.

Prerequisites

  • You have a RHACS backup file.

  • You have an API token with the administrator role.

  • You have installed the roxctl CLI.

Procedure

  1. Set the ROX_API_TOKEN and the ROX_ENDPOINT environment variables by running the following commands:

    $ export ROX_API_TOKEN=<api_token>
    $ export ROX_ENDPOINT=<address>:<port_number>

  2. Restore the Central database by running the following command:

    $ roxctl central db restore <backup_file> (1)
    1 For <backup_file>, specify the name of the backup file that you want to restore.

Restoring by using the administrator password

You can restore the entire database of RHACS by using your administrator password.

Prerequisites

  • You have a RHACS backup file.

  • You have the administrator password.

  • You have installed the roxctl CLI.

Procedure

  1. Set the ROX_ENDPOINT environment variable by running the following command:

    $ export ROX_ENDPOINT=<address>:<port_number>

  2. Restore the Central database by running the following command:

    $ roxctl -p <admin_password> \(1)
  central db restore <backup_file> (2)
    1 For <admin_password>, specify the administrator password.
    2 For <backup_file>, specify the name of the backup file that you want to restore.

Resuming the restore operation

If your connection is interrupted during a restore operation or you need to go offline, you can resume the restore operation.

  • If you do not have access to the machine running the resume operation, you can use the roxctl central db restore status command to check the status of an ongoing restore operation.

  • If the connection is interrupted, the roxctl CLI automatically attempts to restore a task as soon as the connection is available again. The automatic connection retries depend on the duration specified by the timeout option.

  • Use the --timeout option to specify the time in seconds, minutes or hours after which the roxctl CLI stops trying to resume a restore operation. If the option is not specified, the default timeout is 10 minutes.

  • If a restore operation gets stuck or you want to cancel it, use the roxctl central db restore cancel command to cancel a running restore operation.

  • If a restore operation is stuck, you have canceled it, or the time has expired, you can resume the previous restore by running the original command again.

  • During interruptions, RHACS caches an ongoing restore operation for 24 hours. You can resume this operation by executing the original restore command again.

  • The --timeout option only controls the client-side connection retries and has no effect on the server-side restore cache of 24 hours.

  • You cannot resume restores across Central pod restarts.

  • If a restore operation is interrupted, you must restart it within 24 hours and before restarting Central, otherwise RHACS cancels the restore operation.
