Preparing a client for restore
Review the secure communication compatibility matrix for BMR for NetBackup 8.1.1 and later releases before you proceed with the prepare to restore operation.
See Secure communication compatibility matrices for BMR for NetBackup 8.1.1 and later releases.
Before you restore a client, you must prepare to restore (PTR) the client.
During a prepare-to-restore operation, the NetBackup master server does the following:
Retrieves the client configuration from the master server database.
Creates the restore script and the configuration files that are used to restore the client.
Allocates the boot server resources for the selected client recovery.
When you prepare to restore a client, you select the configuration to use for the restore, as follows:
For a standard restore (also known as a self restore, which is a restore to the same system), select the current configuration.
For other types of restores, select the configuration that you created for the restore.
To ensure that the restore includes the most recent data, Veritas recommends that you prepare to restore immediately before you restore a system.
To prepare a client for restore using the bmrprep command
- Login as an administrator.
- Run the bpnbat command.
For more information regarding bpnbat command, refer to the NetBackup Command Reference Guide
- Run the bmrprep command to initiate a prepare to restore operation.
For more information regarding bmrprep command, refer to the NetBackup Command Reference Guide

Starting with Netbackup 8.1.1 release, when you execute the bmrprep command, validation checks are performed pertaining to the different parameters such as SRT version, configuration version, and so on.
If the validation checks for prepare to restore are successful, then the client is marked for automatic recovery. This automatic recovery is by default valid for 48 hours. Master server authenticity is validated automatically and a host-ID based certificate is automatically issued to this client during the automatic recovery process.
Use the nbhostmgmt command to verify whether the client is marked for automatic recovery.
For more information about the nbhostmgmt command, refer to the NetBackup Command Reference Guide
https://www.veritas.com/support/en_US/article.DOC5332
For more information about the automatic recovery and the host-ID based certificate, refer to the NetBackup Security and Encryption Guide
If the validation checks fail, appropriate error messages are displayed. Follow the instructions that are provided in the message.
For more information, See Error messages for prepare to restore, prepare to discover, and the bmrprep command with reference to secure communication in BMR.
The client is ready for restore.
To prepare a client for restore using the NetBackup Administration console
- In the NetBackup Administration Console, expand Bare Metal Restore Management > Hosts > Bare Metal Restore Clients.
- Select a client or a client configuration.
- Select Actions > Prepare to Restore.
- In the Prepare to Restore Client dialog box, select the appropriate values for the restore.
Some fields may be completed depending on whether you selected a client or a client configuration.
If some other PTR options are selected, See BMR disk recovery behavior.
- Click OK.
Bare Metal Restore runs all the processes to prepare for a restore.

- After the processes finish, in the dialog box that appears, click OK.
The client is listed in the Bare Metal Restore Tasks in Queued state. The Prepare-To-Restore step may take few minutes to complete.
To clean up the restore configuration
- In the NetBackup Administration Console, click Bare Metal Restore Management > Bare Metal Restore Tasks.
- In the details pane, right-click the client for which you want to clean up the restore configuration.
