1 Introduction

This document describes how to restore a backup.

1.1 Prerequisites

This section describes the prerequisites, which must be fulfilled before using the procedure.

1.1.1 Conditions

The following conditions must apply:

No other backup operation is in progress.
A backup to restore is available in the system.
The name and path of the backup to restore is known.
An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

2 Procedure

To restore a backup:

Navigate to the BrmBackupManager managed object, for example:
>dn ManagedElement=NODE06ST,SystemFunctions=1,BrM=1,BrmBackupManager=SYSTEM_DATA
Specify the backup to restore, for example:
(BrmBackupManager=SYSTEM_DATA)>BrmBackup=PERF_BACKUP_NAME1_20140428_175907
Start the restore operation:
(BrmBackup=PERF_BACKUP_NAME1_20140428_175907)>restore

The system returns output true or false.

Attention!
Risk of system malfunction or traffic disturbance.

A cluster reboot is automatically triggered when restoring a System Data backup. The resulting in-service performance impact corresponds to the time required for a cluster to restart after reboot.

Verify that the backup was successfully restored, for example:

(BrmBackup=PERF_BACKUP_NAME1_20140428_175907>)show -v

The following is an example output:

BrmBackup=PERF_BACKUP_NAME1_20140428_175907

Note:: When performing a System Data backup restore, the restore progress can be monitored (refer to View Progress Report) until the system reboot is triggered. After the system is rebooted, the progress report is reset to default values.
