In order to Restore a backup onto Sonar, navigate to System -> Backups. From here you can choose from the drop down menu:

  • Restore OS - This will restore the system from a "Backup OS". This will require all the services to be shut down in order to be restored.
  • Restore All - This will restore the system from a "Restore All". This will require all the services to be shut down in order to be restored. This will also take significantly longer to restore than doing a Restore OS.


You then have the option of choosing where the Backup is located in order to Restore the system. If you saved it locally, place the file path of the file where you stored it. If the backup is located on Sonar, enter in the path on Sonar of where the Restore is located (by default when a Backup OS or Backup All is taken, it is saved under the /var partition).

Clicking "Execute" will kick off the Restore.

If you like, you can view the progress by creating an SSH session via PuTTY or a similar SSH program and tailing the ssmtrace log which shows the progress of the Restore process. The command to run is:

tail -f /var/ssmtrace.log

SONAR 3.5

If you are running Sonar v3.5 or higher, you can run the restore os from the Command line via an SSH tool such as PuTTY. In the command line, run the following command

ssm -t restore_os

This will kick off the restore process. The Restore process requires you to have a backup_os.tgz file stored in the /var partition of the Sonar itself. If one is not there, the Restore process cannot proceed.
