Stopping Foglight and running a backup

You use the appliance’s Console Program to stop the Management Server. After the processes stop, you use NetVault™ to back up the file system. The Database Repository is automatically backed up as part of this process.

 

IMPORTANT: Before you begin, ensure that the appliance is registered as a NetVault client. For instructions, see Setting up appliances as NetVault clients.

To stop processes and run a backup of an appliance:

1	Log in to the original appliance’s Console Program.

2	Select Advanced Options, and then Stop All Processes.

The Console Program shuts down all running processes on the appliance.

3	After the processes stop, launch the NetVault web UI and complete the following steps:

a	Create a device used for the backup as follows:

a	Click Guided Configuration, and then click Add Storage Devices.

The NetVault Storage Configuration Wizard appears in the display area.

b	Select Virtual tape library / media changer, and then click Next.

c	Select the machine that you wish to include the virtual library, and then click Next.

d	Specify the following two fields, and keep the default value for the remaining fields, and then click Next.

•	Choose the location on disk where you wish to create the new device

•	Specify the media capacity (in GiB)

b	Create and run a backup job as follows:

a	Click Guided Configuration, and then click Create backup jobs.

The Create Backup Job wizard appears in the display area.

b	In the Job Name field, specify a name for the file system backup.

c	Click Create New next to Selections. The NetVault Backup Selections wizard appears.

Expand the branch: <appliance_name>/File System/opt/quest/foglight.

d	Keep the default value for Plugin Options, Schedule, Target Storage, and Advanced Options.

e	Click Save & Submit.

A message confirms that the job was submitted successfully, and the backup begins.

To monitor the status of the backup, click Job Status under Monitoring. When the job is finished, close the Status window.

4	Return to the Console Program and restart processes on the appliance.

Restoring backups

You can restore a backup to the original appliance (where the backup was taken) or to a newly-imaged appliance. If you are restoring a backup to a newly-imaged appliance, start with Preparing a new appliance. Otherwise, skip to Restoring a backup.

 

CAUTION: Never restore a backup of one appliance onto another in-service appliance in your environment. The Foglight data that is restored on that appliance would be out of sync with the Archiver database associated with the appliance.

Preparing a new appliance

To prepare a new appliance:

1	If the new appliance does not have the Management Server, see Foglight APM on Dell™ PowerEdge™ R730 Appliance Imaging Field Guide.

2	Install the new appliance in your network and configure it as described in the Foglight APM Installation and Setup Guide.

 

NOTE: The appliance IP address and host name can be anything, that is, they do not have to be the same as the appliance where the backup was taken.

3	Enable the NetVault client on the new appliance as described in Enabling an appliance’s NetVault client.

4	Do one of the following:

•	If the new appliance has a different IP address and host name than the original appliance, register the new appliance on the NetVault server as described in Registering an appliance in NetVault.

•	If the new appliance has the same IP address and host name as the original appliance, ensure that you can connect to it from NetVault. In the NVBU Client Management window, click the appliance’s icon in the Clients list and select Check Access.

You are now ready to restore a backup on the new appliance.

Restoring a backup

You start by preparing the target appliance for a NetVault™ restore from the appliance’s Console Program. As part of this process, Foglight is shut down. Next you restore the backup from NetVault. When the restore job is complete, you restart the appliance.

 

CAUTION: Following this procedure deletes any existing configuration settings and data under /opt/quest/foglight on the appliance, and replaces it with the restored file system and Database Repository.

To restore a backup:

1	Log in to the target appliance’s Console Program.

2	Select Advanced Options, and then More Advanced Options.

3	Select Prepare for NetVault Restore.

4	On the Prepare for NetVault Restore screen, select Yes to proceed with the operation.

5	Launch the NetVault web UI and complete the following steps:

a	Click Create Restore Job.

The Create Restore Job page appears in the display area.

b	Select the backup that you want to restore, and then click Next.

c	Expand the branch and ensure /opt/quest/foglight is selected, and then click Next.

d	In the Job Name field, specify a name for the restore job.

e	Click Create New next to Selections. The Create Selection Set wizard appears.

Expand the branch: <appliance_name>/File System/opt/quest/foglight.

f	Click the Target Client tab, and select the target appliance.

g	Keep the default value for Schedule, Source Options, and Advanced Options.

h	Click Save & Submit.

A message confirms that the job was submitted successfully, and the restore begins.

To monitor the status of the restore job, click Job Status under Monitoring. When the job is finished, close the Status window.

6	Return to the Console Program, and do one of the following:

•	If the Console Program is still active, click OK to confirm an appliance restart.

•	If it timed out, log into the Console Program and select Shutdown to reboot the appliance.

7	After the appliance finishes restarting, exit the Console Program and log in to the Foglight browser interface to validate that the data has been restored.

The restore process is complete.
