Back up and restore SiteWise Edge gateways

This topic covers how to restore SiteWise Edge gateways and backup your metric data. If you are experiencing issues with a broken SiteWise Edge gateway on the same machine and need to troubleshoot the issue, please read the AWS IoT SiteWise documentation Troubleshooting SiteWise Edge gateway issues.

Note

The guidance covered in this topic is for SiteWise Edge gateways installed on AWS IoT Greengrass V2 version 2.1.0 or higher.

Daily backups of metric data

Creating a back up is important, if you would like to transfer or restore the data on a new machine. Backing up your data greatly reduces the risk of loss of operating data during a transfer or restoration process.

This section applies to gateways that use the data processing pack. For more information on the data processing pack, see Configure an asset model for data processing on SiteWise Edge.

The influxdb folder path is as follows:

Linux

/greengrass/v2/work/aws.iot.SiteWiseEdgeProcessor/influxdb

Windows

C:\greengrass\v2\work\aws.iot.SiteWiseEdgeProcessor\influxdb

We recommend that you backup the whole folder with everything underneath it.

We recommend that you periodically backup your metric data from the 1.0 SiteWise Edge to either an external hard drive or to the AWS cloud.

Restore a SiteWise Edge gateway

Before attempting to restore a SiteWise Edge gateway, ensure that all edge devices connected to the gateway are stopped or disconnected.

Use the following procedure to a restore a SiteWise Edge gateway:

1. Use the installation script downloaded when you create SiteWise Edge gateway to restore the SiteWise Edge gateway on the new machine. Read the Installing the SiteWise Edge gateway software on your local device procedure to setup the SiteWise Edge gateway.

   If you lose or cannot find the installation script, please contact AWS Customer Support.

2. Once the SiteWise Edge gateway has been installed, log into the AWS IoT Greengrass console.

3. To redeploy the components, navigate to Manage then under AWS IoT Greengrass devices select Core devices.

4. In the AWS IoT Greengrass core devices table select the core device corresponding to your SiteWise Edge gateway.

5. Once on the device page, open the Deployments tab and select your Deployment ID, this will open the Deployments page with your selected ID.

6. Once you are on the Deployments page, in the top right press the Actions button, and select the Revise option. to initiate a new deployment. Configure the deployment. If you would like to keep the deployment as it is, skip to Review and Deploy.

7. Wait for the Deployment Status to become Completed.

   Note

   It will also take a few minutes for all components on the SiteWise Edge to fully setup and running.

Restore AWS IoT SiteWise data

Use the following procedure to restore data on a new machine.

1. Copy the influxdb folder to the new machine.

2. Stop the SiteWise EdgeProcessor component, by running the following command in your terminal:

   Linux

   sudo /greengrass/v2/bin/greengrass-cli component stop -n aws.iot.SiteWiseEdgeProcessor

   Windows

   C:\greengrass\v2\bin\greengrass-cli component stop -n aws.iot.SiteWiseEdgeProcesso

3. Locate the path where you backed up your data, and run the following command:

   Linux

   sudo yes | sudo cp -rf <influxdb_backup_path> /greengrass/v2/work/aws.iot.SiteWiseEdgeProcessor/influxdb

   PowerShell

   Copy-Item -Recurse -Force <influxdb_backup_path>\* C:\greengrass\v2\work\aws.iot.SiteWiseEdgeProcessor\

   Windows

   robocopy <influxdb_backup_path> C:\greengrass\v2\work\aws.iot.SiteWiseEdgeProcessor\ /E

4. Restart the SiteWiseEdgeProcessor component:

   Linux

   sudo /greengrass/v2/bin/greengrass-cli component restart -n aws.iot.SiteWiseEdgeProcessor

   Windows

   C:\greengrass\v2\bin\greengrass-cli component restart -n aws.iot.SiteWiseEdgeProcessor

Validate successful backups and restorations

Use this procedure validate your backed-up data and SiteWise Edge gateway restorations.

Note

This procedure requires that you have installed AWS OpsHub for AWS IoT SiteWise. For more information see, Managing SiteWise Edge gateways using AWS OpsHub for AWS IoT SiteWise.

1. Open AWS OpsHub for AWS IoT SiteWise.

2. On the SiteWise Edge Gateway Settings page, check the status of each component listed in the Components table. Verify that the status color is green and the readout displays RUNNING.

3. Validate your past data on the portal dashboard to check that the past data and the new data are both properly setup. There will be a downtime between past and new data. You should except to see a duration where no data points are collected.
