If the Cloud Backup updater, described in Install or update the Cloud Backup agent on Linux® or Install the Cloud Backup agent on Windows®, failed, use the steps in this article to manually update the Rackspace Cloud Backup agent.

We release Rackspace Cloud Backup agent updates as needed. When a new agent is available, agent updates are pushed automatically by the automated updater. If the automated updater fails for some reason, follow the instructions in this article to take advantage of the latest security patches, features, and bug fixes in Cloud Backup.

Note: These instructions assume that you previously installed the agent.

Update the agent for Linux-based systems#

For Linux-based systems, you might want to review Install or update the Cloud Backup agent on Linux before performing these steps.

Use SSH to log in to your server as a user with sudo or superuser privileges.
Download the latest Linux CBU package.

Extract the package manually.

 sudo tar jxvf driveclient-latest.tar.bz2

Move the agent app to /usr/local/bin.

 sudo mv driveclient*/driveclient /usr/local/bin/. && sudo chown root:root /usr/local/bin/driveclient &&
 sudo chmod 755 /usr/local/bin/driveclient

Create an install folder and move the agent cert.

 mkdir /etc/driveclient && mv driveclient*/cacert.pem /etc/driveclient/

Register the driveclient.

 /usr/local/bin/driveclient --configure --username myuserid --apikey ${apikey} --flavor raxcloudserver --datacenter DFW

Start the driveclient.
```
 /usr/local/bin/driveclient --daemon
```

For more detailed information on these configuration settings, see Update or install the Cloud Backup agent on Linux.

Warning: This assumes that you are manually installing the agent because the current updater does not yet support the system you are installing it on. For that reason, we make no assumptions about the requirements to add the agent or the updater as a service. This means you must manually start the driveclient every time you restart the server.

Update the agent on a Windows system#

Run the steps in this section as Administrator or as a user with Administrator privileges. You might want to review Install the Cloud Backup agent on Windows before performing these steps.

Because the Windows agent includes an automated updater, you should rarely need to update the Windows agent manually. This section provides different options to use if you need to update manually.

Recommended method#

The recommended way to perform a manual update is to download the latest agent from the deployment server and simply run it.

Download the updated agent from https://agentrepo.drivesrvr.com/win64/driveclient-setup-latest.exe
Run the updated agent.
```
 driveclient-setup-latest.exe
```

You can also run the agent by simply executing the wrapper application from a Windows file browser.

Alternative method#

You can also update an existing agent from the command line with msiexec. However, using this method could adversely affect your agent registration. Attempt this method only if you know exactly what you are doing.

Save the configuration files from %PROGRAMDATA%\Driveclient.
Uninstall the current agent.
Copy the saved configuration files back to their original locations in %PROGRAMDATA%\Driveclient.
Download the latest MSI from the deployment server and run the installation without APIUSER and APIKEY.
```
 msiexec /i driveclient-1.18.007148-en-us.msi /qn /l*v %tmp%\install-1.18.007148.log DEBUGHIGH=true
```

Otherwise, updating the agent by using the MSI is the same as a fresh installation. You have all the same MSI options available. For the verification steps to test the update, see Test the Windows installation or update.
