To run the Beta 10.3.0 release, you can either deploy a virtual Unitrends Backup appliance by using the Beta image or upgrade an existing appliance. Upgrading to Beta release 10.3.0 is not supported for all appliances. Be sure to review the Upgrade requirements and considerations before upgrading any appliance.
See one of these topics for details:
• | Deploy the Beta Unitrends Backup appliance |
• | Upgrade a Unitrends appliance to Beta release 10.3.0 |
You can deploy the Beta Unitrends Backup appliance to the following virtual environments:
• | VMware |
• | Hyper-V |
• | Nutanix AHV |
• | Microsoft Azure |
• | Amazon Web Services |
To deploy the appliance, complete the Beta participation form. Upon completing the form, you will receive a link you can use to download the Beta image. Save the image on the machine you will use to access the hypervisor where the Unitrends Backup virtual machine will reside. See the Deploying a Unitrends Backup Appliance chapter in the applicable guide for instructions on deploying the Unitrends Beta image:
Notes: If you will be copying backups to a Unitrends appliance target, you can either:
• | Deploy a second Beta virtual appliance to use as the backup copy target. |
• | Upgrade an existing appliance to use as the backup copy target. (For details, see Upgrade a Unitrends appliance to Beta release 10.3.0.) |

Upgrade requirements and considerations
Review the following before upgrading to Beta release 10.3.0:
Requirement or consideration |
Description |
|||||||||
---|---|---|---|---|---|---|---|---|---|---|
Support contract |
An active support contract is required to upgrade the appliance. |
|||||||||
Linux CentOS version |
To upgrade to this Beta release, the appliance must be running CentOS 6. If you’re using the current HTML5-based UI, then you are on CentOS 6. To check the appliance OS version from the legacy UI, select About > System Information and look at RecoveryOS Version. Note: For information on migrating from CentOS 5 to CentOS 6, see KB 3943. |
|||||||||
Upgrading an appliance that is running a 10.2.0 Beta release for Windows Image-level protection is not supported. You must either deploy a new Unitrends Backup appliance or upgrade an appliance that is not running a 10.2.0 Beta release. After deploying with this 10.3.0 Beta release, you will be able to upgrade to subsequent Beta and production releases (without redeploying). |
||||||||||
Backup appliance that is copying backups to the Unitrends Cloud |
Important! If you are currently copying backups to the Unitrends Cloud in your production environment, do not upgrade the source backup appliance to the Beta 10.3.0 release. Copying backups to the production Unitrends Cloud is not supported for source appliances running the Beta 10.3.0 release. Backup copy to the Unitrends Cloud is supported for newly configured Beta Cloud targets only. To use this feature, contact Unitrends Support for assistance. The following requirements and considerations apply:
|
|||||||||
Backup copy target appliance |
Upgrade the backup copy target appliance before upgrading its source appliance. For backup copies, both the source and target must be running the Beta 10.3.0 release. |
|||||||||
Remotely managed appliance |
If an appliance is being remotely managed by another Unitrends appliance, the managing appliance must be upgraded first. |
|||||||||
Upgrading from a pre-10.1 release |
Consider the following before upgrading from a pre-10.1 release:
|
Use the following procedure to upgrade your Unitrends appliance to Beta release 10.3.0.
Notes:
• | Do not upgrade a production appliance that is currently copying backups to the Unitrends Cloud. Copying backups to the production Unitrends Cloud is not supported for source appliances running the Beta 10.3.0 release. See Backup appliance that is copying backups to the Unitrends Cloud for additional information. |
• | If you will be copying backups to a Unitrends appliance target, use this procedure to upgrade the target appliance before you upgrade the source backup appliance. |
• | You cannot upgrade an appliance that is running a 10.2.0 Beta release for Windows Image-level protection. Instead, deploy a new Unitrends Backup appliance (see Deploy the Beta Unitrends Backup appliance) or upgrade an appliance that is not running a 10.2.0 Beta release. |
1 | Open a Firefox or Chrome browser and connect to the appliance UI by entering: https://<applianceIPaddress>/ui/. For example: |
2 | Log in as a user with administrative privileges. |
3 | Click the gear icon and select Check for Updates. |
4 | A list of available updates displays. Click Apply Update to begin the installation. |
5 | For some appliances, software maintenance is required with the update. If so, you see this message and the update will take some extra time: |
Note: If you do not see this message, maintenance has already been performed on the appliance.
Do one of the following:
• | Click Confirm to continue with the update. |
• | Click Cancel to quit. (You can then install the update at another time.) |
6 | During the upgrade, you see status messages as packages are installed. If you have trouble with the installation, see Troubleshooting the appliance upgrade for tips. |
7 | After the installation completes, clear your browser cache, then close the browser. |
Note: If you receive a message indicating that you need to reboot the appliance to take advantage of the new kernel installed during the upgrade, you can either reboot now or reboot at a later time. If you reboot now, do the browser steps above after the appliance boots. (If you do not receive this message, the kernel was not updated and a reboot is not required.)
8 | Open the browser and log back in to continue working with your appliance. |
Troubleshooting the appliance upgrade
In rare instances, your first attempt to update the Unitrends appliance might not be successful. See the following table for a description of upgrade issues and steps you can take to resolve them:
Issue | Next steps | ||||||
---|---|---|---|---|---|---|---|
The update times out because some of the packages did not install. |
If the installation stops and you receive a message stating a package did not install successfully, in most instances you can resolve the issue by clicking the refresh arrows and attempting the update again. If necessary you can repeat this multiple times until the update completes. See KB 3402 for more information. |
||||||
The appliance is unable to download the update packages. |
The appliance cannot reach the FTP or HTTP site - If you receive a message stating that the appliance is unable to download packages, this is the most likely cause. The FTP or HTTP site might be blocked by a firewall or some other restriction might be preventing you from reaching the site. To resolve this issue, you can download the update packages from the site you are not currently using (such as downloading from the HTTP site if you are currently using the FTP site, or vice-versa). For procedures, see KB 3401. |
||||||
An error message displays stating that the managing system must be updated. |
To update the appliance, you must first update any other appliances that are managing it. Verify that any backup copy target appliance and any other managing appliances are running the latest release. Upgrade these appliances as needed. You can then upgrade any appliances that they are managing. |
||||||
No data displays in the UI after installing appliance updates. |
