About system updates

The updates interface provides a means for updating software on the system and for pushing agent updates to certain clients. This section describes system updates. For agent updates, see Push installing agent updates.

It is recommended that you run the latest Unitrends version on your backup system. When updates are available, you see an alert on the front Status page. Before updating the system, note the following requirements:

• When using an on-premise backup system that replicates to an off-premise target, the off-premise target system must first be upgraded.
• If an on-premise backup system is being remotely managed by another Unitrends system, the managing system must first be upgraded.
• To install updates, the system must be running Linux CentOS Release 5 or CentOS Release 6.
• If a restore is needed for a specific backup while a database migration is active, select the backup for migration to begin on the specific backup.
• An active support contract is required to upgrade the system.
• Updates to backup systems are compatible with older agent versions. Although it is recommended that you upgrade to the latest agent versions, the system will continue to function properly running older agents.
• Do not upgrade a client’s agent software to a version newer than that of its backup system. Update the backup system prior to installing newer agents. The backup system version must be equal to, or newer than, that of its clients.
• To update a physical appliance that cannot connect to the Internet, you can use an ISO image and follow the instructions in KB 2483.
• If you are running a pre-6.0 version, contact Support for assistance in upgrading.
• For more information about upgrading to the current version, see the Upgrade Guide for Recovery Series and Unitrends Backup - Legacy Interface.
ClosedTo update the system
1 Select Settings > System, Updates, and Licensing > Updates.
2 Look at the message on the System Updates tab and do one of the following:
• If you see the message The system is up to date, there are no updates to install. Click Exit to close and do not continue with these steps.
• If you see the message There are "x" available updates, continue with these steps.
3 To see details on the software packages that are being updated, click Show Update Details.

Packages can be selectively added or removed by dragging the packages to the right pane or the left pane respectively. Packages beginning with the word unitrends are required. It is highly recommended to install all available updates at all times.

4 Click Install to start updating software packages.

If there are software updates (like the kernel package) that require a reboot, you receive a message to this effect once the updates have been installed. If you do not receive this message, a reboot is not necessary.

During installation you see progress messages, such as installing 5 of 20. If updates seem to stall, or if you receive a message indicating that a package could not be installed, you may click Exit and then restart the update procedure.

5 After the installation, log out and refresh the browser before logging back in.
