10.7.5 – June 9, 2023

This release includes the enhancements and fixes described below.

VMware 8.0

You can now use host-level backups to protect virtual machines hosted in vCenter 8.0 or ESXi 8.0.

For host-level protection of VMware 8.0 environments, the Unitrends appliance must be running release 10.7.5 or higher. For additional requirements, see VMware virtual machines.

Linux agent and support for new Linux versions

This release includes an updated Linux agent. This agent is required for protection of these newly supported 64-bit Linux versions: Alma Linux 9, Debian 10, CentOS 9, OpenSUSE 42, RHEL 9, Rocky Linux 9, and Ubuntu 22.04.

Automated secure pairing of Unitrends Linux agents

Beginning in Linux agent release 10.7.5, a secure pairing is automatically established between the appliance and the Linux agent on each of its protected assets. This pairing enables Transport Layer Security (TLS) to encrypt data and authenticate connections between appliances and agents. Communication between appliances and agents is only allowed if there is a matching (paired) certificate.

This feature blocks any communication with Unitrends agent software that doesn't originate from a paired appliance (think of a Bluetooth headset, if it's not paired or in pairing mode, no one else can communicate with it). This eliminates the threat of a rogue appliance running backups or code against an agent.

To use the secure pairing feature, these requirements must be met:

  The Unitrends appliance must be running release 10.7.5 or higher.

  The Linux asset must be running agent release 10.7.5 or higher.

  The Unitrends appliance version must be equal to or higher than the Linux agent version.

IMPORTANT  Be sure to upgrade your Unitrends appliance before upgrading your Linux agents.

  Jobs will fail if you attempt to protect a 10.7.5 or higher agent with an appliance that is running an older release.

  You cannot add an asset that is running a 10.7.5 or higher agent to an appliance that is running an older release. If you attempt this, you receive an error similar to: Failed to save client: Registration for client assetName failed. The Unitrends System could not connect to the Unitrends Agent on assetName. Please ensure that the Agent software is installed on assetName, the Agent service is running (if applicable), and no firewall settings are preventing access.

  The Linux agent listens for pairing requests on port 888. Ensure that port 888 is accessible on the Linux asset. For details and other port requirements, see Appliance network settings > Additional ports in the Appliance settings topic in the Administrator Guide for Recovery Series, Recovery MAX, ION/ION+, and Unitrends Backup.

  The Linux asset must be running one of these versions:

IMPORTANT  Do NOT install the 10.7.5 agent on other Linux versions that are not listed below. Instead, locate your Linux version on the Unitrends Downloads page and install the latest supported agent.

Fixes

The following table lists fixes included in this release.

Component

Fix

Appliance performance

  Fixed an issue that could result in excessive resource utilization.

Appliance security

  Disabled an unneeded process that could raise firewall security flags.

Backups

  Fixed an issue handling Windows mountpoints that could cause synthetic backups to fail.

  Fixed an issue that caused Windows image-level backups to fail with this error: The backup cannot proceed due to an unsupported configuration found in one of the disks configured on the system. This fix requires the 10.7.5 Windows agent.

Backup retention

  Fixed an issue that could result in a backup being deleted even though it was in the process of being imported or migrated during instant recovery.

Windows agent

  Fixed an issue where the agent was not installed with all necessary configuration settings in cases where the C:\PCBP directory had been manually removed or renamed prior to installation. This fix requires the 10.7.5 Windows agent.

  The agent is now called Unitrends Agent when viewing Windows processes and services. This fix requires the 10.7.5 Windows agent.

  For readability, agent logs no longer include full pathnames. This fix requires the 10.7.5 Windows agent.

Windows secure agent pairing

  Fixed an issue that resulted in excessive CPU utilization on the protected asset. This fix requires the 10.7.5 Windows agent.
