Release Notes for Recovery Series, Recovery Max, ION/ION+, and Unitrends Backup 10.7.5

This document describes new features and fixes introduced in the 10.7.5 release. For upgrade instructions and considerations, reference the Upgrade Guide for Recovery Series, Recovery MAX, ION/ION+, and Unitrends Backup.

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 in the Administrator Guide for Recovery Series, Recovery MAX, ION/ION+, and Unitrends Backup.

Linux agent and support for new Linux versions

This release includes an updated Linux agent. The 10.7.5 agent is required for protection of these newly supported 64-bit Linux versions: Alma Linux 9, Debian 10, CentOS 9, Fedora 35, 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.

• 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:

– Alma Linux 9, 64-bit
– CentOS 7, 64-bit
– CentOS 9, 64-bit
– Debian 10, 64-bit
– Fedora 35, 64-bit
– OpenSUSE 42, 64-bit
– Oracle Linux 8.1, 64-bit
– RHEL 7, 64-bit
– RHEL 8.4, 64-bit
– RHEL 9, 64-bit
– Rocky Linux 9
– SLES 11 SP3, 64-bit
– SUSE 15, 64-bit
– Ubuntu 22.04, 64-bit

Windows agent

This release includes updated Windows core and bare metal agents. The 10.7.5 core agent is recommended for most 64-bit Windows assets is required for Windows fixes in this release.
Consider the following before upgrading the Windows agent:

Beginning in Windows agent release 10.6.6, a secure pairing is automatically established between the appliance and the Windows 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.

• If upgrading from a pre-10.6.9 agent release, backups may fail until the pairing completes successfully (this can take up to two hours).
  • To protect Hyper-V clusters, SQL clusters, or file server clusters with the secure agent pairing feature:
    - The cluster must be running agent version 10.6.9 or higher.
    - The Unitrends appliance and cluster must be running in the same time zone.

Fixes

The table below lists fixes included in this release. Unless stated otherwise, you can apply each fix by simply upgrading your appliance.
