Release Notes for Recovery Series, Recovery Max, ION/ION+, and Unitrends Backup 10.7.2

This document describes new features and fixes introduced in the 10.7.2 release. For upgrade instructions and considerations, reference the Upgrade Guide for Recovery Series, Recovery MAX, ION/ION+, and Unitrends Backup.


To install kernel updates, rebooting the Unitrends appliance is required upon upgrading to this release.

Windows bare metal recovery – Updated the Windows Preinstallation Environment (PE) used to create bare metal recovery media.

Windows agent push installation – Push installation is now supported for these OS versions only:

For other OS versions, download the applicable Windows agent from the Unitrends Downloads page and install it manually.

Security updates – Applied appliance security updates.


Windows agent

This release includes updated Windows core and bare metal agents. The 10.7.2 core agent is recommended for most Windows assets and is required for Windows fixes in this release.

Consider the following before upgrading the Windows agent:


For additional agent requirements, see Installing or upgrading the Windows agent in the Upgrade Guide for Recovery Series, Recovery MAX, ION/ION+, and Unitrends Backup.

  • Secure agent pairing – 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).
  • Cluster requirements –

    • 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.
