This document describes new features and fixes introduced in the 10.5.6 release. For upgrade instructions and considerations, reference the Upgrade Guide for Recovery Series and Unitrends Backup.




Windows agent

This release includes updated Windows core and bare metal agents. The 10.5.6 core agent is recommended for all Windows assets and is required for Windows fixes in this release.


IMPORTANT! Windows image-level backups – After upgrading from a pre-10.4.9 agent, the next backup is automatically promoted to a full.



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

  • Resolved an issue that prevented active directory users from logging in to the appliance after upgrading to release 10.5.5.
  • Resolved a timeout issue that could prevent certain appliances from restarting.
  • Resolved an issue with encryption passphrases containing more than 127 characters. The issue could cause these errors, even though the passphrase had already been entered and saved: Passphrase must be specified or Error: request body only required, allowed for passphrase.

  • Resolved an issue with certain CentOS 6 appliances where hot backup copy jobs were not added to the queue upon upgrading the appliance.
