Re-pairing of Windows and Linux agents

You can now use the Re-Pair button on the Configure > Protected Assets tab to establish a secure pairing between the asset and its appliance.

Re-pairing requires the asset to be in pairing mode. The 10.7.9 Windows agent includes an agent pairing utility you can use to enable pairing mode for a specified amount of time, known as the pairing window. For Linux assets, you can use the instructions in the Unitrends Agent Pairing - Linux KB article to enable pairing mode.

After enabling pairing mode on the asset, use the Re-Pair button to:

●   Add the asset to a Unitrends appliance. (For example, use to add the asset to one or more appliances after the initial 25-hour pairing window has closed.)

●    Re-establish pairing between the asset and the appliance. (For example, use if the asset's pairing status changed to Failed due to an error condition.)

●   Establish pairing between the asset and the appliance after upgrading the agent from an older version that did not support pairing.

For detailed requirements and procedures, see Secure agent pairing for Windows and Linux agents.

Copy backups to your Azure environment

Addressing customer requests, we now support copying backups to Azure blob storage. This addition provides greater flexibility in choosing cloud storage solutions to suit diverse needs. Simply add the Azure Blob storage container to your Unitrends appliance as a backup copy target, then add a job to copy backups to this container. For detailed requirements and procedures, see Backup copy targets.

Service update for backup copy to third-party cloud targets

This release includes a new backup copy format that supports Azure and more resilient S3:

●   Enhanced format for new S3 buckets – Beginning in Unitrends release 10.7.9, newly created S3 buckets will automatically adopt an improved format. This new approach enhances resilience, especially in handling service disruptions, ensuring more reliable data management.

●   No changes to existing S3 buckets – Existing S3 buckets remain unchanged, ensuring continuous operation with the bucket's existing backup copy format and no loss of retention. No user action is required for these buckets.

Security updates

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.

●   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

●   OpenSUSE 42, 64-bit

●   Oracle Linux 8.1, 64-bit

●   RHEL 7, 64-bit

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.
