Azure Backup: Upgrade to TLS 1.2 or above for secure MARS agent backups by September 1, 2021
Published date: 07 June, 2021
As a part of Azure-wide initiative towards using TLS 1.2 by default and removing dependencies on older versions, the Azure Backup service is working towards shifting away from legacy protocols to ensure improved security for your backup data. Hence, older versions like TLS 1.0 and TLS 1.1 will no longer be supported. These changes are expected to take effect on September 1, 2021.
In order to continue using Azure Backup without any interruptions, please ensure all resources using the Microsoft Azure Recovery Services (MARS) agent are enabled to use TLS 1.2 or above. Please refer to the steps documented in our public documentation to take appropriate action to make sure your server configuration does not force use of legacy protocols.
