In some users' environments, it may also cause the Windows GLR servers or proxies to reboot during the browse attempt.

The Avamar GLR plugins for Hyper-V, Exchange, SharePoint, and SQL (TLR) have an embedded third-party driver "ELDOS driver."

This component is necessary to mount the Avamar backup path of a database to accomplish the GLR or TLR operations later completed with the Itempoint tool.

That ELDOS driver is at an earlier version that does not have the latest enhancements to support newer Windows operating systems (Windows 2022 and later). This causes the failures mentioned above.

As a consequence, the GLR or TLR recovery is not supported for Windows 2022 and later, also reflected in the Avamar Support Matrix.

Dell Engineering and Product Management Teams are assessing alternatives for the best viable options.
