Hi, last week Microsoft has finally released the ReFS stability fixes KB4098787 (from KB4077525) for Windows Server 2016 and Windows 10 that fixes ReFS lockup problems with Veeam repositories. I wrote about the changelog a few weeks ago. Another change is that this update will be downloaded and installed automatically from Windows Update (although you can still get the standalone package from the Microsoft Update Catalog). As you may remember, the Windows Server 2016 version of the original package has been recalled due to an unrelated quality issue. But, in the known issues section of the updated article, there’s another issue around antivirus compatibility now. Could this be the reason why some users saw no improvement after installing the original patch… Although the more likely reason is lack of RAM on a repository server, as Microsoft is still working on optimizing ReFS memory pressure, and this particular fix looks to be scheduled for the April update.
