UPDATED (February 26, 2018): ReFS – Microsoft releases cumulative update 4077525!
Hi, the confirmation that beta ReFS driver version 10.0.14393.1934 fixed all issues, including from those with very large volumes. And reported are not just those repository server lockups fixed, but also a significantly improved performance of all backup operations. These were all excellent news, and got even better news in response: looks like the new ReFS driver is scheduled to be shipped in the next (February) cumulative update! So finally, the driver will become available for everyone and supported for production use. Many of IT Experts (especially Veeam) had spent much time working with Microsoft on this issue and finally, thanks to them! Customer Feedback: One of my customers found a temporary way around the problem. It has significantly increased the memory (RAM) on the target server. The result is ReFS bugs are now limited.
