We have a Server 2016 Veeam 9.5 U2 server with ReFS x64 backup repository and we are backing up a Server 2016 file server with a ReFS D: drive.
When we do a restore whether it be a Guest File or a Instant VM recovery it does not see the D: drive. It sees the C: drive which is NTFS no problem.
Now what is interesting is if we create a new backup job or do a VeeamZip we are able to restore from the Full backup but once we do an incremental backup we are unable to see the D: drive again. During an incremental backup job it sees and backs up data on that D: drive.
Not sure if anyone has started moving any of their production servers to ReFS drives yet but this has me a bit concerned. I will probably be migrating the customers data back to a NTFS drive this weekend.
