We're currently designing a new infrastructure based around Windows Server 2012 so I'm currently investigating all the new technologies, including whether we should format the file server drive in ReFS format - and what problems we might encounter. I'm aware that it's not a good choice for SQL due to lack of sparse files but for a plain-vanilla file system, it might be a good thing to use.
However, we currently use scheduled Shadow Copies to allow users to recover accidentally deleted/corrupt files during the day before the nightly backup kicks in. In my lab environment, I've just created two drives. One formatted as NFTS and the other formatted as ReFS.
When I look at the properties of the NTFS drive, Shadow Copies tab is there:
Including the F: drive - the ReFS drive.
However, when I bring up the properties of the F: drive, the Shadow Copies tab is missing:
So to configure shadow copies on ReFS drive, you have to select an NTFS drive and then select the ReFS volume.
A little bizarre?
