responsible for managing and tracking all of this data. The Windows Server 2012 R2 plat-
form supports two file systems:
■ Windows NT File System (NTFS)
■ Resilient File System (ReFS)
Although ReFS was new to Windows Server 2012, NTFS has been around for many
years, and NTFS in Windows Server 2012 R2 has been improved for better performance.
If you have been working with servers for many years, you may have noticed a few
changes to the server file system choices. For example, in Windows Server 2003, you could
choose between FAT, FAT32, and NTFS. In Windows Server 2008 R2, you could choose
between FAT32 and NTFS. In Windows Server 2012 R2, you will notice that all versions
of FAT have been removed (see Figure 3.1).

Resilient File System (ReFS)

Windows Server 2012 R2 now includes a new file system called Resilient File System
(ReFS) . ReFS was created to help Windows Server 2012 R2 maximize the availability of
data and online operation. ReFS allows the Windows Server 2012 R2 system to continue to
function despite some errors that would normally cause data to be lost or the system to go
down. ReFS uses data integrity to protect your data from errors and also to make sure that
all of your important data is online when that data is needed.
