Mounted drives By using mounted drives, systems administrators can map a local disk drive to an NTFS directory name. This helps them organize disk space on servers and increase manage- ability. By using mounted drives, you can mount the C:\Users directory to an actual physical disk. If that disk becomes full, you can copy all of the files to another, larger drive without changing the directory pathname or reconfiguring applications.
Remote storage Systems administrators often notice that as soon as they add more space, they must plan the next upgrade. One way to recover disk space is to move infrequently used files to tape. However, backing up and restoring these files can be quite difficult and time con- suming. Systems administrators can use the remote storage features supported by NTFS to automatically off-load seldom-used data to tape or other devices, but the files remain available to users. If a user requests an archived file, Windows Server 2008 can automatically restore the file from a remote storage device and make it available. Using remote storage like this frees up systems administrators?? time and allows them to focus on tasks other than micromanaging disk space.
Self-Healing NTFS In previous versions of the Windows Server operating system, if you had to fix a corrupted NTFS volume, you used a tool called Chkdsk.exe . The disadvantage of this tool is that the Windows Server??s availability was disrupted. If this server was your domain controller, that could stop domain logon authentication.To help protect the Windows Server 2008 NTFS filesystem, Microsoft now uses a feature called self-healing NTFS. Self-healing NTFS attempts to fix corrupted NTFS filesystems without tak- ing them offline. Self-healing NTFS allows an NTFS filesystem to be corrected without running the Chkdsk.exe utility. New features added to the NTFS kernel code allow disk inconsistencies to be corrected without system downtime.
Although the features mentioned in the previous section probably compel most systems admin- istrators to use NTFS, more reasons make using it mandatory. The most important reason is that the Active Directory data store must reside on an NTFS partition. Therefore, before you begin installing Active Directory, make sure you have at least one NTFS partition available. Also, be sure you have a reasonable amount of disk space available (at least 4GB). Because the size of the Active Directory data store will grow as you add objects to it, also be sure you have adequate space for the future.Exercise 3.1 shows you how to use the administrative tools to view and modify disk configuration.
