Error Correction and Fault Tolerance
In order to increase the reliability of the file system, and hence the operating system as a whole, NTFS includes several fault tolerance features. As the name suggests, these are capabilities that improve the ability of the file system to deal with error conditions that may arise when the system is in use. Fault tolerance is very important for business applications where a primary goal is to keep systems running smoothly with a minimum of downtime.
In no particular order, here are some of the fault tolerance and error-handling features that NTFS includes. Note that some of these capabilities are implemented through the use of the NTFS fault-tolerant disk driver, called "FTDISK":
These features all help to make NTFS a reliable file system. Of course, they only protect against certain types of problems, and only in certain ways. These capabilities should certainly not be considered replacements for proper backups and other system maintenance!
