Recoverable File System
NTFS is a recoverable file system. NTFS logs I/O transactions to the file system. If the system crashes when the file system is in an inconsistent state, the file system is repaired automatically at the next system startup. The repair is done by a special version of CHKDSK called AUTOCHK. This does not mean that file content will not get corrupted. File content must be protected by application programs fault tolerance, like SQL Server transaction logging. NTFS protects the file system infrastructure, so that there are no problems like lost clusters in the FAT system. This means that there is less troubleshooting with NTFS than with the FAT file system.
NTFS maintains all of the regular FAT file attributes plus additional extended attributes. Alternate data streams can store volumes of data in the same way as regular file content.
Alternate data streams can be created and accessed with the syntax shown in the following example
ECHO HELLO >FILE.TXT:STREAMNAME
This example produces the output: HELLO
Some alternate data streams are accessible in the explorer file properties dialog.
Data backup is critical to recovering from system problems. The use of the Windows Backup program, NTBackup, to backup and restore data files is easy to understand.
The system state requires special consideration. The Windows Backup program backs up the system state as a complete unit. The system state consists of
Selective restoration of system state information is not possible because of dependencies. For example, programs depend on configuration in the Registry. If Registry files were restored to a system that had older versions of system file DLLs, the Registry contents may not be interpreted correctly.
Run the Windows Backup program and backup the System State.
