Write short note on recovery regarding the file system in Windows 2000.
In many file systems a power breakdown at the wrong time can damage the file system data structures so severely that the entire volume is scrambled. NTFS has a variant approach to file-system robustness. In NTFS all file-system and data-structures updates are performed inside transactions. Previous to a data structure is altered, the transaction writes log records that contains redo and undo information then data structure has been changed the transaction writes a commit record to the log to signify that the transaction succeeded. Subsequent to a crash the system can restore the file system data structures to a consistent state by processing the log records first redoing the operations for the committed transactions after that undoing the operations for transactions that did not commit successfully before the crash.
