journaling file system

A file system that contains its own recovery capability in the event of a failure. Before the disk indexes are updated, the information about the changes is recorded in a separate log (the journal). If a power or other system failure corrupts the indexes as they are being rewritten, the operating system can use the log to repair them when the computer is restarted.
