Journaling File System

Journaling File System

A journaling file system is a file system that keeps track of the changes that will be made in a journal (usually a circular log in a dedicated area of the file system) before committing them to the main file system. In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted.

Famous quotes containing the words file and/or system:

    While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.
    Barbara Howar (b. 1934)

    Some rough political choices lie ahead. Should affirmative action be retained? Should preference be given to people on the basis of income rather than race? Should the system be—and can it be—scrapped altogether?
    David K. Shipler (b. 1942)
