"A journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the intentions of such changes in a data structure known as a "journal", which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with a lower likelihood of becoming corrupted." - https://en.wikipedia.org/wiki/Journaling_file_system ext2 isn't a journaling file system, while ext3 and ext4 are journaling file systems.
