Development continues on this next generation; given its heritage, it will be the next generation in Linux journaling file systems.
下一代系统的开发将继续致力于此；辅之以上一代的优势，它就会是下一代的Linux日志文件系统。
Being based on ext2fs, it lacks some of the more recent advanced features found in other journaling file systems (such as extents).
它是在ext2fs的基础上开发的，因此缺少一些其他日志文件系统所具备的高级特性(例如分区)。
XFS is one of the other early journaling file systems that was originally developed by Silicon Graphics for the IRIX operating system in 1995.

If you need to recover your data, you have to use the dreaded FSCK, which has been pretty much banished from memory since journaling file systems.
如果您需要恢复您的数据，那么您必须使用讨厌的fsck，在日记记录文件系统出现以后，几乎已经很少使用这个工具了。
Additionally, the crash recovery time for journaling file systems is dramatically reduced compared to more traditional file system methods (such as those that rely on FSCK).
另外，与较传统的文件系统方法(比如那些依赖于fsck的系统)相比，日志文件系统大大地缩短了系统崩溃的恢复时间。
Journaling file systems use a journal to buffer changes to the file system (which is also used in crash recovery) but can use different strategies for when and what is journaled.
日志文件系统是使用日志来缓冲文件系统的修改(同时也可以应用于紧急故障恢复)的，但可以根据记录的时间与内容采取不同的策略。
To sum up, journaling file systems are fault-resilient file systems that use a journal to log changes before they're committed to the file system to avoid metadata corruption (see Figure 1).
总之，日志文件系统就是一种具有故障恢复能力的文件系统，它利用日志来记录尚未提交到文件系统的修改，以防止元数据破坏(请参见图1)。

Let's take a short walk through journaling file system history, and then review the file systems available and how they differ.
下面就让我们一起简短回顾一下日志文件系统的历史，然后再看一看现行的几种文件系统，看看它们之间有什么区别。
This example shows ext3, but the Journaling flash File system version 2 (JFFS2) and SquashFS are also good choices, particularly for flash-based storage systems.
这个示例使用ext3，但是JournalingFlashFileSystemversion2 (JFFS2)和SquashFS也是合适的选择，尤其是对于基于闪存的存储系统。
