Before the advent of journaling filesystems, recovery of a filesystem after a system crash often took a long time.
在日志文件系统出现之前，系统崩溃后恢复文件系统往往要耗费大量时间。
And, if you do need to do an urgent system recovery, you don't want to lose precious time finding large enough disks to restore to and then have to untangle data file systems from your mksysb backup.
而且，如果您的确需要进行紧急系统恢复，也不想将宝贵的时间都浪费在寻找系统恢复所需的足够磁盘空间以及再在mksysb备份中清理数据文件系统的过程。
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。
This scenario involves creating a copy of the AIX operating system environment to be used at a later time for recovery.
这个场景涉及创建AIX操作系统环境的拷贝，这个拷贝用于以后的恢复操作。
In the event of a system failure, transaction log recovery can apply or undo only those transactions not written to disk at the time of the failure.
在系统失败时，事务日志可以应用或取消失败时没有写入磁盘的那些事务。
