ext2 and ext3
In 1993, ext2 was introduced with enhancements, including the traditional Unix inode and features from the Unix File System (see UFS). Volume size was greatly increased to 32TB.
Introduced in 2001, the major enhancement to ext3 was three levels of journaling, the most robust of which duplicates the indexes and file contents in the journal before updating the actual file system (see journaling file system). See file system.
