ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements. [4]
In Linux, the ext2, ext3, ext4, JFS, Squashfs, UBIFS, Yaffs2, ReiserFS, Reiser4, XFS, Btrfs, OrangeFS, Lustre, OCFS2 1.6, ZFS, and F2FS [11] filesystems support extended attributes (abbreviated xattr) when enabled in the kernel configuration. Any regular file or directory may have extended attributes consisting of a name and associated data.
The extended file system, or ext, was implemented in April 1992 as the first file system created specifically for the Linux kernel. Although ext is not a specific file system name, it has been succeeded by ext2, ext3, and ext4.

However, other programs, or filesystem-independent ones such as defragfs, [17] may be used to defragment an ext3 filesystem. ext4 is somewhat backward compatible with ext3, and thus has generally the same amount of support from defragmentation programs. Currently e4defrag can be used to defragment an ext4 filesystem, including online ...
ext3, or third extended filesystem, is a journaled file system that is commonly used with the Linux kernel.It used to be the default file system for many popular Linux distributions but generally has been supplanted by its successor version ext4. [3]
Therefore, Clonezilla uses a smart file system-aware approach. It uses information from the file system to determine which blocks on a drive require copying. This ensures that only the space currently in use on the drive is copied while empty space is ignored. Clonezilla supports Ext2, Ext3, Ext4, ReiserFS, XFS, JFS, Btrfs, NTFS, FAT, exFAT and ...
