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.
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.

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 ...
Allocate-on-flush (also called delayed allocation) is a file system feature implemented in HFS+, [1] XFS, Reiser4, ZFS, Btrfs, and ext4. [2] The feature also closely resembles an older technique that Berkeley's UFS called "block reallocation".

Although ext is not a specific file system name, it has been succeeded by ext2, ext3, and ext4. It has metadata structure inspired by traditional Unix filesystem principles, and was designed by Rémy Card to overcome certain limitations of the MINIX file system.
Former Google CEO Eric Schmidt says human-directed AI-controlled drones are the future of war. Schmidt's startup, White Stork, is developing drones for Ukraine to use in its war with Russia.
The client itself is a lightweight kernel module that does not require any kernel patches. The servers run on top of an existing local file system. There are no restrictions to the type of underlying file system as long as it supports POSIX; recommendations are to use ext4 for the metadata servers and XFS for the storage servers. Both servers ...
