A logical journal stores only changes to file metadata in the journal, and trades fault tolerance for substantially better write performance. [9] A file system with a logical journal still recovers quickly after a crash, but may allow unjournaled file data and journaled metadata to fall out of sync with each other, causing data corruption.
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.

Paragon's NTFS driver (see below) has been merged into kernel version 5.15, and it supports read/write on normal, compressed and sparse files, as well as journal replaying. [ 40 ] NTFS-3G is a free GPL -licensed FUSE implementation of NTFS that was initially developed as a Linux kernel driver by Szabolcs Szakacsits.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
Journaling may refer to: Electronic message journaling , tracking and retention of electronic communications Journaling file system , a technique in computer file systems to prevent corruption
The Eckert-Mauchly is known as the computer architecture community's highest award. 2012 B. Ramakrishna Rau Award given by The IEEE Computer Society for the development of trace scheduling compilation and pioneering work in VLIW (Very Long Instruction Word) architectures .
For real-time journaling, the journal message is sent for further processing at the same time the actual electronic message is being sent. For periodic journaling, the journal message is stored in a secure, local storage area before being archived at the enterprise level on a periodic basis, typically after business hours.
