A file system is a special purpose database for the organization,manipulation,storage, and retrieval of data.There are many file systems in linux like ext2, ext3, ext4 .The ext3 is a journaled file system that is commonly used by the Linux kernel. It is the default file system in many popular Linux Distributions.Its main advantage over ext2 is journaling which improves reliability and eliminates the need to check the file system after an improper shutdown. Its successor is ext4.
Some brief Details about EXT3 or (third extended filesystem) File system :
1) Supported operating systems: Linux, BSD, Windows (through an IFS)
2) Maximum length of filename 254 bytes
3) Max volume size 2TiB to 16 TiB
4) File system permission: Unix permissions, ACLs and arbitrary security attributes (Linux 2.6 and later)
Advantages Of EXT3 File System
Even though its performance (speed) is less attractive than other Linux filesystems such as JFS, ReiserFS and XFS,it has some worthwhile advantage in comparison to them like it is allowing in-place upgrades from the ext2 file system without having to back up the data. Ext3 also has a better power efficiency than ReiserFS and XFS.This file system is also considered as safer than the other Linux file systems due to its relative simplicity and wider testing base
The ext3 file system adds, over its predecessor:
A Journaling file system, online file system growth and Htree indexing for larger directories. An HTree is a specialized version of a B-tree (not to be confused with the H tree fractal.Ext3 Lacks some modern filesystem features like dynamic inode allocation and extents it could be considered as disadvantages in some context but in terms of data recovery ext3 has a significant advantage over file systems with those features .
In Ext3 file system the file system metadata is all fixed, in well-known locations and due to some inherent redundancy in the data structures, ext2 and ext3 recovery are very much possible in the face of significant data corruption, where tree-based file systems may not be able to recover the data .
Disadvantages
The main disadvantage of this file system is its functionality: which is not in sync with the latest version, defregmentation: there is a lack of online defregmentation tool and the last one is that check summing s not done in Ext3 file system.
Allthough it is not quite easy to do file recovery for deleted file in ext3 file system, but the process of recovering the file is made easier by Linux data recovery software. Stellar Phoenix Linux data recovery software is Quiet user friendly and provides complete Ext3 recovery solution. Power full scanning algo is used in this software to locate all the lost files. This data recovery Linux software provides recovery from Other file systems too like Ext2 & Reiser file system
