An Easy Way to Recover Data From Ext3 File System Volume
An Easy Way to Recover Data From Ext3 File System Volume
The Ext3 (Third Extended) file system is an advanced journaling file system of Linux operating system. Ext3 is the default file system in various distributions of Linux operating system, such as Fedora, Debian, and Red Hat. It provides improved data integrity, easy translation, speed, and data availability. The file system offers in-place upgrade from popular Ext2 file system. However, in some situations, the Ext3 file system may come across various issues that can damage the file system and lead to data loss. In such critical situations, you need to go for Linux data recovery to extract lost data from Ext3 file system volume.
The Ext3 file system has added the following three major features to its predecessor Ext2 file system:
H-tree or hashed tree directory indexes for improved performance.
A file system journal to prevent data loss in case of system crash or improper system shutdown.
In-directory file types.
For better stability and availability of your Linux system, Ext3 file system has the following three levels of file system journaling-
1.Journal, where file contents and metadata are written before they are being actually committed to hard drive. It improves reliability of your system.
2.Writeback, where only the metadata is journaled. It is faster, however introduces risks of out-of-order writes.
3.Ordered, it is just like the Writeback, however the file contents are written forcedly into original file after associated metadata. It is a satisfactory compromise between performance and reliability.
In some critical situations, you may face the file system corruption and other related problems that lead to serious data loss and put you in need of data recovery Linux. The corruption to file system and its data structures is indicated by various strange error messages, similar to the following one-
"JBD: Failed to read block at offset 22327 JBD: IO error -5 recovering block 22327 in log e2fsck: Bad magic number in super-block while trying to re-open /dev/sda1 e2fsck: i/o manager magic bad!"
In such critical situations, you must have a complete and valid backup to restore data from. If backup is not available, Ext3 file recovery becomes essential. Recovery is best possible using advanced third-party applications.
The Linux recovery software are powerful enough to carry out in-depth scan of entire hard drive and extract all lost data from it. They come equipped with interactive user interface to offer easy recovery.
