How to perform Ext4 recovery operations in Linux

The Fourth Extended File System Or Better known as ext4 file system was released in Linux 2.6.28 is a complete journaling file system, it is a successor of Ext3 file system. Prior to this the maximum limit for data storage was 64 bit and Ext4 was developed as a sequence of the backward compatible extensions for enhancing these limit. It is undoubted the most important benefit is that it is safe to use Ext4 file system in production environment, but some times, delayed allocation may lead to data loss situations. Also,there are lot of errors associated with the users, like accidental deletion of data. In such cases, it is imperative to use Ext4 Recovery solutions to recover the lost data.

When you delete files from the Ext4 hard disk , the files remain physically intact logically file are not deleted . the deletion operations merely deletes the file system entries and file system pointers hence the OS can not locate any files at a location and it declares disk space as available. At this moment the need of Linux data recovery softwares arrives deleted files can be recovered by applying Linux Data Recovery methods.

You can easily recover deleted files from Ext4 file system volume with the help of “Extundelete” utility. The utility examines file system journals and other data to recover the lost data, using ext2fs library. This tool is based on ext3grep tool. Extundelete is able to retrieve both file name and contents of the deleted file.

Although, it is a very useful and effective tool, but it can not guarantee absolute data recovery. Moreover, Extundelete can not perform Data Recovery Linux if there is damage in the Ext4 file system Journal. In such times taking backup of the data is the most excellent way to safeguard your data against all types of data loss situations. But, if the backup not updated,or available then you may face grave situations of data loss.

At this point, it is possible to recover all your important data from Ext4 file system volume, through Ext4 Recovery Software. These are effective and powerful third-party applications, which carry out extensive scan of entire Linux hard disk to ensure perfect recovery of lost files, directories, and hard drive volumes. The software have self-explanatory and simple graphical user interface and read-only conduct for easy and safe recovery.
