Linux Data Recovery Software One stop Solutions for Linux recovery Problems

In the present world data plays a very important role and Computers are important part of day to day functions of companies. It helps save lot of time and other resources. A huge amount of Data can be stored in a single drive and when security of data from illegitimate users and viruses are top most priority then Linux OS comes into fray, but some times data stored is lost due to some uncontrollable reasons.

Linux is generally used in multi-user system, its processes includes writing to disk any amount of information and at any time and for successful data recovery operation it is very important not to write anything on the affected drive, if the data is overwritten then the chances of recovery becomes minimal.

Another thing that make recovery operation extremely difficult is that when undelete operations are done Linux behave quiet differently in comparison with other Operating systems .

Under Linux the procedure typically involves

1)Unmounting the file system
2)Finding the data blocks on the raw device
3)Manually copying the blocks to another partition.

All This requires a fair degree of knowledge of how the file system in Linux works. It is therefore imperative with Linux, to take a backups before starting.

When the hard disk has only one boot able partition which is 'gone', or your operating system files are missing or corrupted,the computer will not boot normally In common with all other operating systems,The same thing happens in Linux . In this situation what you have to do is to install the drive in other computer preferably running the same operating system and the data is retrieved and after doing all these thing if the file is still inaccessible, then you will need to use the data recovery software.The Linux recovery software is the best solution in this case.

This Linux recovery software should have the most powerful scanning algorithms to scan the affected hard drive thoroughly so as to recover all the data and It should be interactive and easy to use.

The Linux data recovery software from Stellar has all these features and it works on all favors of Linux like SUSE, Ubuntu, Linspire, Debian,Red Hat and this Linux recovery software is also capable of recovering lost data from hard drives partitioned on Ext4 Ext2, Ext3 and ReiserFS file systems.

Data Recovery from Crashed Linux System

In Linux operating Systems we can boot the kernel using a Boot Disk,We can otherwise say that boot disk contains everything that is required to boot a System based upon Linux Operating System. The main thing about this disk is that it is compact and all the required data can be stored into a single disk. It is mainly beneficial in the event of crashing down of a system Now what will you do in that situation you just have boot the system using Boot Disk and can save your data to other location.

Now what will you do in the situation when your system get crashed and you don't have the boot disk to boot the system. In that case the only Option Left with you is to reinstall the entire Operating systems but that option has to be last option because during the course of installing the OS you need to format the hard drive and formatting the drive means wiping all the data. This leads to you in serious problem since It results in loss of your important data and If the data is of great importance then it will create problems for your business also.

So, what are options left with you? The way forward is to use best Linux data recovery software and recover all the data and save it to another hard drive or and then format the hard disk.

Linux data recovery software is the data recovery Linux solutions to recover all of your data from the hard drive. This software is very User friendly and easy to use and any one can perform the whole process of data recovery Linux by himself. This software has a very efficient scanning algorithms for extracting the lost data and recovering it.

The Whole Process involved is listed below step by step

1) Install Linux data recovery software on any other system

2) Attach your hard drive to it and perform scan

3) Now select the drive where all your lost data exist and start scanning it

Some of the qualities of Good Data recovery software that should be kept in mind before start recovering It should be powerful, supportive for your file system, easy to use and one important thing is that It should be easily installed and run on the windows OS There are lot of companies that are in the Data recovery software market but not all the software are worthwhile.

How to Recover Deleted Linux File

Linux is slowly but steadily becoming one of the most popular operating system. The main thing that differentiate Linux from other popular operating systems is that Linux is an open source software. This makes it free for all and it can be changed to improve the software and redistribute it. It was first launched by Linux Trovalds in the year 1991. The libraries and utilities of Linux system are incorporated from GNU. GNU is a computer operating system entirely made up of free software and was first publicly announced on September 27, 1983 by Richard Stallman.

Linux has been adopted and used as a server platform by many multinational corporations like HP, Dell, IBM Oracle and so on . Its use has grown tremendously in both offices and home. It is very important to take backup of all your important data because it becomes very difficult for a person to recover data that has been deleted .

Below is the step by step method of recovering the lost data

• Determine the partition where the lost data was located.

• Use "unmount" command to unmount the current directory.

If the file was located in the root directory then the hard drive has to be run from other system having Linux operating system .

• Use "debugfs" to repair errors and bug.

Now the problem might have been corrected and that Includes the file system where the lost files are located:

• Use "debugfs usr/abc" to a access the usr/abc directory.
  

• Now "lsdel” command is used to recover all the files that have been deleted on the file system.

And if the deleted files are not recovered after doing all the things the data can be recovered using Linux data recovery software. The Linux recovery software is a very powerful and a user friendly software that can help in all cases of data loss.

And if we talk about the best data recovery software for Linux then Stellar Phoenix Linux data recovery software first comes into our mind it is the most effective and robust data recovery software available in the market, it can be used to recover Linux hard drive volumes and data. This software employs the most powerful data recovery algorithms to find lost volumes.

Lost Important data: Use Linux Data recovery software

Computer has made our life very simple. We can store lot of data in our systems and save a lot of paper work but some times this dependency can be a big cause of worry since we often don't take back up of our data and we finds ourselves in a helpless condition, when some problem occurs with our hard disk in that time data recovery is the only option left with us Recovering data from Linux is very problematic since Linux is generally used as a multi-user system, and the processes writes data to the disk at any location with any amount of information.

As it is essential in data loss situations to not write anything to the affected drive, this can complicate the matters and the likelihood of a successful recovery decreases with that.

Another thing that differentiate linux with other Operating systems is that it does not behave like other OS when undelete operations comes into force. In case of Linux the procedure typically involves-

1) Unmounting the file system
2) Finding the data blocks on the raw device,
3) Manually copying the blocks to another partition.

All these processes requires a fair degree of knowledge about the working of files systems. It is therefore imperative with Linux, as it is with other OS, to keep backup.

In common with all other operating system, A computer will fail to boot if the hard disk of PC has just one partition and the partition is corrupted or some of its important files goes missing . In that situation the drive is installed in another system which is familiar with the file system and same OS is installed in the Machine .If the file system is still not accessible, then the need of Data recovery software arises.

Stellar Phoenix Linux data recovery software is a software that deals with all these data recovery related issues in Linux Operating system. This software has the most powerful scanning algorithms it scans the affected hard drive thoroughly and retrieve all the lost data. This data Linux recovery software has a very user friendly Graphical User Interface which makes it interactive and very easy to use. The software supports all Linux OS such as Debian, Ubuntu, Red Hat, SUSE, Linspire, and many more. It is also capable of recovering data from all type of file systems like Ext2, Ext3 and ReiserFS .

Understanding the file system EXT3 in linux

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
