Linux Data Recovery after Resizing and Defragmenting

Saving important data on the Linux supported systems has become like a trend. But in few cases after saving lots of data on the Linux volumes, you realize that these volumes are not of optimum size. Like the example, you have enough room in /usr but not in /home.

The solution of this problem exists repartitioning or resizing the hard drive for different sized volumes. But this is necessary that you backup all your data first, so as not to fall for Linux data recovery. The way to result this is to use the partition resizer which is available for different Linux file systems.

Linux Hard Drive Errors and Linux Data Recovery

Linux is the most popular and widely accepted computer operating system that is used on both desktop and server computers. Several organizations consider Linux as the most reliable and stable operating system and stores a vast amount of data on the Linux based systems.

Linux hard drive can store all kinds of data ranging from applications to text files and partitioned using either Ext2, Ext3 or ReiserFS file system. Linux file systems use physical journaling and provides better scalability as compared to other computer operating systems.

But no operating system or computer is completely fool proof and the errors can occur in Linux systems also. Sometimes, you may find it difficult to access data from the Linux systems and may get some sort of hard drive related errors when you use fsck command. You may get the error messages stating:
“/dev/hda3: Super block last mount time is in the future”
Or

“/dev/hda3: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY”
These error messages occur every time when you boot your system to try to open any Linux hard drive volume. After these error messages, you can’t access the data stored on particular volume.

These error messages can occur due to the file system errors or volume corruption. File system errors or volume corruption could be the result of virus attack, unexpected system shutdown, operating system malfunction and many others.
No matter what is the reason of the trouble, it is very important to save your data. The data stored on your hard drive is at stake of loss and you need to use some solutions as quickly as possible to save it.

Data is the lifeblood of any organization and losing it is not accepted at any cost. Data loss can destroy your business and can possibly put you out of the business. It can financially harm the organization. Thus, it is very important to recover your data for smooth running of your business.

Data recovery in such circumstances can be carried out using data recovery software known as Linux data recovery software. These software are fairly easy to use and the data recovery Linux can be done by user itself without having any sound technical knowledge.

A systematic and complete scan of the hard drive is mandatory to ensure absolute data recovery. Thus, you should always select a powerful and advanced data recovery Linux software to get all of your data back.

Data Recovery from Crashed Linux System

A disk that contains a Linux kernel which can be booted is known as Boot Disk. This disk can be used to boot the kernel, which then might load a root file system to any other disk. The Kernel on the Boot Disk generally should be told where to find the root file system.

You can say that a boot disk contains everything that is required to boot a Linux based computer. The benefit of this kind of disk is that it is compact- anything required is stored on a single disk. It is mainly beneficial in case of a system crash where you can boot the system through Boot Disk and can save your data to other location.

There are some unfortunate situations where your Linux operating system crashes and you don’t have a boot disk to boot the system. The only way out that can solve you problem in this case remains is the reinstallation of the operating system.
But it is not a safe way as it needs the hard drive formatting and wipes all of the data stored on the hard drive. It causes the nightmare of the data loss can puts you in serious problem. If the data is of great importance then create hazards for your business also.

‘Read Only File System’ Error in Linux

“Read-only file system”, this error message may appear on your screen of Linux based system which has been using dual boot procedure with Windows like operating system. When you try to mount the Linux partition, all may set well except the flash of the stated error message at the end of boot. The result of this is that you can’t do any modification or writing to your files and the system may also freeze forcing you to restart the system using hard boot.

This may create havoc for the users and the most relevant thing which the user thinks about is the data. This may create a thought in the user’s mind that whether he/she would need Linux recovery or not. So for finding out this, you need to know the reason for the same. Well the reason for this error message may be any one like:

•    File system corruption
•    Incorrect unlock addresses for an LPC flash chip
•    Disk failure

In case of disk failure, to prevent the hard disk from further harm, the file system is re-mounted as read only. This is an automatic case. For the detection and solution, you can try out the mentioned things:

Document Mangling in Linux

In computing terms the word mangling means the rewriting the file again if it is incompatible at the operating system level. In the operating system like Linux when you see that the document is mangled up then this may be due to some serious bug in it. This happens mainly at the networked systems. If the file names contain colons or backslashes then the operating system can take it other ways and can generate errors.

If the operating system like Linux gets failed then you left with no other option then to reinstall it. But if the Word processor has some bug in it then the system would not crash at all but this bug can lead your system at the stage of data loss which is irretrievable. This condition certainly requires Linux data recovery.

The Road to Linux

Linux operating system is the name given to the computer operating system which is Unix-like. This operating system has been designed for general use on the desktops, laptops and servers. But it is now being used for several of the purposes due to its advanced features like computer architecture support, stability, security, embedded systems, targeting of specific user groups and lots many.

Other of the uses are as listed below:
•    Internet is widely used by almost all of the users for collecting information and for lots other works. So in the present situation where more and more reliability and security is required at the server level, Linux operating system is now used as server operating system. This is due to its more stability and long uptime, and the fact that desktop software with a GUI is often unneeded, this has risen prominence in this area.

Blocks in Linux

The Linux based computer systems bank on Ext2, Ext3 and Reiser FS file systems. These file systems stores the data in the form of Data Blocks. Blocks are used to decrease the chances of internal fragmentation and decrease disk seeks time when reading or writing a large amount of data on the disk. Each data block group consists of a super block, an Inode bitmap, subsequently the actual data blocks.

The super block of your Linux operating system stores significant booting information. The group descriptor holds the value of block bitmap, Inode bitmap and the starting of the Inode table for each block group.  This data structure of the Linux operating system not only reduces the disk fragmentation but also make the data storage very simple.
Sometimes you may find that your Linux system responds very slowly. It might possible that the system crashes, hangs, and freezes. Such situations occur if there is a lost of fragmentation on the hard disk. The disk fragmentation can occur in case if you are using blocks also.

Data Recovery in Linux Using Ext3grep

It happens to everybody sooner or later, a single second after you press Enter you understand your mistake, but it is too late; you just removed a precious file or folder from your Linux computer for which no back up exists. Or may be you’ve back up, but it is one month old. And in shock you see the precedent month flash before your eyes as you understand in pain what you will have to do all over again.

Luckily, you bear in mind that files and folders are never in fact deleted, at most overwritten by new data. Therefore, you remount the drive read only as soon as possible. There are several methods to manually or automatically recovering the lost data. Almost all of the operating systems contain some or other undelete tools or methods.

Automated Linux Recovery Using System Imager

Recovering systems is one of the most time-consuming processes for a computer user or IT department. Imaging tools or software programs, open source and commercial, makes compressed images of the hard drive data of your computer system and stores it on a central server. Later these images can be used to restore your system or roll out new ones.
System Imager is the useful and popular open source imaging software used in Linux and other Unix based computers.
System Imager has several benefits over traditional drive imaging methods and tools. It uses rsync to store the image remotely, and can do the backup or full install in just a few minutes.

Linux Data Recovery

Linux is a Unix-like computer operating system. It is one of the most well-known examples of open source development and free software. In Linux operating system, generally all fundamental source code can be modified, redistributed and used freely by anyone.

The name “Linux” derives from the Linux Kernel, started by Linus Torvalds in 1991. The libraries and utilities of a Linux system come from the GNU (a free computer operating system) announced by Richard Stallman in 1983. The GNU part is the basis for the optional name GNU/Linux.

Predominantly acknowledged for its use on Server computers, Linux is supported by several corporations like HP, IBM, Dell, Novell, Red Hat, Oracle Corporation, and Sun Microsystems. Linux is used as an operating system for a number of computer hardware, such as desktop computers, servers, laptops, super computers and so on.

As well as Linux operating system was designed for general purpose use on servers and desktops, distributions may be specialized for various purposes such as computer architecture support, stability, embedded systems, localization and security to a specific constituency or language, support for real time applications, and assurance to a known desktop environment.

Linux is the most widely ported computer operating system. Today, more than three hundred distributions (flavors) of the Linux are available in the market. These flavors are known for their reliability, stability, data security and data safety. The data stored on Linux computers are safer than other computer operating system.

Although, Linux computers are known for their reliability and stability, but there is nothing that can be said 100% safe and secure. Like other operating systems, Linux can also fail and problems can occur with Linux systems also and the data stored on Linux hard drive may get lost. Data loss is the most drastic situation for a computer user where he/she loses the business in the form of data.

But there is no need to panic. With the advanced technologies, the recovery of lost data is possible with the help of data recovery software. Data recovery software are specially designed tools that can be used in all situations of data loss. The Linux recovery software provide an easy and simple user interface so that you can perform recovery by yourself without having any sound technical knowledge.
