Linux Data Recovery

Thousands of businesses and PC owners use a distribution of Linux for day-to-day business, and Linux data recovery has become an essential service when data loss occurs. Accidental file deletion, hard drive damage and file corruption can all lead to a need for Linux data recovery, but with advanced techniques and software, most lost files can be recovered in a matter of minutes.

Physical and software-based Linux data recovery options are available. Physical Linux data recovery involves reconstructing damaged hard drives and can cost thousands of dollars. Linux data recovery software, however, is much less expensive and can work very effectively in many situations.

A Linux data recovery program accesses a hard drive's file structure to restore lost files, including files that have been unintentionally deleted. Deleted files on a Linux file system aren't immediately overwritten; the space occupied by the files is marked by the operating system as free, and when space is needed for another file, the space is overwritten. Highly specialized Linux data recovery software effectively reverses this process, allowing deleted files to be transferred to another hard drive, flash drive or other storage medium.

Corrupted data can also be restored with Linux data recovery software. File corruption can happen due to minor hard drive issues and can make files unreadable. By locating the missing fragments of a file, Linux data recovery software rebuilds the lost information, which makes the data accessible again. After the software works to restore a file or a number of files, the data must be transferred to prevent data loss from reoccurring.

Data recovery is a specialized field, and although the best Linux products can recover data very effectively, there are some major differences between the processes of recovering data on a Linux operating system and recovering data on other operating systems.

The biggest hurdle in developing Linux data recovery software is that Linux file systems are very different from Mac OS and Windows file systems such as HFS, HFS+, NTFS and FAT32. Most Linux distributions use Ext3, although some machines still use the closely-related Ext2.

File systems are basically a way of organizing data, and if software isn't designed specifically for a file system, it won't run properly on a computer using that file system. Because of this, Linux data recovery software has to be specifically built for Ext3.

Linux data recovery also requires careful programming due to the large number of Linux distributions available. Distributions are basically different versions of an operating system, and as Linux's code is open source, it has more distributions than any other major operating system. Good Linux data recovery software can work with a wide variety of distributions, including popular distributions like Red Hat, Ubuntu and Mandriva.

Linux data recovery is necessary for a variety of reasons--businesses might lose valuable client data or personal computer users might accidentally delete a treasured photo or video. With the right Linux data recovery software, the information can be restored quickly and inexpensively.
