Data Loss in Linux after Doing Apt-get Upgrade

The Operating system is the most essential part of a computer system. Operating system vendors periodically release updates to increase their performance and add new functions. In Ubuntu Linux you can use apt-get for complete up-gradation.

Apt-get is a powerful command line utility, which is used to communicate with Advanced Packaging Tool (APT) of Ubuntu. It performs installation of new application packages, updates package list index and upgrade existing software packages. It can even upgrade the core Ubuntu operating system files.

Apt-get upgrade checks all software packages in system and then checks those software packages that could be upgraded without uninstalling or affecting anything in the operating system. Then it installs the upgrades. Ultimately you have a fully upgraded Linux system and the software packages that could not upgrade automatically.

Being a straightforward command line utility, apt-get has a number of benefits over other application package management tools vailable for Ubuntu server administrators. Some of the key benefits of this upgrade include:

Ease of use as compared to the Simple Terminal Connections (SSH)

Compatible with system administration scripts

Automated upgrade using the cron (short for chronograph) scheduling tool

Although, apt-get is an extremely useful tool for Ubuntu up-gradation, but sometimes it may lead to problems. After apt-get upgrade, you may get potential fsck errors on the Linux workstation during startup. The boot process may get halted. Also there is a possibility that you see the system dump in shell with the error:

"/dev/hda3: Super block last mount time is in the future

/dev/hda3: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY"

This behavior of Linux could be the possible result of damage to the file system or errors in the MBR (Master Boot Record). Due to the same, Linux does not get complete boot information and shows the above error message.

The ultimate result of this problem would be the loss of your valuable data. To overcome this problem, you need to performLinux Recovery.

The Data Recovery Linux is best possible with the help of Linux Recovery software. These tools are capable of systematically scanning your hard drive and extracting lost data towards absolute recovery. To ensure safe, easy and complete recovery, you need to have a quality recovery tool.

Stellar Phoenix Linux Data Recovery is powerful Linux Recovery software. It supports ext2, ext3 and ReiserFS file systems based Linux volumes. Phoenix Linux Recovery is compatible with all Linux distributions that support the above file systems. The software gets installed on Windows (Windows Vista, XP, 2003 & 2000) and the affected Linux hard drive should be connected as slave.
