Well, as a cure have a fresh copy of the file system and prevent the further issues. File system bugs always prove as a threat to the users most important assets- data and create a Linux recovery need for them. The main reason is the fact that file system retains the pointers which tell where the data is located on the drive so that it can be accessed. Now, as we reinstall the file system, those entries also get wiped off. Thus the new file system copy is nothing more than the dumb file structure for the existing data. Now, to recover all those which have got rendered in the hives of hard drive, proper data recovery Linux mechanism is required. Suitable scanning mechanism and safe interaction with the file system will yield you what you want. Data recovery Linux software has been designed, considering this fact only.

Dirty shutdowns, minor file system inconsistencies and more, these are the common problems with Linux operating system. So at each boot, the criterion of fsck is meant for preventing the data loss problems with Linux. But contrarily, serious data loss issues have been seen, when the user loses power when fsck is on its way of routine checkup.In some of the reports, when the user restarts the system, the partitions have been found to be inaccessible. This is the critical situation of data loss as whole of the data appear to come to an end. For the further investigation of the problem, when the user runs fdisk on the partition, similar warning may be seen:Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)Command (m for help): pDisk /dev/hdb: 203.9 GB, 203928109056 bytes255 heads, 63 sectors/track, 24792 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesDevice Boot Start End Blocks Id SystemCommand (m for help):This warning hints you of the creepy act with the partition table of hard drive; as a result all the partitions have become inaccessible. Partition table is the 16-byte information, describing all the information about the hard disk partitions.

For a business to thrive on the internet it's vital to choose the correct hosting solution which suits your business and meets your business needs. As no two businesses are the same its important to know the difference in the web hosting options available. Whether you are a start up business, running a small business or a large enterprise business, you will need to compare several different options before making any decision on a web hosting package.Dedicated Server or Shared Hosting?

Firstly you need to find out if you will need dedicated hosting or if shared hosting is good enough to meet your requirements. Usually large businesses will have a very large website, with lots of databases and have a heavy amount of traffic, if this is the case your business will probably will need to have a dedicated server hosting package. A dedicated solution will give you all the resources of an entire server at your disposal solely for your website. Having a dedicated server will also increase your security, which is an important factor especially if you are storing customers private information on your website. The main downside to having a dedicated server is the price, a dedicated solution can be quite expensive but if your business relies on on having good reliability, experiences large volume of visitors, requires enhanced security and is growing at a fast rate, then a dedicated server is definitely worth the money. It will inevitably become a valuable asset to your business and be necessary for your business to function online at an optimum level.

However, if your business website is not to large, doesn't need extra security and not expected to experience a high volume of visitors then a shared business web hosting solution will be more than adequate. Shared hosting basically means that your your website and hosting plan will share the servers web space, bandwidth, the RAM and all the other resources on the server with other websites and hosting plans. Shared hosting is easily the most popular type of web hosting available and offers many benefits, especially if money is a concern, many shared web hosting plans now offer unlimited web space and bandwidth which are excellent value for money.

Consider a Cloud Hosting solution?

For many companies, a hosting solution that may suit your business well is Cloud Hosting. Cloud Hosting offers almost all the benefits provided with a dedicated server hosting solution, the only difference being that cloud hosting is considerably cheaper. This is the reason why cloud hosting is becoming very popular. Cloud hosting gives you a solution somewhere in between having a shared hosting and dedicated hosting solution combined. It gives also gives you the power of cloud computing, which can be of huge benefit in many different ways. Some cloud hosting packages also give you the resources of several servers simultaneously, offering an impressive powerful solution and an extremely efficient uptime.

Choose you Platform, Linux or Windows?

Another crucial aspect to get right when choosing a hosting solution is the platform. Find out if you have a Windows or Linux based website. Linux based hosting is easily the most popular hosting platform on the Internet. The reason for this is because most website technologies that run on the Linux platform, including the operating system itself, are all open source. Linux hosting is also cheaper because of these factors and having the ability to use PHP, Perl, MySQL, as well as others make it very scalable.

However the Linux platform is not fully compatible with most of Microsoft technologies. The Windows hosting platform is all based on the Windows operating system. The platform supports all microsoft programming frameworks, including ASP, ASP.net, MS SQL, ColdFusion and VB. Windows based hosting or servers are the perfect solution for those who need easy compatibility with Microsoft based technologies.

Linux hosting is very similar to normal web site hosting, only that the platform used here is Linux operating system (quite obvious). Linux provides a very secure and highly function able platform for all kinds of work. The Linux operating system allows for an open source environment and the technologies used are highly familiar such as PHP, XML, SQL and others. The webmaster is spoilt for choices commonly regarding the functions. famous distributions of Linux closely resemble Windows web hosting. A closer look at the various types of Linux web hosting would help:

Ubuntu: This is the most general among the several forms of Linux web hosting. This type of hosting allows for all the fundamental features needed for website hosting such as web browser, instant messaging, office suite etc. Ubuntu also serves the best accessibility features of the software community.

Kubuntu: Kubuntu is truly identical to the Ubuntu form, with it providing an open source environment as well. Used all over the world by programmers and developers, this form of web hosting provides a nice active platform to build on high end versions of a website.

Debian: Successor to Ubuntu and Kubuntu, this form came with a few new features in addition to its predecessors. However the fundamental structure of Debian remains the identical as of Ubuntu and Kubuntu.

The adjustability of Debian remains its aegis, with complexity in operation being a bit of a defect. Debian is a true GNU/Linux distribution using the standard UNIX style commands to assure the knowledge that one had learned on Linux is sustainable for the next few years.

Debian is a greatly stable and robust platform for website hosting, with outdated hardwares such as Pentium working pretty well. Quite obviously, this is one of the most popular web hosting services offered by Linux.

Fedora: Fedora is a Linux based operating system which allows access to the most updated free and open source software. Today it is the second most famous Linux- based operating system. Security is one of the most significant features in Fedora. One of the key security measure is called Security-enhanced Linux, an important feature which enabled the mandatory access controls in the Linux Kernel. Fedora provides users with the access to the latest open source software in a secure environment and easy to manage form. It is a center for innovation in open source software, and it helps to encourage a community with multiple roles such as developer, artists, system administrators and many more. All of them come together as a powerful force for one good reason: for a better improved eco-system which would advantage the society with celebrated and long lasting effects.

CentOS: CentOS stands for Community Enterprise Operating System, which is widely approved by people as the core of cPanel. The stable accomplishment of CentOS has led to several commercial usages. As the name suggest, CentOs is supported by the community of Red Hat Linux group, and is free and open sourced.

Other forms of less approved Linux web hosting are also accessible.

Linux has several kinds of OS or operating systems, named Linux distributions. There are now more than 600 distros or distributions. A number are described as very light, while others let you operate Linux using another operating system. There are also complete systems that have a wide array of applications.

Tips for First Timers

First timers might want to try out Linux distributions first. You can test by using Knoppix, a Live CD distribution. Linux can boot directly from the CD. You do not even have to install the operating system on your personal computer. Knoppix will also allow you to run and operating different Linux programs, make and save new files within the hard drive. Wubi can also be used to install another famous Linux system called Ubuntu, even if you have a PC based on Windows. Wubi will let you install and run Ubunta, just like a regular application.

First timers can also try Linux Mint. This is supported by many available programs and also is available with mint4win, a tool that allows you to install the operating system without the need to change the configuration of Windows. Ubuntu is ideal for beginners. Other good systems include OpenSUSE or Novell and Fedora or Red Hat. These Linux distribution systems are easy to use for starters. Xandros is categorized as a commercial distribution system, but will allow you to run several applications like Photoshop, Windows applications and Microsoft Office.

Other Uses

Another good Linux distribution system is Puppy Linux Live CD. This can be run on old or slow computers that only have 64MB of RAM. The CD will boot from the CD, a USB drive or a zip drive. AntiX and Xubuntu can also rely on other resources and operate well on older computer models. AntiX can operate on Pentium II specifications. Other good systems include Damn Small Linux and Zenwalk.

At work, you will best operate using Red Hat or Novell Linux. Red Hat is focused more on the server market, compared to the desktop. Xandros is also ideal. Ubuntu can operate on servers and Red Hat is excellent because it keeps your activities and files safe and protected.

Other Available Systems

Netbook users will like a number of Linux distribution systems like Jolicloud, Ubuntu Netbook and Moblin. Using the operating system of your Netbook you can install Ubuntu conveniently. Simply follow the instructions onscreen.

Advanced users generally prefer Arch Linux and Slackware. The Linux distribution system can be installed from nothing. It does not have a GUI and is recommended for experienced users only. Slackware is very fast and one of the first distros available.

Linux has developed much through the years and has made it possible for every user to operate, regardless of their computer experience, computer specifications and existing operating system. The options are vast for any type of user who wants to enjoy the different programs and applications. You can get these systems online or at designated computer and software stores. Search online for more features and details.
