Browsing the web I became engrossed with the concept of data backup and data loss. There is almost an almost unlimited amount of information covering subjects such as how to keep computer and server data secure, how to back-up data, how to restore data, how to replicate data, who will remove your backup tapes to an remote location, which companies can restore data from corrupt disks. With all this information and data technology available I keep asking myself the same question over and over again, how and why is data terminally lost?

Much information on one web site does tend to contradict information on another site, but after all, most companies with sites of this nature are trying to sell you their solution so you will never get an overall unbiased picture, but there is one underlying fact which we can not get away from, a fact that is stated on most sites and the following fact that I totally agree with is, “Data is the lifeline of all companies and organisations; if data is terminally lost then the chances of a company trading efficiently or even surviving after 2 years of the disaster not at all good”. There are various statistics relating to this fact, but it is accepted that 50% to 70% of companies will go out of business within 1 year if data is lost. It is also acknowledged that everything within a business can be replaced, desks, chairs, buildings, even people can be replaced, everything but the data. Imagine, you sit on a chair and it breaks, you buy another one, you get the picture but imagine the consequences of data loss, you don’t know who your customers are, you don’t know who owes you money, you don’t know who you owe money to, you don’t know what orders you have to ship or who you are supposed to be visiting. Dire times are ahead.

Taking all of the above into account I go back to the original question, if people, companies or organisations understand the true value and importance of their data, how do they manage to lose it? Data loss is totally unnecessary and unacceptable! I honestly feel most IT administrators do have the best intentions when it comes the preservation of data. In my experience data loss stems from only a few sources, human error, lack of resource or lack of planning. Total data loss should never occur when hardware fails.

Human error – I forgot to take the tapes offsite when fire or flood struck offsite tape removal company incorrectly labelled your tapes, I did not test the tape prior to backup and consequently my data was not backed up, I forgot to backup! I did not put my tapes in a secure safe and they were stolen overnight. My backup server crashed in the middle of a backup. The web is littered with stories like this; they are almost a comedy of errors. Responsibility for data backup cannot ever be placed upon the shoulders of one person or one team of people, if there is room for human error, then you have a flaw within you backup system.

Lack of resources – If you work for a corporate, your backup and restore system will have probably cost many hundreds of thousands of pounds. You will enjoy an automated disk to disk system replicated to a second remote location. Even though you are replicating to an offsite location, for added security, you will most likely use this second site to backup to tape. This replicated infrastructure is way out of budget for small to medium enterprises backup to tape is still not a cheap task, by the time you have purchased a tape drive, server to fit the drive into, tape media and the backup software you will have spent at least £3,000, plus backing up to tape in the conventional way is still prone to the same potential human errors. The humans that make the error also have to be paid, if a backup solution is not automated then you will have to employ someone to take care of this, I would prefer my staff to be carrying out more proactive, revenue generating tasks.

Lack of planning – probably a harsh way of putting it, a lack of understanding potential disasters may sound more forgiving. It all amounts to the same thing, but a lack of planning was recently highlighted in the UK when the Bunsfield oil terminal exploded. Companies who backed up to tape and secured said tapes in a fire and water proof safe were cruelly exposed when their building collapsed as a result of the explosion, backup tapes could not be recovered for weeks as they were in the safe under hundreds of tonnes of rubble. Their ability to trade was rendered impossible. Most companies feel that this situation will never happen to them, but let’s put this situation into context, Bunsfield is only the fifth largest and one of over 40 oil terminals and depots in the UK all of which are near major towns and cities, so it could happen to you. This case is one of many where buildings have been destroyed and data has been lost as a result.

If you are still with me you will notice I have only mentioned reasons for and ways of losing data. The rapid growth of cheap high speed internet connectivity and consequently the greatly reduced cost of highly secure, fully automated offsite backup solutions is the reason I ask “how can companies and organisations lose data?”

Offsite backup, also known as remote backup, online backup, is a solution that ticks all the boxes for a small to medium companies with limited budget and resource. Why is this the case I hear you ask? If you deal with a reputable company, remote online backup is cost effective, solutions start at around £25 per month, totally automated therefore requires no human intervention resulting in no human error and your data will always be available as it will be replicated between two data centres. To summarise you have an enterprise class backup solution at your disposal for less than the cost of a low end tape drive.

It’s a sickening feeling, the moment you realise that some important document, or irreplaceable photos have vanished from your computer. But that is no reason to despair. The chances are that the data is still present, even if you know you deleted it. Your computer operating system just does not know how to find it any more.

The four most common reasons for data loss are:

* Deletion. You deleted the file by accident during a disk cleanup, or because you thought it was no longer required. It is not in the Recycle Bin. However, the data will still exist until the space it occupied on the disk is are-used by another file.
* Overwriting. You saved a new file over the top of the old one. However, the old data may still exist, and be recoverable.
* File system corruption. The disk suddenly appears empty, or the file and folder names contain gibberish. The files probably still exist, but the pointers to them have been lost or corrupted and the operating system cannot find them.
* Physical damage or hardware failure. You receive error messages when you try to read the disk, or it is not recognised by the computer at all. The data is still likely to be present on the disk itself, but the drive is incapable of accessing it.

In each case, there is a good chance that the data still exists. The computer operating system isn’t able to see it, but data recovery software may be able to. If the problem is a hardware failure then a data recovery service may be able to get back the data using special equipment.

Prepare for data recovery

There is one cardinal rule of data recovery: for the best chance of recovering the files you must not write any new data to the disk they were stored on. The old data will only remain on the disk until the space it occupied is used by another file. If the disk is your computer’s main drive, then the drive is being written to all the time. You should turn off the computer immediately, and use another computer to search for a solution to recover your data. You should put your computer’s hard disk in another computer to do the data recovery, or use data recovery that runs from a CD or floppy disk, because installing the data recovery software on the drive could overwrite the very data you want to recover.

Choosing the data recovery method

Data recovery tools use different methods to try to recover data. Some tools are designed for recovering deleted files, others are better at restoring overwritten files, or recovering files from disks that are physically damaged. Some data recovery software products have been developed specifically for recovering photo images, or Microsoft Word or Excel document files. Such products may succeed where others fail because they understand what these files look like, and can recognise their data when other clues to its existence have vanished.

It can be difficult to choose the most appropriate data recovery method. Tech-Pro has created a website called Get Data Back. It has a Data Recovery Wizard that asks questions about the data you have lost and how it was lost, and then recommends the product that is most likely to be successful. It will also advise you if it would be better to use a professional data recovery service. Give the Get Data Back data recovery site (http://www.get-data-back.com) a try if you need to recover lost files.

It happens all too often. You’re downloading your latest snaps from your digital camera, and the computer freezes. After you restart and try again, there appear to be no pictures in the camera. Or perhaps the photos were on your hard drive and you deleted them accidentally, or you didn’t have a backup and your hard drive failed.

Whatever the cause, there is no reason to panic. The computer may no longer be able to find your pictures, but it’s unusual for a fault to completely wipe them from the storage card or disk. With the aid of some inexpensive data recovery software, you’re almost certain to be able to get your photos back.

There are many data recovery programs on the market, but for photo recovery I strongly advise using software specifically designed to recover digital images. This kind of software has several benefits, not least the ability to show a preview of every recovered image. Often, data recovery tools find files that look like they might have been a digital image, but aren’t. The preview feature saves you wasting time recovering files that turn out to be junk.

Another advantage of specialised photo recovery software is that it looks only for photo image file types. It knows what JPEG and other image files look like on disk. This improves the chances of a successful recovery, and reduces the number of junk files that are found.

Modern data recovery software is easy enough to use that anyone can do it. You just start the software and tell the program where the drive containing the missing images is. The software scans the drive looking for the patterns that it recognizes as photo image files. When it has finished, it will display a list of files, with thumbnail images showing the content. All you have to do is select the photos you want to recover, and safe them to a safe place on your hard disk.

Even though the hard drive stores data, it isn’t perfect by any means. Hard drive failure is very common with all computers, with no real way to prevent it. Although there are several different reasons why a hard drive can fail, the most common is overheating. Viruses and crashes are common as well, along with theft and accidental deletion.

With the older style and mechanics of hard drives, the RPM speed was low, meaning that the drives wouldn’t overheat. The hard drives we use now days, have speeds between 7,200 and 10,000 RPM, meaning that they can get quite hot when they start working. Computers of this day and age come with fans to cool everything down, with most hard drives including temperature sensors as well, so you can keep track of just how hot your hard drive becomes.

With hard drives today, overheating is a very common problem. The faster hard drives come with speeds of 10,000 RPM, which can make the temperature soar above 70 degrees F, really heating things up inside the drive. The mechanics on the inside are built to withstand the heat, although if things become too hot, you’ll encounter problems. If a drive becomes too hot and ends up losing the data, it may be next to impossible to retrieve the information – no matter how good your data recovery specialists may be.

One area that suffers from the drive overheating is the platters, which are magnetic media. Platters are what carry the data throughout the hard drive. Platters are constructed from optical glass, aluminum, or ceramic and normally coated with a layer of magnetic material. Once the hard drive begins to heat up, the platters will start to expand, which changes their size. When this happens, the magnetic surface on the platters will get destroyed, which results in a loss of data. If the physical area of the platters are damaged, it will result in unreadable sectors.

Other areas of the hard drive that can be damaged due to overheating are the read and write heads, head actuator, and the controller chip. Hard drives are very sophisticated pieces of hardware, and can’t handle overheating. The read and write heads are a common example, as they can easily render the drive useless if they become damaged.

To prevent your hard drive from overheating, you should always make sure that it is cooled properly and well ventilated. You can always get additional fans and coolers, which will improve both ventilation and the flow of air in your computer. You can buy fans and coolers at very affordable prices, which makes them an ideal investment for keeping your hard drive or hard drives cool.

You can also get software that monitors the temperature of your hard drive as well. Whether it’s software, or additional fans, you should always ensure that your hard drives are kept cool. By keeping them cool, you’ll greatly reduce the amount of crashes. You’ll also increase the stability of your hard drive as well, which will make your entire computer perform much better.

Have you heard of data/file recovery? The definition of the term Data Recovery is “..Making previously lost or damaged data available again..” A data recovery software or method can help us recover destroyed data e.g. an accidentally deleted file. It happens all the time. You delete an important file on your PC and send it to your recycle bin by mistake. You realize what you’ve done only after you’ve cleaned the contents of the recycle bin.

What do you do now?
That file you deleted was so important. Fortunately there are lots of methods (Data Recovery Methods) and software (Data Recovery Software) available to help you get your lost files back.

Let’s start by mentioning some possible reasons for the loss of data:

* You accidentally delete an important file. Then you immediately shred the contents of your recycle bin
* During today’s system crash some files just disappeared and cannot be located or accessed
* You format your hard drive but then you remember those important .zip files previously stored in the newly formatted empty medium.
* A power outage prevented some files from being written to the hard disk.
* Data loss can also occur due to physical damage of the storage media. For example the surface of your CD-ROM may be scratched off or your hard disk may suffer from all kinds of possible mechanical failures.

..and the list goes on.

Is Data Recovery Important?
Data recovery is a very misunderstood concept. A lot of people may not even be aware of the existence and the importance of data recovery. Maybe they think of it on a personal level. The truth is, lost data causes financial disasters to companies all over the world. The cost associated with computer downtime and lost data is enormous (several million dollars) for businesses.

How to deal with data loss?
Losing files is easy but recovering them can be difficult. If the loss was due to physical damage then you need someone with experience, a hardware technician or something. It wouldn’t be wise to try to overcome hardware failures alone unless you are a professional.

Now, if the loss of data was due to logical failure or human error then the solution is data recovery software. The data recovery software should be able to:

- Undelete files even after you’ve shred the contents of your recycle bin
- Recover files after you’ve been infected from a malicious threat (trojan, worm or other virus)
- Recover files from reformatted hard disks or after your system crashes or your hard disk fails
- Recover all types of files (all kinds of documents, images, music, videos, email messages, zipped files etc)
- Recover data from all types of storage mediums (hard disks, external drives, CD-ROM, usb drives, floppy disks etc)
- Recover files easily and successfully. Should be user-friendly allowing someone with no data recovery skills to use it
- Take/create backups of critical system files or files you choose

The best way to avoid data loss is to start taking backups of your important storage mediums. Either create backups of data on CD-ROMS or use an external drive or zip drive to back up your critical files. If you want to go further look for software that automates the process of backing up and storing your data. These programs are kind of “set and forget”. You set it up to take backups every hour or every day or month etc. and let the software do the rest.

Computer files are a lot more important to some people than their lives because it represents their whole life’s work and achievement. There are people who rely on their computers for almost everything, from their daily schedules, business and personal files and what have you. The possibility of losing their computer data is thus a horrifying thought for them.

Even a student who uses his computer to store assignments, research papers and other school data will be dismayed at the though of losing such files. What more for a computer dependent entrepreneur who relies on his computer for the day to day existence of his business. Losing computer data for both types of computer users would mean a catastrophe because once lost, computer data can no longer be recovered.

However, technological advancements have made data recovery possible depending on a lot of factors. For one, computer users are advised to make back ups of their computer data to make sure they would not be caught red handed when computer data is destroyed. For some who hold very important computer data, the back up itself should even be further backed up to make sure there is a way of recover lost data.

Fortunately, there are companies who offer data recovery services in case of an unforeseen disaster like corruption of files or crashing of a computer hard drive. People who store very important data in their computers need to have back ups but in any case, they should be acquainted with a computer company that can offer them fast and efficient services for the recovery of their lost computer data.

It is thus pertinent that computer users have a way of knowing where to contact computer companies who can recover lost data for them no matter how such data was lost. There are various ways of losing precious data and one of those is carelessness. People take for granted that computers are very fast and efficient machines they can accidentally command their computers to lose or delete data in a flash.

The widespread use of internet has also been responsible for thousands of computer crashes all over the world because of viruses that attack computer hard drives. There are plenty of technical reasons why data is lost. Added to that are unforeseen disasters like fire or other calamity.

Computer users who have backed up their lost data but who discover that their back ups do not work still have a recourse. Rest assured that there are companies and software that can recover your computer files efficiently and quickly to minimize your potential losses.

Companies providing data recovery are equipped with technical people who around the globe and are more than capable of bringing back lost data. You just have to be able to know them beforehand so that when your computer data gets lost or destroyed then you have immediate access to their services.

Computer Diagnostics is a need to keep a healthy operating system and vital for business productivity, where a failure can be a costly mistake. PC diagnostic software can determine hardware and software conditions and possible failures, as well as current settings and connectivity.

A PC diagnostic program can also suggest the best performance settings in order to get the most of your system according to your hardware specifications. In addition, a PC diagnostic tool can help you to identify potential problems that can damage your hard drive or any other piece of hardware.

Some companies provide troubleshooting tools to test your PC’s electronic circuits, in the form of system plug-ins or stand-alone applications. Computer Diagnostics should also be able to check other computer components such as the BIOS, serial and parallel ports, USB and Ethernet ports, etc.

Choosing the best PC diagnostic software depends on your computer related knowledge. You may find a PC diagnostic program worthless if you do not understand what a benchmark diagnosis means, or cannot make changes in the settings that the PC diagnostic tool may suggest.

Computer Diagnostics provide end user with intuitive diagnostics tools for troubleshooting while improving performance. However, some of them can be risky if you do not understand what they can do, like those including the ability to reformat any type of hard drive.

Most software developers state, “use it at your own risk” because of the lack of knowledge that can lead also to massive data loss. Although data can be recovered, it is a painful process because of the required proper software or you may have to take the hard drive to a service center that can restore and reformat your hard drive.

Even then, there are no guarantees of getting 100% of your data back, so be careful choosing software intended for Computer Diagnostics, and always read before clicking any “OK” message that may pop up.

If a PC diagnostic tool returns the parameters of the hard drive, and allows toggling the IRQ directly to determine which I/O port is at which IRQ, make sure you understand what all this means before proceeding, because the software can read, write, overwrite and edit most values.

Perhaps the best PC diagnostic software is that which can only read, generating log files or an overall detailed report of your computer including all its components.

If the PC diagnostic program cannot write, the possibilities to damage your hardware or destroy your content are very low, although other problems such as a buggy, unstable version can ruin your operating system.
