Five Common Reasons for Data Loss
Dec 18th, 2015 by aperio

When the drive is damaged physically.

One of the most common reasons for data loss is physical damage. A simple manufacturing defect, or external influences such as shock, dust or power surges may cause internal damage. Anti-static discharge or ESD is also another common cause of failure. Physical damage will inevitably require the help of a data recovery expert. Unless you have a clean room and donor parts, any attempts to recover the data yourself will almost certainly render the data unrecoverable. A data recovery expert will assess the damage to your media before they can determine what parts of it may need to be replaced in order to have the drive working again. Often the expert will use a duplicate hard disk drive of the same make and model to replace damaged parts. Reputable experts will provide a file listing of files and quote for the recovery beforehand.

When the operating system fails.

Luckily if your operating system fails, it means that nothing is wrong with the hard drive itself. The data areas are usually safe, therefore your chances of a full recovery are high. All the expert needs to do is to copy the data from your hard drive to a new one. This can be easier said than done, so take advice. If you are not familiar with hard drives and data structures, don’t risk your valuable information.

When it dies of old age.

As hard drives grow old they experience unpredictable failures. All hard drives will fail at some point, but you will never know when. The mechanical parts of a hard drive will wear down over time and the media surface degrade. Eventually this will cause the drive to crash. Hard drives are becoming increasingly more reliable, but always read the manufacturers ‘mean time before failure’ or MTBF. This is normally calculated in hours and when this has expired, it might be time to upgrade.

If it catches a virus.

Computer viruses can be extremely malicious and damaging to your computer, whilst ransom-ware can be expensive if you fall victim. It is not only recommended but necessary to have a decent anti-virus program installed on your computer. Many users forget that malware doesn’t always present itself as a virus. So anti-malware software such as Malware bytes should also be considered essential. Some viruses will quickly spread around your computer and onto any networks your computer is connected to. So even if you have a mapped backup, catch any malware quickly before it spreads. Make sure you are extremely careful when downloading files and applications online, ensuring they are from safe sources, and don’t open any files emailed to you from an unknown source.

When you accidentally delete or overwrite data.

Manually overwriting data or accidentally deleting it is a common story. Many people will often think their data is already saved somewhere else and will delete the files. While data being overwritten is usually an accident, it is often intentionally done. In criminal and forensic circumstances data may be intentionally erased in an attempt to cover up the tracks of illegal activities, meaning forensic experts may be hired to perform data recovery for the hidden data. Unfortunately, it can be difficult and sometimes impossible to recover data that has been overwritten.

The best way to avoid data loss, is by simply backing up your valuable files on external hard drives or making use of cloud services. If you choose to back up your data, make sure to store it in a safe and secure location away from your computer. This will ensure any damage such as flood, fire or theft will not affect your backed up files. Also make sure that you are saving whole copies of the original files and remember to back up regularly.

Ways to Protect Against Data Loss
Nov 2nd, 2015 by aperio

The statistics are worrying. According to a study done by the University of Texas, slightly over 40% of businesses that experience a catastrophic data loss never reopen and just over 50% of them shut down within as little as two years.

 

Perhaps surprisingly, most data losses are not caused by hurricanes, floods, and fires. A study from Pepperdine University breaks down causes of data loss from most to least common:

 

  • Hardware failures
  • Human errors
  • Software corruption
  • Theft
  • Computer viruses

 

What can you do to protect your business from these risks?

 

Hardware failures

 

To avoid data loss from hardware failures, you must consistently back up your systems and data. You must also consider the hardware you’ll use for your backups. For example, tape backups are known to have a high rate of failure. You’ll want to avoid using them as your backup storage medium. Additionally, you’ll want to have your backup data storage be completely separate from your primary storage.

 

Human errors

 

You can’t completely avoid human errors. Even if your business has well thought out policies data policies along with clear instructions for shutting down and/or rebooting systems, your employees cannot be guaranteed to follow the policies perfectly at all times.

 

The best way to protect your business from these errors and from accidental deletion of files or records is to assume that the errors are going to happen, and back up your data accordingly. Key concepts for these backups are automation and retention. You need to have your backups occur automatically without human intervention. And you need to have retention of data. This means that even if errors are not identified for long periods of time, your data will be available for recovery when the errors are eventually discovered.

 

Software corruption

 

Software corruption occurs when software becomes unreadable by your computer. The causes for this can vary, and the results can be subtle and may go undetected for some time. As with human errors, the best way to protect your business from this cause of data loss is to have automated data backups and retention of data in case the errors are not found for a significant time period.

 

Theft

 

Theft involves copying data for use by competitors or actually destroying it. Copying data this way can be considered a form of corporate espionage. Our blog post, “Cyber Corporate Espionage,” discusses some of the ways you can protect your business from such attacks.

 

Actual destruction of data, however, is a different matter. This sort of vandalism is usually committed by a disgruntled or former employee. You can gain some protection against it by having careful policies regarding employee terminations. These should be the same for voluntary or involuntary terminations, and should include promptly disallowing former employees access to your systems. If destruction of data occurs despite your best efforts, automation of data backups and retention of data are once again your most effective ways to recover your data.

 

Computer viruses

 

A computer virus is code or a program that is loaded onto a computer without the user’s knowledge and runs against the user’s wishes. Viruses can take over computer memory, destroy data, and can often transmit themselves across systems.

 

To protect your business against viruses, you must have a firewall and you must install anti-virus software.

 

Although the risks from data loss are significant, you can take steps to minimize them. Planning for hardware failure, implementing policies to reduce the effect of human error, software corruption, and theft, and protecting your systems from computer viruses are all ways you can protect your business.
