Types of Data Loss And Its Solutions
Losing data stems from an error in information systems. The information can be destroyed by neglect or failure in storage, processing and or transmission. Information systems use backup and recovery equipment in conjunction with a few processes to both prevent loss of data and to recover it once it has been lost.
Types of Data Loss
Data recovery companies that offer Toronto data recovery service exist for a reason that is very simple. People store
information on electronic storage devices and then come to find that there is
not any way for them to retrieve the data that they stored. There are many
reasons for that. Some of those reasons can be obvious ones, while others
happen for inexplicable reasons that require a professional in data recovery
services to find out. People might understand that data loss happens, but what
they might not realize is that it can happen at any time and for a number of
different reasons.
Physical Damage
One obvious way that files are lost – even those containing photos –
is when there is physical damage sustained by the storage media. Take CD – ROMs
for example. This type of storage media is quite sensitive and even if you
simply touch them, you can leave dust particles and fingerprints behind. The
same type of thing can happen to hard disk drives. These act as storage devices
for servers, computers, and laptops. Typically, examples of physical damage
could involve things like fires and floods, which can cause physical damage to
occur with the platters of the hard drive and if this occurs, you will need the
assistance of a data recovery specialist to get any valuable data that may have
been on the drive that was damaged. In fact, you might need to obtain these services before the hard drive is usable at all again. An expert in data recovery software will have the skills necessary to assess the hard drive and to make the decision as to which parts are irreparably damaged and how to get the device in working order once more. They might even need to dismantle a hard drive of the same model for parts.
Logical Damage
This type of damage is far more prevalent than physical damage. Logical
damage primarily is caused by an outage of power that prevents the file system
structures from being totally written right to the storage medium. However,
problems with hardware like RAID controllers, drivers, and even system crashes
can all have the same effect. This is unpredictable, yet some say it is also
inevitable because at some point or another, a hard drive will fail.
Viruses
Today’s world consists of computer viruses that are incredibly advanced and
can cause extreme damage to your computer. It is critical that you have an
anti-virus program on your computer that performs well. Sometimes viruses can
spread quickly throughout your computer and move on to any of the networks that
you might be connected to; making files that they come into contact with
irretrievable. You need to usecaution when you download files and applications from the internet and make
sure that you never open anything that is emailed to you from a source that
isn’t known and trusted.
Accidental Deletion
– Overwritten Data
This is one of the most often seen ways that data is lost. In cases such as
this, the data will be accidentally overwritten or deleted by the user. This
often happens when someone thinks that the data has already been saved in one
location or if they save it in a different location by accident. While it is
often an accident when data gets overwritten, it is also often intentionally
done. Data can be erased intentionally to cover up tracks of activities that
might be illegal. If this is the case, there are specialists known as forensic
specialists who can perform special types of data recovery for data that may
have been encrypted or hidden. The most important thing that you can do to prevent data loss is to back up your files on a regular basis. Do this to a cloud based service or to an external hard drive. If you do this using an external hard drive, make sure that the drive is stored in a location that is both secure and off premises.
