In an ideal scenario, all business data will be backed up in real time (or almost real time). In such a scenario, any data lost will be immediately be recovered in full or almost fully from the back ups, and operations will continue with a minimum of pause. In realistic scenarios, however, staff will probably be overburdened with day-to-day operations to back up all data. Even if data is backed up, it might not be tested for recover-ability. In this scenario, data recovery services become a critical requirement.

Data recovery companies provide a range of services from providing consultancy over the Internet for simple queries to helping recover from a major data loss incident after a serious disaster like a fire or flood. Severely damaged data storage media will typically require highly specialized facilities and expertise to recover from For example, data loss in a RAID environment can involve not only repairing the individual disks in Class 100 Clean Rooms, often replacing failed components with matching healthy ones, but also rebuilding the RAID array painstakingly.

Data Loss can occur Owing to Many Reasons

A major disaster like an earthquake or tornado is not a pre-requisite for a data loss incident. Even in the course of day-to-day operations, a system or application software bug or a power supply disturbance can lead to data loss. The situation can then be aggravated by continued operations that damage even the good data on the storage media. Human errors are other typical causes that lead to data loss, minor and major.

The following symptoms can indicate that a data loss has occurred (or will occur soon):

• The system BIOS fails to detect your hard drive
• The system is not booting up, or doing so in an unreliable fashion
• Files and folders that were on the disk suddenly disappear from directory listings
• The hard drive is making clicking or grinding noises during operation
• The hard drive does not seem to be operating properly

If you notice any of these symptoms, the best course is to shut down the system and contact a competent data recovery professional. That person will then be able to guide you on how to proceed.

Data loss can happen owing to:

• Operating system or application crash leading to corruption of data written to disk
• Power surges or failures that causes incorrect or incomplete data write operations
• Accidentally deleting valuable files, or formatting media containing such files
• Drive failure leading to a read/write head crash or other physical problem
• Virus attacks that damages data in different ways or even formats the entire disk
• Malicious actions by a disgruntled employee or a competitor or a hacker

These are ordinary events that can happen any time (unlike major natural disasters like a fire, flood, earthquake or tornado). What this means is that data loss can occur even in the course of a normal day. And as mentioned above, if you notice any data loss, the best course is to shut down the system and contact a competent professional.

Data Recovery Services

Data recovery services professionals will diagnose the damaged media and assess the kind and extent of damage. Such a diagnosis is an absolute necessity to decide what needs to be done to recover the data.

Where only simple file system damage has occurred, repairing the file system (often using data recovery software tools) can make the data accessible and readable again. This type of data recovery can also be done in-house provided the organization is definite that only file system damage has occurred. In the absence of such a certainty, recovery software can often aggravate the problem and make data recovery more difficult (and expensive) or just impossible.

Physical damage like drive head crash will require opening the disk and replacing faulty components. This can often make the data readable again. Such recovery can never be attempted in-house unless a certified data recovery professional is available, along with specialized data recovery facilities. In addition to damaging the disk by the dust in ordinary environments, manufacturer’s warranty on the disk will also be voided if the disk is so opened.

Data recovery service providers typically provide different types of services in different situations. In normal cases, each data recovery case will be attended in the order they are received, involving several days to complete the service. In more urgent cases, clients can negotiate for expedited services with considerably shorter turnaround times. In extremely urgent cases, the service provider might put an engineer immediately on the task, 24/7 and 365 days (and nights) a year.

Data loss is too frequent and common an occurrence to be ignored even by personal computer users. While simple data loss incidents can often be recovered from using a data recovery software, more serious cases will need the services of a data recovery services professional.
