Knowledgebase on A description of the main threats to data securityIf you have faced data loss at least once in your life time, it is the best period to choose know a description of the main threats to data security. But first let us see what is the data loss. The data recovery is a huge business. The normal computer user does not have any idea about data loss recovery. If you are one of them, please scan this article.
Data loss is one of our industry's Most misunderstood concepts. Modest information has been made open about data loss, and the information which is available is confusing. Due to the varied messages they receive, users find it complicated to properly assess their data loss situations and make right decisions to recover from them.
A large amount "lost" data is not vanished at all; it has simply become hard to get to the user. Hundreds of thousands of gigabytes (GB) of data have been lost simply because users were not aware of their alternatives and gave up chance of recovery.
While data may be unreachable to you, our experiences indicate that about 95% of all inaccessible data can be recovered. This number approaches 100% if the drive is received before commercial utilities are exercised. The professional data recovery experts have the skills to recover your data using favorite techniques and tools.
Do you know how the data is stored in a hard disk drive? Hard disk drives store data on one or Other metal oxide platters. These platters, which rotate at a rate of 3600-10,000 revolutions per minute, hold magnetic charges. A read/write head attached to an actuator arm literally floats on a cushion of air, 1-2 micro-inches (one millionth of an inch) above the surface of the platters. Data flows to and from these heads via electrical connections. The disturbance in force setting can cause data loss.
Extra data is being stored in smaller spaces. Some years ago hard drives stored 40 Megabytes (MB) of data. Today's hard drives store up to 240 gigabytes (GB) on a smaller surface than the drives of a decade ago. Increasing storage capacities means chances of more data loss. As additional data is stored in lesser and denser areas, mechanical precision becomes vital.
As a part of this latest technology, the drive tolerance (distance between the read/write head and the platter where data is stored) is gradually reducing. A slight push, a power surge or a contaminant introduced into the drive may cause the head to touch the platter, resulting in a head crash. Even a microscopic dust particle can cause complete data loss. In some situations, the data residing in the area touched by the head may be permanently destroyed.
The current tolerance drives is 1-2 micro-inches (millionths of an inch). Comparatively, a speck of dust is 4-8 micro-inches and human hair 10 micro-inches. Contaminants of this size can cause important data damage.
Backup technology and practices have failed to adequately protect data. Virtually all computer users rely on backups and redundant storage technologies as their safety net in the event of data loss. For many users, these backups and storage strategies work as planned. Others, however, are not so lucky. Many of our users back up their data, only to find their backups useless in that important moment when they need to restore from them. These systems are designed for and rely upon a combination of technology and human intervention for success. For example, backup systems consider that the hardware is in working order. They assume that the user has the time and the technical expertise necessary to perform the backup properly. They also assume that the backup tape or cartridge is in working order, and that the backup software is not corrupted. In reality, hardware can fail. Tapes and cartridges do not always work properly. Backup software can become corrupted. Users accidentally back up corrupted or incorrect information. Backups are not infallible and should not be relied upon absolutely.
Dont let this happen to your important data. You have check the all aspects of the data backup system regularly. Whether hardware is working properly? Whether software is getting the backup at regular intervals? As the interval between two backups increases, your chance of losing data increases. But if you reduce the interval, your work time reduces. You have to balance this activity.
