data recovery

To restore the data associated with a variety of ways to extract data from inaccessible or damaged magnetic media. The technology is very different, and there is no set standards for devices for this type of service. Demand for emergency data recovery is steadily growing, and time together, different mechanisms have been established, which may help in the rebuilding process.

Sources of data recovery can be attributed to the opening of Charles Babbage and Ada Lovelace. In 1833, Babbage began work on creating the first computer. The invention, which was later known as the Analytical Engine, was on the components of modern computers we use today is based. Babbage worked on plans for an engine for eleven years until its development during the workshop in Italy, reported in 1841. Italian Menabrea they have written a summary of the workshop and published an article in French. In 1843, Ada Lovelace translated articles Menabrea Babbage and invited to add their own notes. These records were 3 times the length of the original article, and Ada and Babbage's ideas combined to create an engine crawling. Programs for the engine was hit in the charts jacquard, so that the machine is known as "punch-card system." But Babbage and Lovelace eventually faced with the problem: one of these cards have not been damaged broad support Babbage in processing. Recovering data from damaged punch cards proved extremely difficult, indeed, that neither Lovelace, Babbage can be done. The communication system for advanced data storage necessary for the proper restoration of lost data. This was the first known example of the need data recovery technology.

Developed in the period after checking the engine domain (computer), so that the field of data recovery has grown at a rapid pace, an overwhelming majority. Consequently, the requirement to collect new data with the same speed. Many new ideas and concepts that have emerged technologies is well underway. One of the greatest achievements in the field of information technology was ENIAC in 1940.

ENIAC (Electrical Numerical Integrator and Computer) was the first multi-purpose computer. In the next ten computers are used for commercial purposes, primarily because of the incredible feats of ENIAC. Not only in desktop computers to store more data, but with the invention of the ENIAC computer was more frequent. Thus, there was more space for storage and more people use computers to store information. Another important achievement in this industry, IBM was the first vacuum column tape drive for data storage in 1952. This store of new discoveries and expand refineries computer. Before the column was introduced, was weak magnetic tape used to store data. Tape was fragile, reasonable facilities for storage, but the frequency of rupture and sudden starts and stops high. Empty column IBM was recorded tape in a vacuum in the movement. To break leads to a decrease in cases of loss of data and retrieve data more easily if a problem occurs. In 1962 he was introduced probe logic. The logic probe is used in electronic logic circuits, not looking at the chips. Although the logic of the probe changes state, it helps if the real reason, the chip may be provided otherwise.
