Total volumes of data exceed 1800 exabytes in 2011

In a report published by research firm IDC forecast that by 2011 the total volume of information stored all over the world on all existing digital media to exceed 1800 exabytes, which is 10 times more than in 2006, when the total volume of stored data worldwide .

Analysts at IDC say that the annual growth rate of the volume of data stored in the world make up 60 %, which is higher than expected 3 years ago. ' The number of files that exist on computers, servers, notebooks, storage systems and removable media, increases almost exponentially ... ' In fact, if you translate all the volumes of information into simple bits and count them, then that number will already exceed the number of stars in the universe. On the basis of calculations it can be argued that the amount of data every five years, increasing tenfold '.

The compilers of the report give an interesting comparison: if the current trend continues, by 2023 the number of stored bits of information exceeds Avogadro's number, which denotes the number of carbon atoms in 12 grams ( 602 200 000 000 000 000 000 000 atoms).

Also in the forecast of IDC says that the increase in the number of files stored in electronic form, a 50 % higher than the overall growth of stored data, so that by 2011, analysts predict the emergence of 20- kvadrilionnogo file (20 million billion).

Analysts say that by the end of 2007 the world has about 281 exabytes of data, almost 10% more than forecast in 2006. The discrepancy was explained in the company over the soaring popularity of digital media carriers and volume graphics, audio and video files over the WAN.

By its structure exist today are very different files - be it as a 6- GB DVD-ROM images, and metadata files to RFID-tags, size does not exceed 128 bytes. However, studies show that users are actively exploited by at least half of all stored data, the rest of the files - this is the so-called ' digital shadow ', which include the files in the web browser caches, log files on the servers, data is already committed transactions, web history .

In IDC, the world's largest manufacturer of storage systems, the company EMC, said that if business users and IT managers take a look at the information stored on their servers and desktop computers, they will be unpleasantly surprised by the growing volume of. However, this problem - just the tip of the iceberg. The collected data must somehow protect and preserve what is becoming a more laborious task.

And third, does not prevent the use of modern solutions which avoid the uncontrolled growth of files. These solutions include virtualization, centralized storage, data protection and convert them into a structured form using the database, writes. CyberSecurity.

' A simple letter of 1 megabyte sent to four email addresses, generates a total of up to 50 megabytes of information. This is necessary to remember ' - say at IDC.
