What is a cloud storage?

Cloud Storage is a retention data technology in which the user's information is kept in a remote location rather than on local hard drives. This system provides an alternative to traditional backup systems by allowing data recovery in the event of a catastrophic event at the user's place. Online storage also allows users to access their data wherever they have Internet access. Several companies offer their customers a limited amount of free online space and have set up subscription services that automatically back up the user's hard drive in the planned times. Some technology experts theorize that almost all data will eventually be kept in a cloud storage. Some e -mail services keep copies of correspondence on their servers so that users can access the stored post office from any computer or smartphone. The small size of these files allows keep services to thousands of archived e -mails on a relatively small amount of server.

Cloud computing has increased the cloud storage value, as users in some areas can now create and edit free online documents without ever living on the user's hard disk. This system allows a group of users to edit the document without having to share data or worry about file updates on their personal computers. The proposed thin client computers would work completely in the cloud, with all applications and data existing on a remote server.

The ability to back up data outside the web is one of the most important aspects of this technology. Traditional backup systems require the user to copy important files to external hard drives or disk -based storage. One disadvantage of this system is that any event - such as fire or theft - that damages the user's hard drive can also destroy all backup units storedé in place. Although backup discs are kept in another physical location, they can still be influenced by a large natural disaster such as earthquake or tsunami. The cloud storage avoids this problem by maintaining redundant files in secure data centers in various regions.

Cloud storage has several disadvantages. If the user is in place without an Internet connection, he will not be able to access his data. Another problem is that the user can forget the login information for his account. This can cause delay in access to data, while the user's identity is confirmed by other means. The final problem is the vulnerability of cloud data for hackers and other cyber criminals who can use security holes and gain access to the information stored online.
