Cloud Backup


One of cloud technology elements that enjoy a wide implementation in the real life is remote backup, also known as cloud backup or online backup. As of today, tens of cloud backup services offer cloud storage for backups under various conditions and fees. Cloud backup market is extending with rapidity of geometric progression.

Cloud Backup


Cloud offers a set of advantages compared to usual (local) backup creation.

Advantages of cloud backup
Firstly, stored backup can be accessed from any location in the world. To a certain extent cloud backup is another way of data transfer both between computers of the same user, and between different workstations.


Secondly, user no longer has to care about integrity of a compact disk containing important backups or viability of a volume on hard disk drive dedicated to backups. Since data is uploaded to the cloud, its physical preservation becomes responsibility of the data center’s owner, whose service is used by cloud storage provider. The portion of liability is usually denoted in user agreement.


Thirdly, cloud backup is traditionally offered as not just a free space on remote disk, but as a tool of backup automation. Customer receives client software for one of popular platforms, as well as access to administrative interface to his personal section at the server, which allows adjusting settings of backup to meet even the most exotic needs.


However, regardless of obvious advantages, many potential customers are rejecting the service due to trivial distrust to cloud technologies, particularly connected to the danger of third parties getting access to the information. As a result, a portion of customers refuse to upload their data to the cloud, and another portion can accept it only for backup of non-critical data (and immediately a question arises, where to put critical data then?).


Up to recently, low bandwidth channels were also listed as a disadvantage of cloud backup. But the largest amount of information is uploaded to the server only the first time it is accessed, and only changes are uploaded afterwards. Results of a day-long work of most users can be easily transferred to the service even if the channel is not really fast. This disadvantage gradually vanishes as the Internet is developing though.
