The article describes the possibilities of data backup with the help of cloud services in data management in networks. It also describes how to create backups, how to verify the integrity of files in a backup, and how to ensure the reliability of the copies themselves. The formulation of the problem is formulated as follows: it is necessary to find the best way to store backup data ensuring the best safety of these data at the lowest cost and reduce the complexity of the backup. As optimization criterion in this study was considered work on backup software, data storage reliability, the integrity of the files in the backup, the financial costs for providing backup. Analysis of the results of the study showed that the storage of backups in the cloud compared to traditional methods of backup - more profitable in many aspects. In modern data centers due to the large scale of the level of reliability of data storage is much higher, the cost of disk space does not vary significantly with the cost of purchasing hard disk and automatic backup check allows you to save a lot of time.
