Development of an algorithm for data backup to cloud storage

In this paper, modern approaches to data backup were considered. Various factors that influence the choice of backup method were analyzed, such as the location of the backup server, legal requirements, the frequency and volume of backups, as well as the network speed for data transmission. A comparative analysis of two backup methods was carried out, on the basis of which the D2D2C method was chosen in which the backup copy is stored in cloud storage. This method allows you to effectively protect IP data and provides fast data recovery in case of loss. In addition, the implementation of a backup algorithm to the cloud storage of related data was presented, which allows you to back up when the system is running without interrupting work. This approach provides higher fault tolerance and guarantees the safety of data in the event of a system failure.
