Expand the Capabilities for Backups a Paas-Type Virtualization System

Currently, resources in data centers are used extremely inefficiently. Storage systems are loaded on average about 25%, and servers and network resources - up to 30%. After implementing virtualization, the resource load level in a well-managed server environment increases by 30% to 90%. Virtualization undoubtedly provides many advantages in an infrastructure. One of the most important is the ability to easily create and manage backups of virtual machines, as well as quick recovery if necessary after disasters or accidents. Recovery time is many times faster than when applications and the operating system are hosted on a real server, while the loss of information with proper management is from zero to minimal. The available weekly and daily backups in Proxmox VE are not always flexible enough to properly organize backups in an IT infrastructure. In most companies and organizations there are virtual and real servers that play a significant role, but the data in them, as well as operating systems change very rarely. With existing methods, weekly backups need to be set up to ensure the reliability of the data and to recover quickly in the event of a disaster or accident. The paper aims to research and propose approaches which can extend the bult-in backup process by adding monthly backups for Proxmox VE. The research discusses the optimization of the process of creating backups to reduce network traffic between nodes and storage, as well as optimizing stored storage data.
