Disaster Recovery Solution for On-Premises Infrastructure using Proxmox Backup Server

- This article criteria and parameters of disaster area network were described in this research, which allows to evaluate the effectiveness of Disaster Recovery Solution. A modification is proposed to determine MTTR (Mean Time to Repair) for cases of restoring a system element from a backup or through an infrastructure as a code. Conducted a scheme for organizing the restoration of infrastructure by creating a cold site for on-premises infrastructure using public cloud providers. The proposed solution uses the capabilities of Proxmox Backup Server to create regular backups of critical data center components.
