Chapter 7. Disaster Recovery on a Proxmox VE Cluster
In the previous chapters, we covered different concepts of virtualization methods and the components needed for a cluster environment. We learned how to build shared storages with DRBD, GlusterFS, CEPH, and others, and how to implement them under Proxmox to build an HA environment. We also learned how to move our existing operating systems to Proxmox.

Therefore, we will go through the backup and restore processes of Proxmox in this chapter, including the following topics:
- Backup and restore processes of OpenVZ containers and KVM

- Backup and restore processes for a Proxmox cluster
- Recovering from a failed Proxmox cluster
Let's find out how we can make our own backup for the VMs. Note that...
