Hello, I'm very new in Proxmox and I have very important question to ask, because I'm very carefully planning the backup solution. I would like to ask is it possible to configure Proxmox and it's Backup server according to the situation below:
1) Server A with Proxmox installed makes backup to another Proxmox server B (separate disk array for backups) over the local network.
2) Server A damages and it goes offline.
3) Server C with Proxmox is turn on and I manually mount Server B directory with VM backups (VM disks) and this combination of server C and B starts serving like it will be Server A. I mean, as the example, I need in a very short time attach Proxmox to NAS and use VM backups (images) from there. Can I fulfill such scenario with Proxmox Backup Server?
My purpose is that two Proxmox servers A and B is always on and have some different virtual machines running. Both servers are using 90% of resources and they are doing backup to each other. When the situation comes that one of the servers is damaged and can't be repaired quickly, the server C is started. Server C mounts the backup (VM disks) and and work like a quick disaster recovery solution.
And the second question about such case mentioned above performance. What do you think, will NFS connection between Server B (VM storage) and Server C (VM host) can handle the load of 1000 website and 5000 mailboxes on KVM machine through 1Gbps network? Won't be troubles in such scenario? I need that several week it will serve for the customers very flawlessly while server A be repaired.
