Disaster Recovery for VMware, Hyper-V і Proxmox

DR is not only backup. DR asks how company starts after incident: where VMs run, network, DNS, firewall, login, data, service priorities and who decides failover.

Коротка відповідь

DR is not only backup. DR asks how company starts after incident: where VMs run, network, DNS, firewall, login, data, service priorities and who decides failover.

RPO/RTO without magic

Each service needs accepted data loss and downtime. ERP, mail, files and monitoring have different requirements.

VMware, Hyper-V, Proxmox

Each platform has different snapshots, replicas, backup and restore mechanisms. DR must include hypervisor, storage and network.

Network after incident

After VM restore you need addressing, DNS, firewall, VPN, admin access, certificates і user communication procedure.

Runbook і test

DR plan must be tested. Runbook describes service start order, decision makers, failover conditions і failback steps.

Практичний чеклист

  1. List services and prioritize: ERP, AD/LDAP, DNS, mail, databases, files, apps and monitoring.
  2. For every service define RPO, RTO, dependencies, data size and minimal startup resources.
  3. Choose method: backup, replication, standby VM, private cloud or colocated customer hardware.
  4. Prepare runbook: startup order, network, DNS, firewall, access, communication and decision criteria.
  5. Test DR at least partially and record real recovery time.

Найчастіші питання

Is backup enough for DR?

Not always. If services must start quickly, you need alternate environment, network and startup-order plan.

Can Proxmox be included in DR?

Yes, but backup/replication tools, storage, network and test procedure must fit installation.

Can DR run in DataHouse?

Yes. Use backup repository, private cloud, dedicated servers, colocation or private colocation room.
