RPO and RTO for Proxmox: setting recovery targets that make sense
Two numbers define your disaster recovery: how much data you can lose, and how long recovery can take. Here's how to think about RPO and RTO for Proxmox VE.
RPO: how much data can you lose?
Recovery Point Objective is the maximum acceptable data loss, measured in time. A 10-minute RPO means that after a disaster, you might lose up to 10 minutes of changes. RPO is driven by your replication interval: replicate every 10 minutes, and your RPO is about 10 minutes.
RTO: how fast must you recover?
Recovery Time Objective is how long recovery may take before the impact is unacceptable. RTO is driven by orchestration: manual recovery from documentation is slow and error-prone; a tested recovery plan that boots VMs in the right order, re-maps networks, and runs health checks is fast and repeatable.
Choosing targets per workload
- Critical databases / core apps: tight RPO (minutes) and low RTO — replicate frequently, automate recovery.
- Standard business VMs: a 10-minute to 1-hour RPO is usually fine.
- Dev/test: looser targets — or protect only what matters.
Not every VM needs the same targets. Group workloads and set RPO/RTO to match their business impact.
Hitting your targets on Proxmox
To meet a low RPO you need frequent, efficient replication — including on storage Proxmox can't natively replicate. To meet a low RTO you need recovery plans and, ideally, non-disruptive DR testing so you know recovery actually works. ProxDR provides both: near-continuous replication on any storage, plus recovery plans, test failover, and one-click failover/failback. See the Proxmox disaster recovery guide for the full picture.
