Disaster recovery you can rehearse.

Proxmox VE offers built-in ZFS replication (pvesr, between nodes of one cluster), Ceph's own RBD mirroring if you set it up yourself, and backups via Proxmox Backup Server, but it has no SRM/Zerto-class DR orchestration: no recovery plans, non-disruptive DR testing, or one-click failover. Asternodis adds that layer, and works on storage backends Proxmox can't natively replicate.

You set a target per guest, from about 1 minute up, and Asternodis replicates continuously toward it, on any storage backend, not just ZFS or Ceph. The storage support matrix lists the validated storage backings. What you actually achieve depends on how much the guest writes and how fast the link between your sites is.

Near-instant. While you run at the recovery site, Asternodis reverse-replicates your changes back to the primary continuously. When the primary is healthy again, failback applies only the small delta accumulated since (often a few megabytes, in seconds) instead of re-copying the whole disk.

Yes. Asternodis retains multiple integrity-verified, point-in-time recovery points, so you can fail over to a known-good moment rather than the latest (possibly-encrypted) state. A background scrub re-verifies each point over its whole retention life and quarantines any that silently rot, and a change-rate anomaly detector pauses replication on the signature of mass encryption to preserve a clean pre-attack point.

Yes. Asternodis brings the DR capabilities teams expect from VMware Live Site Recovery/SRM and Zerto (replication, DR testing, recovery plans, failover and failback) to Proxmox VE, at a fraction of the price.

No. Control traffic between the two controllers rides one mutually authenticated TLS channel, and replication data moves node to node over separately encrypted links: mutually authenticated TLS for VM disks, SSH for containers and ZFS send. You open the ports the install guide lists between the sites, or ride an existing site-to-site VPN or Tailscale if you prefer.

Home Lab (non-commercial) is $99/year per DR Site Pair, with unlimited protected nodes. Home labs are never node-capped. Business licensing starts at $995/year for one pair covering up to 4 protected nodes, $2,495 for up to 12, and $4,995 for unlimited nodes. Multi-pair packs for MSPs and multi-site estates run from $3,995 for 5 pairs to $14,995 for 25, with their node allowance pooled across all the pairs in the pack. A DR Site Pair is one production site paired with one recovery site. Every tier includes the full DR feature set.

Every tier includes the documentation and the community forum. Business and above add email support with a next-business-day response target (Monday to Friday, US Eastern) and a disaster escalation channel for when a site is actually down. Support is handled in writing, which during an incident is usually better anyway: you get commands you can paste and a record you can drop into your own post-incident review. Enterprise and multi-site agreements can be arranged to fit how your team works.

A Proxmox node that hosts at least one VM or container Asternodis is protecting. Nodes at the recovery site don't count, and neither do nodes running only guests you haven't protected, so you pay for the footprint you actually cover, not the size of your clusters. Asternodis shows the current count on its License page.

That's fine: a pack's node allowance is pooled across every pair in it, not fixed per pair. A 5-Pack includes 20 protected nodes, so one client running 8 and four running 3 fits comfortably. You only need a bigger pack, or a custom agreement, when the whole pool runs out.

It's the same software, fully featured, either way. Home Lab is the discounted non-commercial tier for personal home labs, learning, and testing, not for running or protecting a business. Business licensing covers any commercial, production, or organizational use.
