Trilio Alternative: How Storware Compares for OpenStack Backup and Disaster Recovery

Trilio has been part of the OpenStack backup conversation for a decade. It protects workloads from inside the cloud, through Keystone and a Horizon plugin, and that design suits many teams. It also defines the trade-offs.

If you are evaluating a Trilio alternative, the useful question is not which product ticks more boxes. It is where your recovery tooling lives when the cloud it protects is degraded, how many platforms it must cover over the next five years, and how predictable its cost stays as you grow.

This comparison sets Storware Backup and Recovery 8.0 for OpenStack against Trilio for OpenStack (T4O) 6.2 on those terms. It is based on each vendor’s public documentation as of October 2026.

In short:

• Architecture. Trilio runs inside OpenStack and relies on its Keystone authentication and Horizon UI. Storware runs as an independent backup and recovery platform with its own console, plus a Horizon plugin for self-service.
• Coverage. Trilio for OpenStack protects OpenStack. Storware protects OpenStack alongside VMware, Nutanix AHV, Proxmox VE, OpenShift Virtualization and more, under one license.
• Release support. Storware 8.0 supports OpenStack 2023.1 Antelope through 2026.1 Gazpacho. Trilio 6.2’s published matrix reaches 2025.2 Flamingo (Kolla).

Why OpenStack teams look for a Trilio alternative

Most teams that start looking are not unhappy with OpenStack backup as such. Their environment has changed around it. Five situations come up repeatedly in our conversations with cloud operators and enterprise architects.

1. OpenStack is no longer the only platform. VMware exits, edge clusters on Proxmox or Nutanix, and OpenShift Virtualization projects leave most organisations running several hypervisors at once. A backup tool scoped to one platform means a second and third tool, each with its own policies, retention and audit trail.

2. Recovery must work when the cloud does not. A backup layer that authenticates through Keystone and is operated through Horizon shares the fate of the control plane it protects. During a serious outage or a compromise, that is exactly the moment you need it.

3. Upgrades should not wait for the backup vendor. OpenStack ships two releases a year. Teams moving to 2026.1 want their data protection to be supported on day one, not after the next backup release.

4. Data sovereignty is now a procurement criterion. Under NIS2, DORA and national cloud strategies, European operators increasingly ask where the vendor is based and which jurisdiction governs it. Storware is headquartered in Warsaw; Trilio is headquartered in the United States.

5. Cost has to stay predictable. Adding a platform, a migration path or a new storage target should not trigger a new licence negotiation.

Storware vs Trilio for OpenStack: side-by-side

The biggest differences sit in architecture and scope, not in basic backup features. Both products take agentless, incremental backups of OpenStack instances and restore them with new flavors and networks.

Five differences that matter in production

1. Recovery that does not depend on the cloud it protects

Trilio’s management plane is OpenStack itself: users authenticate through Keystone and work in Horizon. That is convenient day to day. It also means a Keystone or Horizon outage, or a compromised control plane, can take your recovery tooling down with it.

Storware runs as a separate platform with its own console and role-based access control. The Horizon plugin gives project users self-service backup and restore, but administrators never depend on it. Recovery plans define in advance which instances are restored, from which backup and to which target. They execute in one action and double as regular recovery tests.

Why it matters: business continuity standards and DORA expect recovery capabilities to be tested and usable during the disruption itself, not after the platform is back.

2. One platform for a multi-hypervisor estate

Few OpenStack clouds stand alone. Storware protects OpenStack, VMware, Nutanix AHV, Proxmox VE, OpenShift Virtualization, Hyper-V, oVirt and OLVM with the same policies, retention rules and reporting, under one universal licence. There are no per-platform fees or feature tiers.

During a VMware exit this means both sides of the transition stay protected by one tool. VMware workloads are backed up as usual and can be recovered to OpenStack; Citrix Hypervisor and XCP-ng workloads can be recovered to OpenStack the same way.

3. Ceph-native incremental backups

Ceph RBD backs most production OpenStack clouds. Storware’s disk attachment strategy selects the incremental method per volume automatically: native changed-block tracking for Ceph RBD and Pure Storage, checksum-based processing for other Cinder backends. Only changed blocks are read and transferred, which shortens backup windows and reduces load on production storage.

4. Day-one support for current OpenStack releases

Storware Backup and Recovery 8.0 supports OpenStack 2026.1 Gazpacho, alongside Red Hat OpenStack Platform 17.1 and 18.0 and Canonical OpenStack. Teams can plan upgrades around their own roadmap instead of their backup vendor’s.

5. Layered protection against ransomware

Immutability is necessary but not sufficient on its own. Storware combines Object Lock and Retention Lock on S3-compatible storage, the isoLayer air-gapped destination, and tape for offline copies. Together they support a 3-2-1-1-0 strategy without additional products. See Immutable and Air-Gapped Backup Security.

When Trilio is the right choice

A fair comparison names the other side’s strengths. Trilio is a reasonable fit when:

• Your estate is OpenStack only and is expected to stay that way, so multi-platform coverage has no value.
• You want backup deployed with the cloud itself, through the same tooling your distribution uses, and you accept that it shares the control plane.
• In-place rollback is your main recovery pattern. Trilio’s in-place restore rewrites data on existing volumes when the instance is still present. Storware restores to new volumes instead.
• You already standardise on Trilio for Kubernetes and OpenShift and value one vendor for those two product lines.

If two or more of the five situations earlier in this article apply to you, a platform designed for multi-vendor environments will usually serve you better over a five-year horizon.

How to evaluate a Trilio alternative: a 7-point PoC checklist

Run any candidate through the same proof of concept on your own infrastructure. These seven tests separate a working backup from a working recovery.

1. Control-plane outage test. Stop Keystone or Horizon in a test region. Can you still start and complete a restore?
2. Release coverage. Is your current OpenStack release supported, and is the next one on the vendor’s roadmap?
3. Ceph incremental efficiency. Measure data read and transferred for a second backup of a busy Ceph-backed instance.
4. Full recovery plan. Restore a multi-instance application to a different project or cluster in one action, then time it against your RTO.
5. Tenant isolation. Confirm project users see only their own instances and backups, across multiple Keystone domains.
6. Ransomware scenario. Try to delete or modify a locked backup as an administrator. Confirm an isolated copy exists.
7. Cost at year three. Price today’s estate, then add one more hypervisor and 30% more data.

Storware offers a 60-day trial with all features except V2V migration, so you can run the full checklist before you commit.
