CubeDPX is an enterprise data protection solution for CubeCOS, Bigstack's open-source cloud platform for OpenStack and Kubernetes. It provides cloud-native, application-consistent backup and recovery, as well as a VMware migration toolkit, all through the same management interface you already use for virtualization, storage, and networking.
This simplifies the transition from VMware to CubeCOS. You skip the separate backup server, the extra console, and the second support relationship. CubeCOS provides one policy-driven data protection workflow. Granular restore options include self-service and tenant-wide recovery via one-click, selective, or in-place restores. These options help you meet strict Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).
CubeDPX brings workload migration, data protection, and recovery to your existing platform, eliminating the need for a separate backup server. During a VMware exit, unprotected data poses one of the biggest risks. Backup software itself isn't hard to find. The challenge lies in integrating a separate backup product into a new platform amidst an already complex migration. This process involves setting up and patching another server, deploying agents into virtual machines (VMs), or reconfiguring hosts. Additionally, it requires tracking a license with its own renewal cycle and contacting a second vendor, rather than the familiar team, when it's time to recove
CubeCOS is an open-source alternative to VMware that offers transparent control over your infrastructure and costs. Bigstack enterprise support is available after the switch. CubeDPX extends this support to data protection by providing backup and recovery for your migrated workloads from day one. The same team familiar with your CubeCOS deployment will support you.
CubeDPX quiesces workloads before capturing them. With qemu-guest-agent running in the guest, it flushes databases and multi-tier applications to a clean, restorable state, instead of the crash-consistent state a disk-level snapshot alone gives you. That means restores come back in a known-good state rather than needing crash recovery. After the initial full backup, only changed blocks are captured in incremental snapshots, so you can back up more often without your storage footprint growing in step.
See the full backup capability page for details.
CubeDPX manages data protection through policies that determine the schedule, retention period, and scope for each workload or tenant. Once configured, a policy runs on schedule. You can manage the policy through the same CubeCOS interface that your team already uses. There is no separate console to learn. For MSPs and carriers running multi-tenant clouds, this means that each tenant can perform self-service backups within their own boundaries, and operators can maintain central oversight of the entire environment.s
CubeDPX creates Write Once, Read Many (WORM) backups with object locking in S3-compatible object storage. During the retention period, no one can alter or delete those backups via the storage API — not even an attacker with stolen production or backup credentials. This feature helps you meet compliance, governance, and cyber insurance requirements that call for immutable backups. However, note that immutability requires an S3-compatible target; NFS targets do not support it.
The CubeDPX package includes the CubeCOS VMware Migration Toolkit. The toolkit's pre-migration validation and automated workflows identify issues before cutover. With backup and migration combined into one product, workloads are protected the moment they land on CubeCOS. This eliminates the need to wait to onboard them to a separate backup tool.
Your backup data is stored as open, portable QCOW2 disk images on NFS or S3-compatible storage systems that you own and manage. Nothing leaves your environment to be stored in a third-party cloud or vendor-managed store. This makes CubeDPX ideal for organizations in finance, government, utilities, and service providers with strict data residency or sovereignty requirements.

These capabilities are not new to the backup market. What sets CubeDPX apart is that you don't need a second product to access them. Your team can manage backup and recovery from the same interface as the rest of the platform, with the same support team. This means there is only one interface to learn and one upgrade cycle to plan.
This follows Bigstack's approach of building CubeCOS as a complete, deployable cluster rather than a collection of components that someone else has to integrate. Depending on the environment and scope, CubeCOS can deliver costs up to 70% lower than VMware over a three-to-five-year contract period. Keeping backup inside the platform eliminates the need for a separate backup stack.
As David Safaii, the founder and chief technical evangelist at Trilio, put it: "Instead of stitching together components, customers get a ready-to-deploy platform, a consistent operational model, and a much faster path to production. Bigstack isn't just an alternative. It's a better economic and architectural model. With Trilio integrated directly into CubeCOS, customers get native backup and recovery."

CubeDPX is now available as an enterprise add-on for CubeCOS. It joins CubeCMP, which is used for cloud management, and CubeVDI, which is used for virtual desktops. Start with the free, open-source edition of CubeCOS today. When you need enterprise-grade backup, recovery, and ransomware-resistant protection without having to re-architect anything you've already deployed, add CubeDPX.
Are you evaluating a private cloud alternative to VMware? Are you already running CubeCOS and wondering how to protect it? Either way, CubeDPX provides native backup for a private cloud without a second vendor's stack.
Schedule a data protection demonstration to see how native backup, recovery, and VMware migration work inside CubeCOS. No separate backup vendor is required. Alternatively, download CubeCOS to start using the open-source edition.
No, CubeDPX is a native add-on to CubeCOS. You can manage it through the same user interface (UI) your team already uses. There is no need for a separate backup server or console.
CubeDPX uses the QEMU Guest Agent inside the guest to quiesce workloads before capturing them. This produces application-consistent backups instead of crash-consistent ones. This enables databases and multi-tier applications to be restored to a clean, known-good state. Without the guest agent, backups are crash-consistent.
Yes. CubeDPX creates Write Once, Read Many (WORM) backups with object locking in S3-compatible object storage. During the retention period, no one can alter or delete the backups through the storage API, even with stolen production or backup credentials. However, immutability requires an S3-compatible target, and NFS storage doesn't support it.
Backup data is stored as QCOW2 disk images on NFS or S3-compatible storage that you own and manage. Nothing is sent to third-party clouds or vendor-managed stores, making CubeDPX a good choice for organizations with strict data residency or sovereignty requirements.
Yes. It includes the CubeCOS VMware Migration Toolkit, which performs pre-migration validations and automated workflows to identify issues before cutover. Since backup and migration are part of the same product, migrated workloads are protected the moment they land on CubeCOS.
No. CubeDPX is an enterprise-level add-on that runs on top of CubeCOS. Start with the open-source version of CubeCOS, then add CubeDPX when your workloads require enterprise-grade backup, recovery, and ransomware-resistant protection. You won't need to redesign what you've already deployed. Book a data protection demo to discuss your environment.
