When teams shortlist Kubernetes backup tools, the conversation almost always ends up at the same three: Velero, Kasten K10, and Portworx PX-Backup. They cover the most common buying patterns - open source operator-led (Velero), commercial GUI-driven (Kasten), and stateful-workload focused (Portworx) - and they’re the three most-searched comparisons in the K8s backup space.
This post compares them head-to-head across the seven dimensions that decide the buy. If you’re still earlier in the evaluation, our 9-tool Kubernetes backup comparison covers the wider landscape including CloudCasa, Trilio, Rubrik, and Cohesity.
Last updated: June 2026
TL;DR verdict
| Winner for… | Tool | Why |
|---|---|---|
| Lowest cost | Velero | Free and open source; you pay only for storage and your team’s time |
| Best UI and ops experience | Kasten K10 | Strongest dashboard, multi-cluster manager, named support |
| Stateful workloads (databases) | Portworx PX-Backup | App-aware by default for databases on K8s |
| Small clusters (under 5 nodes) | Kasten K10 Free Edition | Free tier is genuinely useful for small footprints |
| Multi-cloud, no vendor lock-in | Velero | Works across every cloud; no commercial relationship required |
| Ransomware and compliance | Kasten K10 | Strongest combination of immutability, anomaly detection, and audit features at the mid-market price point |
| Already on Pure Storage | Portworx PX-Backup | Native integration, single vendor, bundled value |
If you only read this section: Velero if you have the operations capacity to run it, Kasten K10 if you want a turnkey commercial product, Portworx PX-Backup if your workloads are heavily stateful and you want storage and backup from one vendor.
The rest of this post explains why.

| Ecosystem | Largest community | Strongest commercial ecosystem | Tied to Portworx platform |
The seven rounds below explain each row.
Round 1: Application consistency
This is the round that decides most evaluations. Application-consistent backups mean the data on persistent volumes is in a state the application can recover from - the database has flushed its write-ahead log, the message queue has drained, the in-memory state has been persisted.
Velero
Velero handles application consistency through backup hooks - annotations on pods that tell Velero to execute commands before and after the volume snapshot. For example, freezing a PostgreSQL instance with SELECT pg_start_backup() before snapshotting and pg_stop_backup() after.
This works, but it puts the burden on the operator:
- You write the hooks per application
- You maintain them as applications change
- You test them, because a broken hook silently produces broken backups
For the most common databases, Velero plus Kanister (open source from Kasten) is a workable pattern. Kanister provides pre-built “blueprints” for PostgreSQL, MySQL, MongoDB, Cassandra, Elasticsearch, Kafka, and others. You install both, and Kanister handles app-consistency while Velero handles K8s state and PV snapshots.
Kasten K10
K10 has app-consistency by default through Kanister blueprints (the same Kanister Velero users install separately). Out of the box, K10 detects common stateful applications and applies the right blueprint.
For applications not in the default catalog, you can write custom blueprints or hand off to generic volume snapshot mode. The catalog itself is broader than vanilla Kanister, with K10-specific additions and improved integration with the K10 control plane.
Portworx PX-Backup
Portworx takes a different approach: Stork (storage orchestrator from Portworx) provides app-aware backup primitives that PX-Backup builds on. App rules let you define pre and post snapshot commands per application, and Portworx maintains a catalog of rules for common databases.
The strongest fit is when you’re using Portworx storage underneath - the app-consistency, snapshot, and replication primitives are tightly integrated. With non-Portworx storage, you still get app-aware backups but lose some of the deeper storage-level capabilities.
Round 1 winner
Tie between Kasten K10 and Portworx PX-Backup for out-of-the-box experience. Velero (alone) requires more work; Velero plus Kanister gets you close to Kasten K10’s experience but with more setup. For pure app-consistency, K10 and PX-Backup are interchangeable at the feature level; pick by other factors.
Round 2: Pricing and TCO
The pricing models are very different, which makes a direct comparison hard. Here’s how to think about it.
Velero
License: free. What you pay for:
- Object storage for backups (S3 / Azure Blob / GCS / on-prem)
- The operations time to run it (this is the part most teams underestimate)
- Any commercial support contract (Red Hat OpenShift Data Foundation if you’re on OCP, or third-party support like Open Source Solutions)
For a 50-node cluster with 5 TB of backups, the AWS storage cost might be $115/month (S3 Standard) or $25/month (S3 Glacier Instant Retrieval) for the backups themselves, plus replication and egress for cross-region copies.
The total Velero TCO over 3 years is usually $0 in license, plus 5-20% of one engineer’s time for ongoing operations, plus storage.
Kasten K10
License: free for up to 5 worker nodes per cluster (no time limit). Commercial pricing kicks in beyond that.
Commercial pricing is per-worker-node, annual subscription. Public list pricing in 2026 starts around $400-600 per node per year for the Foundation edition and goes higher for Enterprise. Multi-cluster, advanced security, and SaaS Manager are higher tiers.
For a 50-node single cluster: roughly $20,000-30,000 per year list price for Foundation tier. Enterprises typically negotiate from there.
Operationally, K10 is lighter to run than Velero in terms of hours-per-week. The license cost buys you back the ops time.
Portworx PX-Backup
License: commercial only, sales-led pricing, typically per-node. Pricing is not publicly listed and varies significantly based on the broader Portworx commitment.
Portworx PX-Backup as a standalone purchase is less common than the bundle: PX-Backup plus Portworx Enterprise storage. The bundle pricing is more attractive than buying PX-Backup alone.
For a 50-node cluster running PX-Backup standalone, expect list pricing in a similar range to Kasten K10 Enterprise tier. The full Portworx stack is meaningfully more.
Round 2 winner
Velero wins on direct license cost. Kasten K10 wins on operational TCO if you assign realistic dollar value to ops time. Portworx is best value when bundled with the rest of the Portworx platform.
For a 50-node cluster over 3 years (license + storage + ops time):
- Velero: ~$50,000-80,000 (mostly ops time)
- Kasten K10: ~$70,000-110,000 (license + storage + lighter ops)
- Portworx PX-Backup standalone: ~$90,000-140,000 (license-heavy)
These are directional. Real pricing requires actual quotes.
Round 3: Multi-cluster and fleet management
If you have 3+ Kubernetes clusters, fleet management matters as much as per-cluster features.
Velero
Velero is per-cluster. Each cluster has its own Velero install, its own backup schedule, its own object storage location, its own credentials.
For multi-cluster fleets, the common patterns:
- GitOps the Velero configuration so backups are consistent across clusters
- Centralized monitoring via Prometheus + Grafana watching every cluster’s Velero metrics
- Custom dashboarding to give the platform team fleet-wide visibility
This works but it’s homemade. There’s no Velero-native “show me backup health across 20 clusters” view.
Kasten K10
K10 has a Multi-Cluster Manager that gives you a single pane across registered clusters. You can:
- See backup health and storage usage across the fleet
- Apply policies centrally and push them to clusters
- Initiate cross-cluster migrations and restores
- Manage RBAC for the multi-cluster view
For fleets above 5-10 clusters, this is meaningfully easier than the Velero approach.
Portworx PX-Backup
PX-Backup has a central control plane that registers multiple clusters. The experience is similar to Kasten K10 Multi-Cluster Manager - fleet-wide policies, central visibility, cross-cluster operations.
The strongest fit is when Portworx Storage is deployed across the fleet too. With heterogeneous storage backends across clusters, you still get the backup orchestration but lose some of the storage-layer benefits.
Round 3 winner
Kasten K10 and Portworx PX-Backup tied for multi-cluster experience. Velero requires you to build it. For fleets above ~10 clusters, K10 or PX-Backup save real platform team time.
Round 4: Restore experience and DR readiness
A backup that you can’t actually restore from is not a backup. The restore experience varies dramatically across these three.
Velero
Restore is CLI-driven. The command structure is straightforward:
velero restore create my-restore --from-backup my-backupWhat works well:
- Granular restores (selected namespaces, selected resources, selected labels)
- Restore-to-different-cluster, restore-to-different-namespace
- Pre and post restore hooks
What’s harder:
- Complex restores at 3 AM during an incident. CLI muscle memory only goes so far when you’re tired
- App-consistency on restore requires your hooks to handle it (or Kanister blueprints)
- Order-of-restore dependencies for stateful apps need manual orchestration
- Cross-cluster restore with re-IP, re-storage-class requires resource transformations
For trained teams, Velero restore is fine. For mixed-skill teams under incident pressure, the CLI surface area is a real challenge.
Kasten K10
K10 restore is GUI-driven with a strong API underneath. The experience:
- Browse application backups in the UI, pick the restore point, click restore
- Migration wizard handles cross-cluster restores including resource transformations
- Pre and post restore actions via Kanister blueprints
- RBAC controls who can restore what (audit-friendly)
The GUI matters more than people admit. Restore drills are easier to run when the team can perform them without deep CLI knowledge. Compliance evidence is easier when there’s a clear audit trail.
Portworx PX-Backup
PX-Backup restore is also GUI-driven, with similar capabilities to Kasten K10. App-aware restore for the supported databases handles the consistency piece automatically.
Where PX-Backup particularly shines is storage-aware restore - if you’re using Portworx storage on both source and destination, the restore can leverage storage-layer features (snapshots, replication) for faster restore than file-level copying.
Round 4 winner
Kasten K10 for general restore experience, Portworx PX-Backup for stateful-app restores with Portworx storage, Velero if your team has the operational maturity to operate the CLI under pressure.
This is the round where commercial tools earn their license fees. The cost difference is real, but so is the difference in restore-during-incident experience.
Round 5: Ransomware and immutable storage
Ransomware protection has become a board-level concern for K8s estates as much as for traditional infrastructure. Each of the three takes a different approach.
Velero
Velero relies on the underlying object storage for immutability. S3 Object Lock, Azure Blob immutable storage, and GCS retention policies all work with Velero - configure the bucket correctly, and backups can’t be modified or deleted for the retention period.
What Velero doesn’t do natively:
- Anomaly detection (unusual data change patterns, mass deletion attempts)
- Encryption of backup contents beyond what object storage provides
- Ransomware-specific alerting
You can build these with the Kubernetes security stack around Velero, but they’re not in the box.
Kasten K10
K10 has the strongest built-in ransomware story of the three:
- Immutable backups with object lock support
- Anomaly detection that flags unusual change patterns (mass file modifications, suspicious encryption)
- Integration with security tools (Sysdig, Falco, others) for runtime threat context
- Air-gapped backup destinations for ransomware recovery scenarios
For organizations where ransomware is a named risk, K10’s security features are a real differentiator.
Portworx PX-Backup
PX-Backup includes immutability and encryption. The ransomware-specific tooling is less prominent than K10’s, but the foundational controls are present.
For organizations already on Pure Storage with the broader Pure security tooling, the integration story is cleaner. Standalone PX-Backup for ransomware-focused use cases is workable but not the strongest pick.
Round 5 winner
Kasten K10 for ransomware-specific features at the mid-market price point. Velero with the right object storage configuration covers the basics but requires more assembly. PX-Backup is strong when paired with the broader Pure Storage security stack.
Round 6: Operational footprint and complexity
How much does each tool actually cost in operational complexity?
Velero
Minimal footprint:
- 1 namespace (
velero) - 1-2 deployments (server, optional CSI controller)
- A handful of CRDs (Backup, Restore, Schedule, BackupStorageLocation, etc.)
- ~100-500 MB memory, low CPU at idle
The footprint is small. The operational complexity is high because you own everything: monitoring, alerting, hook maintenance, restore testing, version upgrades.
For teams with platform engineering maturity, this is acceptable. For teams without it, the “free” tool becomes expensive in unplanned outage hours.
Kasten K10
Heavier footprint:
- 1 namespace (
kasten-io) - 10-15 deployments and statefulsets
- 30+ CRDs
- 4-8 GB memory across the K10 stack, several CPU cores at idle
In exchange:
- Built-in monitoring, alerting, and reporting
- Web UI for daily operations
- Vendor support contract for issues
- Upgrade flows that don’t require deep operator knowledge
For most enterprises, the heavier footprint is worth the lower operational burden. For very small clusters, K10’s footprint can be larger than the rest of the cluster.
Portworx PX-Backup
Medium-heavy footprint, especially when combined with the Portworx CSI driver and Stork:
- Multiple namespaces (
portworx,px-backup) - Portworx storage agents on each node
- PX-Backup central components
- Several GB memory, depending on workload count
Combined Portworx + PX-Backup is a significant install. Standalone PX-Backup (without Portworx storage) is lighter but loses some integration benefits.
Round 6 winner
Velero for smallest footprint, Kasten K10 for lowest day-to-day operational complexity, Portworx PX-Backup for biggest install but tightest storage integration.
Round 7: Ecosystem and integrations
How well does each integrate with the rest of your stack?
Velero
Largest open source ecosystem. Velero integrates with:
- Every major cloud (AWS, Azure, GCP, Oracle, Alibaba)
- CSI snapshot mechanism (any storage driver that implements it)
- GitOps tools (ArgoCD, Flux can manage Velero configuration)
- Prometheus for metrics
- Most observability platforms via Velero’s exposed metrics
The community is large, the documentation is solid, and you’ll find StackOverflow answers for almost any error.
Kasten K10
Strongest commercial ecosystem. Kasten K10 integrates with:
- The wider Veeam ecosystem (repositories, immutability features)
- Major Kubernetes distributions (Vanilla, OpenShift, Rancher, EKS, AKS, GKE)
- Security tools (Sysdig, Falco)
- ITSM (ServiceNow, others)
- Cloud providers’ KMS for encryption
The commercial ecosystem matters more in enterprises than individual contributors realize. Compliance, procurement, and audit teams all want clear vendor relationships.
Portworx PX-Backup
Tightest integration with the Portworx platform. Strongest for organizations using:
- Portworx Enterprise storage
- Portworx Database-as-a-Service
- Portworx Autopilot for capacity automation
- The broader Pure Storage ecosystem
Outside Portworx-native shops, PX-Backup is workable but the integration story is less compelling than Kasten K10’s broader commercial reach.
Round 7 winner
Velero for open source ecosystem breadth. Kasten K10 for commercial / enterprise ecosystem depth. Portworx PX-Backup for Portworx and Pure Storage shops.
Decision tree: which one for which scenario
Picking by the most common patterns we see:
“We’re a small team, cost-sensitive, already comfortable with Kubernetes operations.” → Velero, with Kanister blueprints for any stateful workloads.
“We’re mid-market or enterprise, want a polished product, will pay for support.” → Kasten K10. Start with Free Edition on smaller clusters to evaluate.
“We run heavy stateful workloads on K8s and want storage and backup from one vendor.” → Portworx PX-Backup, ideally bundled with Portworx Enterprise.
“We have 10+ clusters across regions and need fleet management.” → Kasten K10 Multi-Cluster Manager or Portworx PX-Backup central control plane. Not Velero (you’d build it yourself).
“Ransomware is a board-level concern.” → Kasten K10 for the best out-of-box features at a sensible price point.
“We’re already a Veeam shop for VM backup.” → Kasten K10 for the integration story alone.
“We’re already on Pure Storage.” → Portworx PX-Backup.
“We have under 5 worker nodes per cluster.” → Kasten K10 Free Edition if you want the GUI, Velero if you don’t.

Common evaluation pitfalls
Mistakes that show up across the three:
- Evaluating without an actual restore. Demo backups are easy. Restoring under realistic conditions is where tools differ. Make a restore drill part of every evaluation.
- Not testing app-consistency. Snapshot a busy database mid-write and see if the restored database starts cleanly. Most teams skip this.
- Ignoring multi-cluster from day one. A tool that works for 1 cluster but doesn’t scale to 10 is technical debt waiting to happen.
- Comparing list prices without TCO. The “free” tool has real ops costs. The expensive tool may save engineer hours.
- Skipping the vendor financial-stability check. Backup is a multi-year commitment. The vendor needs to be around in 5 years.
- Backing up clusters but not external data. Kubernetes backup tools cover K8s state and PVs. Your RDS, external S3, and SaaS data have separate backup stories.
For the wider DR strategy, our Kubernetes disaster recovery playbook covers what to do when backups have to be used.
FAQ
Which is best, Velero or Kasten K10?
Depends on your team. Velero is free, open source, and requires operational maturity to run well. Kasten K10 is commercial, GUI-driven, and easier to operate but costs money. If you have platform engineering capacity, Velero. If you want to buy time back, Kasten K10.
Is Kasten K10 built on Velero?
Not directly. Kasten K10 uses Kanister (also open source, originally from Kasten) for application data management, and the K10 architecture shares concepts with Velero. But K10 has its own backup engine, scheduler, and UI - it’s not “Velero with a GUI”.
Is Portworx PX-Backup tied to Portworx Storage?
PX-Backup can back up applications running on any CSI-compliant storage, not just Portworx. The strongest integration and features come when paired with Portworx Storage, but standalone use is supported.
Can I migrate from one of these to another?
Yes, but it requires careful planning. The K8s manifests are portable (they’re standard YAML), but the backup metadata, retention policies, and immutability settings don’t transfer between tools. The pattern is usually: run both in parallel for a transition period, validate the new tool’s backups and restores, then decommission the old one.
Which has the best free tier?
Kasten K10 Free Edition for up to 5 worker nodes per cluster, with no time limit and most features included. Velero is fully free for any cluster size. Portworx PX-Backup has trial periods but no production-grade free tier.
Which is best for OpenShift?
All three work on OpenShift. Red Hat’s own data protection product (OADP) is Velero under the hood, so it’s the path of least resistance for many OCP shops. Kasten K10 has strong OpenShift integration and is a common choice for enterprise OCP customers. Portworx PX-Backup works but is less commonly chosen on OpenShift unless Portworx Storage is already deployed.
Which is best for EKS, AKS, or GKE?
All three work on all three managed Kubernetes services. Velero is the most common choice on EKS and GKE due to its open source nature. Kasten K10 is common in enterprise EKS, AKS, and GKE deployments. Portworx PX-Backup is chosen when stateful workloads dominate. For the deeper EKS context, see our EKS migration guide which covers the backup story as part of landing zone design.
How much does Kasten K10 cost?
Kasten K10 pricing is per-worker-node, annual subscription, starting around $400-600 per node per year for the Foundation edition in 2026 list pricing. Enterprise tier and multi-cluster features are higher. Public pricing is indicative; enterprises typically negotiate. Free Edition covers up to 5 nodes per cluster with no payment required.
Does Velero support application-consistent backups?
Yes, via backup hooks (pod annotations that run pre and post snapshot commands) or by pairing with Kanister. Out of the box, Velero does PV snapshot but not app-quiesce. Adding Kanister gets you app-consistency for the most common stateful applications.
Can these tools restore to a different cluster?
Yes, all three support cross-cluster restore. The experience varies: Velero requires manual resource transformations for things like storage classes and IP ranges. Kasten K10 has a migration wizard. Portworx PX-Backup has cross-cluster restore that’s tightest when Portworx Storage is on both ends.
Which is best for ransomware protection?
Kasten K10 has the strongest built-in ransomware features (immutability, anomaly detection, integration with security tools). Velero plus correctly configured S3 Object Lock covers immutability but lacks the anomaly detection layer. Portworx PX-Backup is in between.
Need help picking and operating Kubernetes backup?
The tool selection is the visible part of the decision. The harder part is operating whichever tool you pick: app-consistent policies for every stateful workload, cross-region targets that survive blast radius, restore drills that prove the backups work, and the runbooks for the incident at 3 AM.
