KubeSphere Backup

KubeSphere Backup is a cloud disaster-recovery service for protecting data across hybrid-cloud Kubernetes clusters. It supports backup and recovery across clouds and Kubernetes versions, with compatibility for various Kubernetes distributions and S3-standard object storage. CSI snapshot backups cover stateful applications such as MySQL, MongoDB, and Redis. Users can create and run data-protection tasks through a console without expertise in tools such as Velero. Listed use cases include responding to hardware or system failures, configuration errors, and improper operations, protecting multiple clusters, and moving application data between clouds. The free plan includes 2 protected applications, 3 days of retention, and a 10 GB hosted repository. Basic costs $65 a month and includes 100 protected applications, 14 days of retention, and 100 GB of hosted repository. Direct cluster connection requires the Kubernetes API server address in kubeconfig to be reachable over the public network; agent connection is an alternative. The repository access domain must meet AWS S3 standards. For Copy Volumes backups, the vendor advises disconnecting the database before backup to support consistency.

KubeSphere Backup combines cross-cluster protection with a console for configuring tasks and a free entry plan. Check the connection and storage requirements, and follow the database guidance for Copy Volumes backups.

KubeSphere Backup suits teams protecting data across Kubernetes clusters, including stateful workloads and multi-cloud environments. Its console may appeal to users who do not specialize in Kubernetes backup tools.

Overview

KubeSphere Backup is a cloud service for disaster recovery across Kubernetes clusters in hybrid-cloud environments. It suits teams protecting stateful applications and cluster resources across clouds or Kubernetes versions. Its console and cross-cluster coverage are useful, provided your cluster access and object storage meet its requirements.

Key features

KubeSphere Backup backs up and recovers data across Kubernetes clusters, including across clouds and Kubernetes versions. That range suits teams preparing for hardware or system failures, configuration errors, or operational mistakes, and those moving application data between clouds. Persistent volumes and cluster resources are covered, with app-consistent backup support.

For stateful applications, CSI snapshot backup supports workloads such as MySQL, MongoDB, and Redis. Users can create and execute protection tasks through a console, which may be a better fit for teams that want a managed workflow than direct use of Kubernetes backup tools such as Velero. The console does not eliminate setup constraints: direct cluster connection requires the API server address in kubeconfig to be reachable over the public network, though an agent connection is an alternative. The object-storage repository domain must be compatible with AWS S3 standards.

Copy Volumes backups require care with databases. The vendor advises disconnecting the database before backup to protect consistency and integrity, a step that may complicate protection workflows for systems that need to stay online.

Pricing

The Free plan costs nothing and covers 2 protected applications, 3 days of retention, and a 10 GB hosted repository. It is a small-scale way to assess the service, but its application cap and short retention leave little room for broader or longer-term protection.

Basic costs $65 a month, billed USD 65/month, and raises capacity to 100 protected applications, 14 days of retention, 100 GB of hosted repository space, and 3 resource templates. It is the entry paid tier for modest environments. Standard costs $200 a month, billed USD 200/month, and includes 500 protected applications, 30 days of retention, 500 GB, and 10 resource templates. It is better suited to larger deployments that need a month of retention.

Enterprise costs $340 a month, billed USD 340/month, and provides 1,500 protected applications, 90 days of retention, 1 TB, and unlimited resource templates. Its longer retention and higher limits target substantial environments. The Free subscription is free, billed as a long-term free subscription; its first 30 days include Standard subscription functionality, 500 protected applications, and 500 GB of hosted storage. Exclusive has custom pricing, with customizable application limits, retention, and repository capacity, plus 24 x 7 support.

A free trial is offered. The paid tiers increase application, retention, storage, and template limits, so the right choice depends on how much data must be retained and how many applications must be protected. Maximum retention is 14 days.

Platforms

KubeSphere Backup is offered on the web and uses a cloud deployment model. Kubernetes support includes persistent-volume backup, cluster-resource backup, and app-consistent backup.

Who it's for

This is a sensible fit for teams managing Kubernetes across multiple clouds or versions that want a console for backup tasks and recovery. Teams should confirm that direct public-network access or an agent connection works for their clusters, and that their repository domain meets AWS S3 standards. It is less suitable for workflows that cannot accommodate disconnecting databases during Copy Volumes backups.

Pros and cons

Pros

• Cross-cluster protection across clouds and Kubernetes versions supports multi-cluster recovery and cloud-to-cloud migration.
• CSI snapshots cover stateful applications including MySQL, MongoDB, and Redis.
• A task console gives teams a managed way to configure and execute protection without direct expertise in tools such as Velero.
• The Free plan provides a hosted repository, while higher tiers scale to 1 TB and 90 days of retention.

Cons

• The Free plan is capped at 2 applications, 3 days of retention, and 10 GB, which limits its role in ongoing protection.
• Direct connection requires a publicly reachable Kubernetes API server address, unless using the agent option.
• Repository access domains must be compatible with AWS S3 standards.
• Copy Volumes backups call for disconnecting the database to preserve consistency and integrity.

Alternatives

Velero is a free option for teams comfortable with an open-source Kubernetes backup tool and cloud or on-premises use. Afi Kubernetes Backup may suit teams comparing a paid product with free licenses available by request for environments protecting fewer than 10 nodes.

Bacula Enterprise is a paid alternative with annual pricing based on secured endpoint count and support response time. KubeStash offers free use on supported Kubernetes engines and a 30-day free license to try.

Bnkr is another free option. Rancher Backup and Restore Operator is a free project for Linux and self-hosted environments. Google Kubernetes Engine is a paid Kubernetes platform with a free tier that provides $74.40 in monthly credits per billing account for zonal and Autopilot clusters. Veeam Agent for Mac is a macOS backup alternative whose free edition is limited to one backup job and cannot back up directly to object storage.

Verdict

Choose KubeSphere Backup if you need cloud-managed protection across Kubernetes clusters and want to configure tasks through a console, especially for stateful workloads. Its cross-cloud scope and tiered capacity are the strongest reasons to consider it. Look elsewhere if your workflow cannot meet the connection or S3-compatible storage requirements, or if Copy Volumes backups cannot accommodate database disconnection.
