Keep Kubernetes stateful workloads recoverable across availability zones with near-zero RPO.
Simplyblock continuously streams block-level changes to durable object storage while serving production traffic from high-performance tiers. If an availability zone fails, you can restore volumes and snapshots in another zone quickly and consistently, with dramatically lower data-loss risk than periodic snapshot-based approaches.
The Challenge
Traditional backup workflows leave recovery gaps and require complex runbooks. Teams need a DR approach that minimizes data loss, restores consistently, and stays practical to operate.
Periodic backups can miss recent writes, creating unacceptable RPO gaps for transactional systems.
Databases, queues, and file-backed services can recover at different points in time without coordinated replay.
Runbook-heavy recovery across zones increases operational risk during already high-pressure incidents.
Teams avoid frequent simulations because staging realistic recovery tests is slow and disruptive.
The Approach
Continuous log-based protection and fast recovery mechanics designed for Kubernetes stateful workloads.
Simplyblock writes production data to performant storage while asynchronously streaming changes into a write-ahead log in object storage. This reduces recovery-point gaps to near-zero without relying on coarse snapshot schedules.
During an AZ outage, simplyblock reconstructs storage state from WAL data and snapshots so Kubernetes workloads can restart with consistent volume state, reducing recovery friction and data reconciliation work.
Use instant snapshots and clones to run repeatable recovery drills without impacting production traffic. Teams can validate RPO/RTO assumptions and improve runbooks continuously.
Key Benefits
Stronger resilience, tighter recovery objectives, and simpler operations for business-critical Kubernetes workloads.
Protect recent writes continuously and reduce data-loss exposure during availability-zone failures.
Restore databases and persistent services to coherent points in time with less manual reconciliation.
Use object storage-backed logs and tiered data placement to improve DR economics.
Replace fragile failover scripts with policy-driven workflows on a unified storage platform.
Simplyblock provides Kubernetes-native block storage for Multi-Availability Zone Disaster Recovery for Kubernetes, with predictable performance and simpler operations.
It uses a scale-out architecture and NVMe-over-TCP to deliver low-latency performance while scaling capacity and throughput as workloads grow.
Most teams begin with a phased rollout, validate workload behavior, and then migrate stateful services with minimal disruption.
