CloudStack Storage Support: ZFS, QCOW2, LINSTOR, NFS — and Everything Else

Jan 20, 2026By Sendense Engineering

CloudStack is a service‑provider platform. Storage diversity is part of the point.

But most backup products treat “CloudStack support” as a checkbox: they back up VMs, then quietly fall apart when your storage backends aren’t identical across zones, clusters, and customers. Sendense is built for CloudStack realities: multiple storage backends, at scale, with consistent backup, restore, and replication outcomes.

ZFS: full integration, fully optimized
QCOW2: full integration, fully optimized
LINSTOR: full integration, fully optimized
NFS: full integration, fully optimized
Everything else: high‑speed guest‑agent method

Replication is storage‑agnostic

Your DR and migration strategy should not depend on a specific storage backend. Sendense replication to CloudStack is designed to be storage‑agnostic. You can land workloads into CloudStack without pinning to one storage choice, allowing you to operate mixed backends across clusters/zones without breaking the replication model.

No matter how you back up, you get the platform advantages:

  • Security by disaggregation
  • AES-256-GCM Encryption
  • AsureDense Evidence
  • Compliance Reporting
  • Immutability & Legal Holds
  • File Recovery Search + UX
