Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Spanning Backup

  • No pricing published; requires quote request
  • Pricing is customizable based on data volume and service changes

Veeam Kasten for Kubernetes

  • Licensing is per worker node, so clusters designed with many small nodes for scheduling flexibility pay considerably more than the same capacity in fewer large nodes.
  • The free Starter edition is scale limited and community supported, so it works for evaluation and small clusters but there is no gentle upgrade path when production grows past the limit.
  • Backup performance depends on the underlying CSI driver snapshot capability, so on storage without proper CSI snapshot support it falls back to slower generic copying.
  • Restores into a different cluster need matching custom resource definitions and operator versions present beforehand, so cross-cluster mobility is less automatic than the marketing suggests.
  • Kasten protects Kubernetes only, so organisations with mixed virtual machine and container estates run it alongside a separate backup product and manage two retention policies and two sets of evidence.
