  • Ontap 9.5+
  • FlexCache

Answer

  • No, backup option is not available for FlexCache volumes on Ontap.
  • Snapshot and snapmirror both are not supported for FlexCache.
  • This is because FlexCache is intended to allow for a volume to cache only data in active use, what is called the "working set" of data
  • Data in the working set will be in the active filesystem
  • That means that snapshot info is not viable for caching, where one of the main benefits of FlexCache is that it allows just the data needed by clients using the cache to be propagated from the origin
