    physical size – the size taken by the files on disk after compression or deduplication

  • Once the managed capacity limits have been reached, no further data protection relationships can be created. However, all existing volumes will continue to be protected with existing schedules.

  • Max Files refers to the sum of the number of files from all volumes in source clusters protected to cloud. In addition to these base files, changed files in each daily incremental Snapshot copy are also stored in the NDAS catalog. It is estimated that the number of files that change every day averages 2% of Max Files. With one year of the daily retention count that NetApp Data Availability Services currently supports, that amounts to a limit of 5M catalog entries and 50M catalog entries for small and medium data capacities, respectively. If the daily change rate is more than 2%, an alert is displayed in the app dashboard to indicate when the catalog entries exceed the 5M or 50M limit.
