The deduplication process on HPE StoreOnce is applied on a per-VTL (Virtual Tape Library), NAS, or Catalyst Store basis. This means that deduplication settings can be configured individually for each store type, allowing for flexible data reduction strategies depending on the specific use case. Deduplication helps to significantly reduce the amount of storage required by eliminating duplicate data, making it a key feature in data protection environments.
