Explanation: BoostFS allows applications without native DD Boost support to leverage DD Boost's deduplication benefits. It provides a seamless data protection layer across various backup applications by streamlining storage and data transfer processes. BoostFS, or Boost File System, is used to enable backup functionality for applications that do not natively support DD Boost. It allows these applications to leverage Data Domain storage efficiency by providing a file system interface. BoostFS essentially provides a method for applications without DD Boost integration to still utilize deduplication and other Data Domain benefits, making it highly effective for environments that want to standardize their storage approach but have a mix of applications with and without DD Boost support.
