Interactions Between ZFS Compression, Deduplication, and Encryption Properties

Review the following considerations when using the ZFS compression, deduplication, and encryption properties:

  • When a file is written, the data is compressed, encrypted, and the checksum is verified. Then, the data is deduplicated, if possible.

  • When a file is read, the checksum is verified and the data is decrypted. Then, the data is decompressed, if required.

  • If the dedup property is enabled on an encrypted file system that is also cloned and the zfs key –Kor zfs clone –K commands have not been used on the clones, data from all the clones will be deduplicated, if possible.
