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 -K or zfs clone -K commands have not been used on the clones, data from all the clones will be deduplicated, if possible.
