Introduction to OpenZFS

OpenZFS is an open-source storage platform. It includes the functionality of both traditional file systems and volume manager. It has many advanced features including:

  • Protection against data corruption. Integrity checking for both data and metadata.
  • Continuous integrity verification and automatic “self-healing” repair
    • Data redundancy with mirroring, RAID-Z1/2/3 [and DRAID]
  • Support for high storage capacities — up to 256 trillion yobibytes (2^128 bytes)
  • Space-saving with transparent compression using LZ4, GZIP or ZSTD
  • Hardware-accelerated native encryption
  • Efficient storage with snapshots and copy-on-write clones
  • Efficient local or remote replication — send only changed blocks with ZFS send and receive
