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
