OpenZFS is an advanced copy-on-write file system and volume manager originally developed for Solaris, now maintained by the OpenZFS community. This repository contains the kernel module and userland tools for running OpenZFS on Linux and FreeBSD.

Use cases

set up a ZFS storage pool with snapshots and checksums on Linux
run a file system with data integrity verification and self-healing on FreeBSD
create compressed and encrypted datasets for a NAS
take incremental snapshots and send/replicate datasets between hosts
manage RAID-Z arrays with a combined file system and volume manager
tune ZFS performance for databases or virtualization workloads

When to choose

you need data integrity, checksumming, and self-healing storage on Linux or FreeBSD
you want snapshots, clones, and send/receive for backups or replication
you need flexible pooling (RAID-Z, mirrors) with compression and encryption built in
you run a NAS, home server, or storage appliance and want a proven file system

When to avoid

you only need a simple file system on a single disk without pooling features
you need a file system natively supported out of the box on macOS or Windows
you cannot load kernel modules or build out-of-tree kernel code
your distribution or kernel version is not among the supported releases
