The amazing DragonFlyBSD has the fantastic
Hammer2 filesystem:

* Block copy-on-write filesystem
* Instant recovery on mount
* Instant snapshots
* Mounted snapshots are writable
* Automatic snapshotting can be enabled at the system level via periodic scripts
* Default Periodic also does daily bulk pass on the meta-data to free space
* Automatic compression (controllable on directory recursion and per-file basis)
* Automatic de-duplication
* Future master/slave mechanism
* Utilizes a dynamic radix tree
* 64-bit hardlink counter
* 2^63 logical file size limit
* Recursive check codes to detect corruption
* Any number of pseudo-filesystem volumes for each physical hammer2 disk image (also used by snapshots).
