Compression

caveat - compression is *not* retroactive, so you should set it on the pool
immediately after creation

::

# See compression settings
zfs get compression
# See compression efficiency
zfs get compressratio
# Set compression (types: lzjb, lz4, gzip-[1-9])
zfs set compression=<type> <pool>

Snapshots

::

# List snapshots
zfs list -t snapshot
# Delete a snapshot
zfs destroy tank/home/thing@tuesday

Rollback


By default, ZFS rollback cannot revert to anything beyond the most recent snapshot. -r lets you go earlier, although this is a destructive operation and deletes the intermediate snapshots

::

zfs rollback tanks/home/dave@tuesday
