This will be a quick overview on how to manage ZFS snapshots and volumes on a FreeBSD system.
A Few Assumptions
Assume that we have a simple volume named storage.
# zfs list NAME USED AVAIL REFER MOUNTPOINT storage 4.81T 2.32T 4.55T /storage
ZFS Snapshot
A ZFS snapshot is a read-only copy of the file system. It will not consume additional space when created. It will however grow in size when data gets modified. Snapshot contents can be accessed through a special .zfs/snapshot directory
