The current ZFS configuration on your server is:pool1 124K 3.

zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname

Creates a snapshot with the given name. All previous modifications by successful system calls to the file system are part of the snapshot

zfs clone [-p] [-o property=value] ... snapshot filesystem|volume

Creates a clone of the given snapshot.

Note:

Because snapshots are fast and low overhead, they can be used extensively without great concern for system performance or disk use .

With ZFS you can not only create snapshot but create a clone of a snapshot.

A clone is a writable volume or file system whose initial contents are the same as the dataset from which it was created. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional disk space. In addition, you can snapshot a clone.

A clone is a writable volume or file system whose initial contents are the same as the original dataset. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional space.

Clones can only be created from a snapshot. When a snapshot is cloned, it creates an implicit dependency between the parent and child.
